Description
Technical Field
The invention relates to the field of speed reducers, in particular to a speed reducer with a front support.
Background
The speed reducer is widely applied in the mechanical industry, and plays a role in matching rotating speed and transmitting torque between working machines or actuating mechanisms. The bevel gear reducer is one type of bevel gear reducers, is a special reducer for various reaction kettles, adopts a Gleason quasi-hyperbolic tooth type gear, and has the characteristics of large bearing capacity, low noise, long service life, high efficiency, stable operation and the like, and the gear is a hard tooth surface. An input shaft of a bevel gear speed reducer in the prior art is usually a bevel gear shaft, and is generally supported on a shell in a cantilever support mode, so that the support rigidity and strength of the input shaft are insufficient, and the fatigue life of the bevel gear shaft is short.
Disclosure of Invention
In order to overcome the problems of support rigidity and fatigue life of the speed reducer in the prior art and improve output torque, the invention aims to provide the speed reducer with a front support.
The technical scheme adopted by the invention is as follows:
a speed reducer with a front support comprises a shell, an input bevel gear shaft, an intermediate shaft, a large bevel gear, an output gear pair and an output shaft, wherein the large bevel gear is installed on the intermediate shaft, the input bevel gear shaft is meshed with the large bevel gear to drive the intermediate shaft, the intermediate shaft is driven by the output gear pair to drive the output shaft, the middle part and the tail end of the input bevel gear shaft are respectively rotatably supported by a bearing block and a deep groove ball bearing, two tapered roller bearings are installed in the bearing block, and the bearing block is fixedly installed on the shell through screws; an end cover and a mechanical seal are arranged on the outer side of the bearing seat; the deep groove ball bearing is supported on the inner wall in the shell.
Further, the horizontal plane of the axes of the intermediate shaft and the output shaft has a height difference.
Further, the large bevel gear comprises a gear disc and a gear ring, the gear disc is installed on the intermediate shaft through a key, and the gear ring is fixedly installed on the gear disc through a bolt.
Further, the input bevel gear shaft and the large bevel gear have eccentricity in the vertical direction.
After adopting the technical scheme, the invention has the beneficial effects that: the bearing seat provided with two bearings and a deep groove ball bearing are used for supporting the input bevel gear shaft, so that the supporting rigidity and strength of the input bevel gear shaft are ensured, and the fatigue life of the input bevel gear shaft is prolonged; the input bevel gear shaft and the large bevel gear are vertically offset, and meanwhile, the middle shaft and the output shaft are vertically offset, so that the output torque of the speed reducer can be effectively increased.

Detailed Description
The following detailed description of embodiments of the invention is provided in conjunction with the accompanying drawings:
as shown in the figure, the speed reducer with the front support comprises a shell 1, an input bevel gear shaft 2, an intermediate shaft 3, a large bevel gear 4, an output gear pair 5 and an output shaft 6, wherein the large bevel gear 4 comprises a gear disc 41 and a gear ring 42, the gear disc 41 is installed on the intermediate shaft 3 through a key, and the gear ring 42 is fixedly installed on the gear disc 41 through bolts. The large bevel gear 4 is arranged on the intermediate shaft 3, the input bevel gear shaft 2 is meshed with the large bevel gear 4 to drive the intermediate shaft, and the intermediate shaft 3 drives the output shaft through the output gear pair 5.
The middle part and the tail end of the input bevel gear shaft 2 are respectively rotatably supported by a bearing seat 7 and a deep groove ball bearing 8, two tapered roller bearings 9 are arranged in the bearing seat 7 and simultaneously support the middle part of the input bevel gear shaft 2, and the bearing seat 7 is fixedly arranged on the shell 1 by screws; an end cover 10 and a mechanical seal 11 are arranged on the outer side of the bearing seat 7; the deep groove ball bearing 8 is mounted on an inner wall 12 supported in the housing 1 and supports an end portion of the input bevel gear shaft 2. The bevel gear on the input bevel gear shaft 2 is positioned between the bearing seat 7 and the deep groove ball bearing 8, so that the rigidity and the fatigue resistance of the input bevel gear shaft are improved.
The input bevel gear shaft 2 is perpendicular to the intermediate shaft 3 and the output shaft 6, the intermediate shaft 3 is parallel to the output shaft 6, the axis of the input bevel gear shaft 2 and the axis of the output shaft 6 are on the same horizontal plane, the axis of the large bevel gear 4 and the axis of the input bevel gear shaft 2 are provided with a certain eccentric distance in the vertical direction, so that the center distance between the output gear pair 5 is increased, a gear pair with a larger reduction ratio can be arranged, and the output torque is improved.
