Abstract

The invention discloses a spiral wheel-spiral bevel gear retarder, which comprises a motor for supplying power, a flange cover, fasteners and various transmission gears, wherein the flange cover and the fasteners are used for installing and fixing the motor. The flange cover of the motor is fixedly installed on an input surface of a box body via a positioning spigot and the fasteners, an output shaft of the motor is fixedly provided with first level small spiral wheels via bonds and a stop ring, and the first level small spiral wheels are meshed with first level large spiral wheels which are fixedly installed on a shaft table at one end of a cone-shaped gear wheel shaft via bonds and a stop ring. The small cone-shaped gears at both ends of the cone-shaped gear wheel shaft are meshed with the large spiral wheel gears. The large spiral wheel gears are fixedly installed on a three level gear shaft via keys and the three level gear shaft is meshed with the output large spiral wheel which is fixedly installed on the output shaft via keys. The invention has the advantages of strong bearing capacity, large transmission torque, good wear-resisting property and long service life, thereby alleviating the axial load of a bearing and prolonging the service life of the whole machine and greatly reducing the quantity of gear pairs and the production cost.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a helical gear-spiral bevel gear speed reducer, belonging to the field of speed reducers. Background technique [0002] At present, most of the known types of reducers in China are parallel shaft transmission output, such as cycloid reducer, cylindrical gear reducer and so on. With the development of my country's industrial technology, the mechanical structure design tends to be more compact and simple, and the demand for direct-coupled vertical transmission reducers is increasing, gradually replacing the belt drive. At the same time, the transmission torque of the reducer, The requirements for transmission accuracy and reduction ratio are very high, and the requirements for its volume are getting smaller and smaller. Although the known worm gear reducer can realize vertical transmission output and is small in size, the transmission torque is not large enough, the range of its speed ratio is al...
