Abstract

The utility model relates to a parallel-shaft bevel-gear reducer which comprises a box body, wherein the upper end of the box body is provided with an input shaft connected with the output end of a motor. The parallel-shaft bevel-gear reducer is characterized in that the input shaft is coaxially connected with a high-speed gear shaft, and a small high-speed gear which is coaxial with the high-speed gear shaft is in variable transmission connection with a large low-speed gear which is coaxial with the output shaft through an intermediate gear set, so that the output shaft is driven to output rotation. After the adoption of the technical scheme, the parallel-shaft bevel-gear reducer has the advantages of being high in strength, low in noise, modularized, large in transmission torque, and stable in starting.

Description

A kind of parallel axes helical speed reduction gear
Technical field
The utility model belongs to the speed reducer field, is specifically related to a kind of parallel axes helical speed reduction gear.
Background technique
Speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of big torque.For the mechanism of transferring power and motion, the application area of speed reducer is quite extensive at present.Almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the traffic tool, heavy facility for building, the machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch etc.It uses the transmission work from big power, and to little load, accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases the torque function.Therefore be widely used in the conversion equipment of speed and moment of torsion, retarder of a great variety can be divided into gear reducer, worm reducer and plane table thermoconductivity meter according to the transmission type; Can be divided into single-stage and multi-stage speed reducer according to transmission progression difference; Can be divided into cylinder gear speed reducer, cone gear reducer and circular cone-cylinder gear speed reducer according to gear shape; Setting type according to transmission can be divided into expansion, flow deviding type and coaxial-type retarder again, and wherein gear reducer is modal, but the complex structure of gear reducer of the prior art, and strain appears in long-term use the easily, and output torque is little.
