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

A kind of Hardened gear face shaft assembled speed reducer
Technical field
The present invention relates to a kind of reductor, specifically a kind of Hardened gear face shaft assembled speed reducer.
Background technology
The reductor of traditional structure adopts upper and lower body structure, supports input, middle, output shaft on lower box successively, Upper and lower body structure is different, and, it is impossible to general, production cost is high for each shaft support bearing difference；In addition, each axle sets gradually, increase The length of reductor, box volume is big, and in case, Dead space is big, increases production cost, and not readily transportable, install.
Content of the invention
For above-mentioned deficiency, the invention provides a kind of structure is simple, case inner structure is compact, each part highly versatile, raw Produce low cost, the Hardened gear face shaft assembled speed reducer be readily transported, installed.
The technical solution used in the present invention is：A kind of Hardened gear face shaft assembled speed reducer, including left and right casing, input gear Axle, intermediate gear shaft and output shaft, its technical characterstic is described input gear axle one end to be worn through double oil seal sealing and connects input transparent cover On, the other end is connected in input boring cover through roller check device；The two ends of output shaft are connected to left and right output through double oil seal sealing Lead to and cover.
Further, described input gear axle, intermediate gear shaft and output shaft arrangement triangular in shape in the axial direction.
Further, the two ends respectively warp of the described two ends of input gear axle, the two ends of intermediate gear shaft and output shaft Identical bearing is supported in left and right box body.
Further, described left and right box body phase is same or symmetrical.
Further, described output shaft is hollow axle.
Using technique scheme, the invention has the beneficial effects as follows：
1st, adopt identical or symmetrical left and right casing, be easy to casing processing and general exchange；Using identical bearings Each axle, is easy to general exchange and stability of strutting system is consistent, is conducive to improving decelerability；
2nd, input gear axle and output shaft are all connected in respective transparent cover by double oil seal, are conducive to improving sealing Energy；The roller check device of the input gear axle other end can effectively prevent reductor from inverting, and improves usage safety performance；
3rd, input gear axle, intermediate gear shaft and output shaft arrangement triangular in shape in the axial direction, each between centers spaces compact, No Dead space in casing, be conducive to reducing box volume, be easy to produce, transport and installing.
Brief description
