Embodiment

[0019] Embodiment: A motor reduction gear box, which includes a motor 13 , a gear box body 1 , an end cover 9 and a gear reduction mechanism 3 . The gear reduction mechanism 3 is a four-stage gear reduction mechanism, which is arranged in the sealed cavity between the reduction box body 1 and the end cover 9. A groove 37 is arranged on the inner side of the end cover, and Four accommodating holes 38 are provided on the bottom surface, and corresponding accommodating holes 31 are provided on the box body 1 . The four-stage gear reduction mechanism 3 is a standard structure, and each stage of transmission components is composed of a transmission shaft, an input gear and an output gear. The input gear of the second stage is meshed, and the upper and lower ends of the transmission shaft are fixed in the housing holes 31 and 38 on the box body 1 and the end cover 9 through bearings. The input gear 6 of its first transmission part meshes with the motor drive shaft 12 .

Abstract

The invention relates to a motor gear reduction box which comprises: a gearbox, a covering that match with the box and a gear reduction mechanism is arranged in the gearbox. The gear reduction mechanism is arranged in the reduction box, the two ends of each gear shafting are fixed in the holes on the box and covering. Outside of the covering equipped a ring boss; the motor directly connects with the gearbox via the covering; the input axle of the motor is geared with the gear reduction mechanism via the inside connection hole; on the bottom of the box provided the output axle connection hole.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a motor reduction gearbox. Background technique [0002] At present, the use of gearboxes is becoming more and more extensive, and various gearboxes have appeared one after another. For example, the 70JB motor reduction gearbox produced by our company includes a motor, a reduction box and a gear reduction mechanism. The gear reduction mechanism adopts four-stage reduction and is installed in the reduction box. On the drive shaft of the motor, the output shaft is pivotally connected to the box body through a bearing. One end of the motor is provided with an end cover, which is positioned by a pressing plate and then connected to the end cover of the reduction box body. The motor gearbox with this structure has many parts and a relatively complicated structure, which not only has high manufacturing cost, complicated manufacturing process and high manufacturing difficulty, but also is not co...
