Detailed Description

An adaptive connection structure of a pulse code device is characterized in that a pulse code device 10 is connected to an outer end mounting surface of a support 20, an inner end mounting surface of the support 20 is fixedly connected with a motor 1, a transition shaft 30 is coaxially connected to the tail end of a rotor shaft 2 of the motor 1, a shaft sleeve 40 is sleeved on a shaft section 31 of the transition shaft 30, which stretches to a hole cavity of the pulse code device 10, and the shaft sleeve 40 and the stretched shaft section 31 are coaxially arranged and axially form displacement-adjustable locking fit.

In the above scheme, the pulse coder 10 is fixed by the bracket 20, and the bracket 20 is connected with the base or the end cover of the motor 1, so that the position between the pulse coder 10 and the motor 1 is fixed and is in a position matched with the rotor shaft 2 of the motor 1. Support 20 can select the structure of the shape of pi or the cross-section of several characters for use, the inner end of support 20 has the installation face that external turn-ups 21 constitutes to link to each other with the end cover of motor 1, the annular platelike installation face 22 of support 20 outer end is used for connecting fixed pulse coder 10 and the hole portion in annular face middle part supplies transition shaft 30, the installation face that the external turn-ups 21 of the inner end of above-mentioned support 20 constitutes has the connection support connecting plate 23 to link to each other with this assurance pulse coder 10 and motor 1's rotor shaft 2's terminal surface and motor 1's end cover between the border department of the annular platelike installation face 22 of outer end, on heat to avoid motor work adds up originally just transmitting pulse coder 10 in the high temperature environment, reserve accommodation space for transition shaft 30's concrete structure simultaneously.

Referring to the drawings, the inner section 32 of the transition shaft 30 is coaxially inserted into and matched with the axial positioning hole 2a at the tail end of the rotor shaft 2 of the motor 1. The structure is to ensure that the inner section 32 of the transition shaft 30 and the rotor shaft 2 of the motor 1 realize accurate concentric arrangement, because the hole core of the axial positioning hole 2a at the tail end of the rotor shaft 2 of the motor 1 keeps concentric degree or coaxiality with the shaft core, the inner section 32 of the transition shaft 30 is inserted therein, the coaxiality of the transition shaft 30 and the rotor shaft 2 of the motor 1 can be ensured, and generally, the transition shaft 30 and the rotor shaft 2 of the motor 1 are in transition fit.

More preferably, the middle part of the transition shaft 30 is a disk 33, the inner section 32 of the transition shaft is inserted and matched with the axial positioning hole 2a at the tail end of the rotor shaft of the motor 1, the overhanging shaft section 31 of the outer side is provided with an external thread 311, the shaft end is provided with a threaded hole 312 extending towards the side where the disk 33 is located, the internal threaded pipe section of the shaft sleeve 40 is screwed on the external thread 311, the locking screw 50 is matched with the threaded hole 312, and the nail head 51 of the locking screw 50 is locked at the outer end part of the shaft sleeve 40.

In the above scheme, the arrangement of the disc 33 ensures that the transition shaft 30 is inserted into the axial positioning hole 2a at the tail end of the rotor shaft 2 of the motor 1 by the axial depth, i.e. the axial spacing between the transition shaft 30 and the rotor shaft 2 of the motor 1 is ensured.

The nail head 51 of the locking screw 50 is locked at the outside step surface of the necking hole at the outer end of the shaft sleeve 40.
