Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer housing. Background Art

[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear and worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery, especially in automotive power transmission.

[0003] In order to protect the internal components of the reducer from the influence of the external environment, facilitate the effective dissipation of the internal heat of the reducer and maintain the normal operation of its internal working components, the reducer housing is required to protect the internal components of the reducer. The existing reducer housing is usually only provided with mounting holes on one side for fixing. This method will cause the reducer housing to be installed loosely, thereby causing oil leakage. In order to ensure the structural strength of the housing, the existing reducer housing usually adopts the method of increasing the thickness of each part of the housing. However, this structure makes the housing as a whole thick and heavy, and the structural strength at the input shaft and the output shaft is low, which can easily cause damage to the reducer housing. Utility Model Content

[0004] The purpose of the utility model is to provide a reducer housing to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: the reducer housing includes a base and also includes:

[0006] A box cover disposed on the top of the base;

[0007] A first bearing seat is arranged on the inner wall of the box cover, and first bearing covers are arranged on both sides of the first bearing seat. A second bearing seat is arranged on the inner wall of the box cover, and second bearing covers are arranged on both sides of the second bearing seat. A low-speed shaft for reducing the output shaft speed is arranged on one side of the second bearing cover.

[0008] Preferably, a transversely arranged rib is fixed on the outer side of the base, and four anchor bolt holes are opened on the inner wall of the base.

[0009] Preferably, an oil plug for adding oil to the transmission is provided on one side of the base, and an oil dipstick for measuring the amount of transmission oil is provided on one side of the base.

[0010] Preferably, a hook for moving the transmission is fixed to the inner wall of the base, and a limiting hole and a threaded hole are respectively provided on the top of the base.

[0011] Preferably, the top of the box cover is threadedly connected with a lifting bolt for fixing it to the base, and the top of the box cover is threadedly connected with a positioning pin.

[0012] Preferably, a sight hole cover for observing the interior of the transmission is provided on the top of the box cover, and a vent screw plug is provided on the top of the sight hole cover.

[0013] Preferably, a fixing block is fixed to one side of the box cover, and a lifting ring for moving the transmission is fixed to the top of the fixing block.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can fix the gap between the base and the box cover by arranging anchor bolts and lifting bolts, and prevent the reducer housing from being fixed by arranging mounting holes on only one side, resulting in loose installation of the reducer housing and oil leakage. By arranging the first bearing seat, the first bearing cover, the second bearing seat and the second bearing cover, the structural strength of the input shaft and the output shaft can be enhanced, and the low structural strength of the input shaft and the output shaft can be prevented, thereby causing damage to the reducer housing.
