Hard-tooth-surface shaft-mounted speed reducer

Abstract

The invention relates to a hard-tooth-surface shaft-mounted speed reducer. The hard-tooth-surface shaft-mounted speed reducer comprises a left box, a right box, an input gear shaft, an intermediate gear shaft and an output shaft. One end of the input gear shaft is connected to an input piercing cover in a penetrating and sealing mode through double oil seals, and the other end of the input gear shaft is connected to the interior of an input gland through a roller brake. The two ends of the output shaft are connected to a left output through cover and a right output through cover in a penetrating and sealing mode through double oil seals. By the adoption of the left box and the right box which are the same or are symmetrical, machining and general interchange of the boxes are facilitated. The shafts are supported by bearings which are the same, so that general interchange and consistency of supporting stability are facilitated, and improvement on decelerability is facilitated.

Description

technical field [0001] The invention relates to a reducer, in particular to a hardened shaft-mounted reducer. Background technique [0002] The traditional structure of the reducer adopts the upper and lower box structures, and the lower box supports the input, intermediate, and output shafts in sequence. The upper and lower box structures are different, and the supporting bearings of each shaft are different, which cannot be used universally, and the production cost is high; In addition, each The shafts are arranged in sequence, which increases the length of the reducer, the box body is bulky, and the invalid space in the box is large, which increases the production cost and is not convenient for transportation and installation. Contents of the invention [0003] In view of the above disadvantages, the present invention provides a shaft-mounted gear reducer with hard tooth surfaces, which is simple in structure, compact in the box, highly versatile in components, low in p...
