Technical Field

The invention relates to a transmission part in a machine, in particular to a device for driving a driven shaft to rotate after a driving shaft of a power machine rotates to a high speed at the initial starting.

Background

Because the power required by the machine in normal operation is far lower than that of the machine in initial starting, the traditional method is to use a larger power or a matched clutch to idle at first, namely, no load is carried out, and when the high speed is reached, the clutch is closed to drive a working part to operate so as to do work. The former is a waste caused by pulling a trolley by a big horse, and the latter is necessary to increase the investment cost of an accessory clutch and increase the labor capacity of staff.

Disclosure of Invention

The invention aims to overcome the defects and provide an energy-saving starter which has simple structure, is durable, does not need the operation of staff and automatically drives a working part to rotate when the high speed is reached after the initial starting, and is realized by adopting the following technical scheme.

The centrifugal force acts to throw stuck or entangled objects around the centre of rotation and free them, according to the principle that the machine develops centrifugal force during rapid operation. A driving disk is installed on the top head in front of a flat driving shaft driven by power, at least two strip-shaped sliding blocks (called sliding blocks for short) are arranged on the inner edge of the disk at equal intervals on the circumference, magnets which attract each other are arranged between the top head at the inner end of each sliding block and the outer edge of a central shaft, each sliding block is respectively positioned in a slide way, the top head at the outer end of each sliding block is opposite to the space in the driven disk, a plurality of idler wheels which are annularly arranged are arranged on the periphery of two sides of the space, the original reason of the magnet is different from that of a tension spring, the tension spring is lengthened and then becomes larger so that the sliding block is difficult to enter the space, if the tension force is too small, the sliding block is stretched into the space of the driven disk, the space is too early to play a role in energy saving, the magnets are just opposite, the magnets cannot move when the centrifugal force is insufficient, the sliding block is separated from a, the suction force can be controlled at will, and the long-strip-shaped sliding block can automatically return when the operation is stopped.

When the rotating shaft is vertically placed, the driving shaft is positioned at the lower part and the driven shaft is positioned at the upper part, and only the slide ways are required to be installed to be low inside and high outside, so that the magnet is saved.

The working principle is as follows: the power, namely the motor or the internal combustion engine, is only the driving shaft running for idle running without load when starting, so that the needed power is smaller, after starting, the driving shaft is rotated from low speed to high speed to form a certain centrifugal force to separate the inner end top head of the sliding block from the fixed magnet, after separation, the front end of the sliding block is inserted into the space of the driven disk in quick sliding, so as to drive the driven disk to be connected with the driven shaft and the working part to run to do work, before insertion, the outer end top head of each sliding block is attached to the inner edge of the annularly arranged idler wheel, and in the rotating process, each idler wheel is pushed to rotate in situ, so that the. Or the sliding block slides outwards and upwards along the slide way with low inside and high outside under the action of centrifugal force, the sliding block slides downwards and inwards to return under the action of self gravity after the operation is stopped, and the castors can be arranged at the front lower edge and the rear lower edge of the sliding block to reduce the friction resistance in the sliding process if necessary.

In summary, the key points of the technical scheme of the invention are as follows: a driving disc is installed at the front end of a flat driving shaft driven by power, at least two sliding blocks are arranged on the inner edge of the disc at equal intervals on the circumference, magnets which attract each other are arranged between the inner end ejecting heads of the sliding blocks and the outer edge of a central shaft, the sliding blocks are respectively positioned in a slide way, the outer end ejecting heads of the sliding blocks are opposite to the inner edge space of a driven disc, a plurality of idler wheels which are annularly arranged are arranged on the two sides of the space, when the rotating shaft is vertically arranged, the driving shaft of the rotating shaft is arranged below, the driven shaft of the rotating shaft is arranged above, and the slide ways on the periphery are low in inside.

Casters are arranged at the front lower edge and the rear lower edge of the sliding block.

The invention has the beneficial effects that: firstly, the power matching can be reduced to achieve the purposes of saving energy and reducing cost; and after the starting, the slide block drives the driven disk and the driven shaft to operate in automatic sliding, so that the power and the labor are saved.

Detailed Description

The following is further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, a driving disc 2 is installed at the front top of a flat driving shaft 11 driven by power, a driven disc 1 is installed at the rear end of a driven shaft, the top of the front end of the driving shaft 11 extends into a central inner ring 5 of the driven disc 1 to prevent deviation, four strip-shaped sliders 4 are arranged at the inner edge of the driving disc 2 and are arranged at equal intervals on the circumference, a fixed magnet 6 and a magnet 7 moving along with the sliders are arranged between the top of the inner end of each slider 4 and the outer edge of the central driving shaft 11 and are mutually attracted, the sliders are respectively positioned in a slideway 9, the top of the outer end of each slider is opposite to the inner edge space of the driven disc 1, a plurality of idler wheels 3 are annularly arranged around the two sides of the space, the magnets are selected instead of tension springs, the tension springs are different from the magnets, the tension springs are lengthened, the tension of the tension springs is increased to make the sliders difficult to enter the space, if the tension is too small, the tension, the magnets are opposite to each other, and cannot move when the centrifugal force is insufficient, the magnets are separated from the fixed magnets when rotating at a high speed, the attraction force between the magnets is correspondingly smaller when the magnets are farther away, the magnets are easy to insert into a space, the magnitude of the attraction force can be controlled at will, and particularly the elongated sliding blocks 4 can automatically return when the operation is stopped.

The working principle is as follows: the power, namely an electric motor or an internal combustion engine (not shown in the figure), only a driving shaft 11 runs into idle state without load when the engine is started initially, so that the needed power is smaller, centrifugal force of a certain degree is formed from low speed to high speed after the engine is started to promote the top heads at the inner ends of sliders 4 to be separated from fixed magnets 6, the front ends of the separated sliders are inserted into the space of a driven disc 1, namely between two side idler wheels 3 during fast sliding, so that the driven disc 1 and a driven shaft 12 and a working component (not shown) connected with the driven shaft are driven to run to do work, the top heads at the outer ends of the sliders 4 are attached to the inner sides of the idler wheels arranged in a ring shape before the insertion, and the idler wheels are pushed to rotate in situ during rotation.

Referring to fig. 3, when the shaft is vertically disposed with the driving shaft 11 on the lower side and the driven shaft 12 on the upper side, the proximal ends of the driving and driven shafts (not shown) are located in the inner race 5, and it is only necessary to install the respective slide ways 13 at the inner lower and outer higher, thereby omitting the magnets. The slide block 10 slides outwards and upwards along the slide way 13 with low inside and high outside under the action of centrifugal force, and slides downwards and inwards to return under the action of self gravity after the operation is stopped.
