Abstract

The utility model relates to the technical field of the transmission, especially, relate to a novel speed reducer. Including input shaft (1), output shaft (3), driving gear (2), driven gear (4), casing (5), driving gear (2) and driven gear (4) are umbrella tooth, its characterized in that: a plurality of wave teeth (401) are radially arranged on one side of the driven gear (4) provided with the gear teeth. The adoption sets up the ripples tooth at the gear terminal surface and has improved the inside lubricated condition of speed reducer to set up radiating fin externally and reduce the speed reducer temperature, avoid causing the problem of speed reducer lubrication mechanism accelerated ageing because of the high temperature.

Description

Novel speed reducer

Technical Field

The utility model relates to the technical field of the transmission, especially, relate to a novel speed reducer.

Background

The speed reducer has wide application in machinery, the speed reducer can reduce the rotating speed of a prime motor and improve the output torque of the prime motor, and the speed reducer can be divided into a special speed reducer and a general speed reducer according to purposes. Most of the speed reducers for agricultural machines and tools have low output rotating speed, large output torque, complex working environment and high quality requirement on the speed reducers, and the speed reducers are required to have good lubricating and heat radiating capacities in order to prolong the service life of the speed reducers.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the technique that exists is not enough to the aforesaid, provides a novel speed reducer, adopts and set up the ripples tooth at the gear end face and improved the inside lubricated condition of speed reducer to externally set up radiating fin and reduce the speed reducer temperature, avoid causing the problem that speed reducer lubrication mechanism is ageing with higher speed because of the high temperature.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the gear comprises an input shaft, an output shaft, a driving gear, a driven gear and a casing, wherein the driving gear and the driven gear are bevel gears, and a plurality of wave teeth are radially arranged on one side of the driven gear, which is provided with gear teeth.

Further optimize this technical scheme, the ripples tooth is crescent arc.

Further optimize this technical scheme, a side of ripples tooth is provided with and receives the thing groove.

Further optimizing the technical scheme, the length direction of the object accommodating groove is perpendicular to the length direction of the wave teeth.

Further optimize this technical scheme, the outside of casing is provided with radiating fin.

Compared with the prior art, the utility model has the advantages of it is following: 1. the gear oil at the bottom of the speed reducer can be better dispersed to the surface of the driving tooth at the upper part through the arranged wave teeth, so that the driving tooth is lubricated and radiated; 2. the setting is received the thing groove and can be detained the iron fillings in the grease in the slot, avoids foreign matters such as iron fillings to influence the normal meshing of gear.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-3, a novel speed reducer comprises an input shaft 1, an output shaft 3, a driving gear 2, a driven gear 4 and a casing 5 located outside, wherein the driving gear 2 and the driven gear 4 are bevel gears, the driving gear is located at the upper end inside the casing 5, the driving gear 2 and the driven gear 4 are in meshing transmission, a plurality of wave teeth 401 are radially arranged on one side of the driven gear 4, which is provided with gear teeth, the wave teeth 401 are crescent-shaped arcs, an object accommodating groove 402 is arranged on one side of the wave teeth 401, and the length direction of the object accommodating groove 402 is perpendicular to the length direction of the wave teeth 401. The exterior of the housing 5 is provided with heat dissipating fins 501.

During the use, step one, the prime mover passes through input shaft 1 and drives driving gear 2 and rotate, driving gear 2 and the transmission of 4 meshing of driven gear, the inside bottom of 5 inside casings of speed reducer has been filled with gear oil, when driven gear 4 takes place to rotate under the drive of driving gear 2, wave tooth 401 through setting up can be with the gear oil of 5 bottoms of casings spin up, can be with the better surface of attaching to driving gear 2 and driven gear 4 of gear oil, help driving gear 2 and driven gear 4 heat dissipations simultaneously. The heat radiating fins 501 are provided outside the casing 5, and can radiate heat inside the speed reducer to the air better.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
