Detailed Description

The invention is further described with reference to the following examples.

Referring to fig. 1, an embodiment of the present invention provides a silent gear reducer, including a gear reducer body and a motor 1 connected to the gear reducer body, where the silent gear reducer further includes an annular sleeve 2, an inner shell 3 and an outer shell 4 made of a sound insulation material, the sleeve 2 is sleeved on a left end of the motor 1, an open end of the outer shell 4 is connected to an outer peripheral side of the sleeve 2 to form a first sealed cavity 5, the inner shell 3 is located in the first sealed cavity 5, an open end of the inner shell 3 is connected to an outer peripheral side of the sleeve 2 to form a second sealed cavity 6, and a right end portion of the motor 1 and the gear reducer body are located in the second sealed cavity 6.

The embodiment of the invention forms a double-layer sound insulation structure for accommodating the gear speed reducer body through the annular sleeve 2, the inner shell 3 made of sound insulation materials and the outer shell 4. Owing to there being the air bed between interior casing 3 and the shell body 4, interior casing 3 plays cushioning effect or additional sound absorption to the noise that the vibration between motor 1 and the planetary gear body rather than being connected caused, makes the sound energy obtain very big decay, later reaches shell body 4 again on the surface, plays cushioning effect or additional sound absorption once more for the effect that gives sound insulation obtains effectual improvement.

In an implementation manner, the open end of the inner housing 3 is provided with a first annular protrusion 7, the outer peripheral side of the sleeve 2 is provided with a first trapezoidal groove 8, the first trapezoidal groove 8 comprises a first portion 11 for supporting the open end of the inner housing 3 and a second portion 12 for matching connection with the first annular protrusion 7, and a sealing member 15 is arranged between the open end of the inner housing 3 and the first portion 11.

In an implementation manner, the open end of the outer shell 4 is provided with a second annular protrusion 9, the outer peripheral side of the sleeve 2 is provided with a second trapezoidal groove 10, the second trapezoidal groove 10 includes a third portion 13 for supporting the open end of the outer shell 4 and a fourth portion 14 for matching and connecting with the second annular protrusion 9, and a sealing member 15 is arranged between the open end of the outer shell 4 and the third portion 13.

By providing the structure of the open end of the inner case 3, the open ends of the inner case 3 and the outer case 4 can be well engaged with the sleeve 2, thereby forming a sealed inner cavity. The structure is simple and easy to implement.

When the motor is installed, the sleeve 2 is firstly sleeved at the left end of the motor 1, the inner shell 3 is further installed, and then the outer shell 4 is installed.

When the inner shell 3 is installed, a sealing member 15 with proper size is placed on the first part 11 of the first trapezoidal groove 8, and then the first annular protrusion 7 on the opening end of the inner shell 3 is inserted into the second part 12 of the first trapezoidal groove 8 until the opening end of the inner shell 3 is abutted with the bottom of the first part 11 of the first trapezoidal groove 8;

when the outer shell 4 is installed, a sealing member 15 with a proper size is placed on the third part 13 of the second trapezoidal groove 10, and the second annular bulge 9 on the open end of the outer shell 4 is inserted into the fourth part 14 of the second trapezoidal groove 10 until the open end of the outer shell 4 abuts against the bottom of the third part 13 of the second trapezoidal groove 10, so that a double-layer sound insulation structure is formed, and the installation is completed.

In one possible embodiment, the gap between the sleeve 2 and the left end of the electric machine 1 is eliminated by pressing the damping element 16.

In a possible way, the lower part of the outer hull 4 is connected to a mounting frame arranged on the ground.

In the embodiment of the invention, the annular sleeve 2, the inner shell 3 made of the sound insulation material and the outer shell 4 form a double-layer sound insulation structure for accommodating the gear speed reducer body, so that the noise caused by the vibration between the motor 1 and the planetary gear body connected with the motor can be effectively reduced, and the sound insulation effect is better.
