Abstract
The utility model discloses a worm wheel-type gear box. The worm wheel-type gear box is composed of a motor, a cabinet, a worm gear, a change gear pair, a spline shaft, a shaft, selector blocks and shifting slide blocks. The motor is connected with the worm and meshed with the worm wheel; the worm wheel and the change gear are arranged on the same shaft which is fixed inside the cabinet through a bearing; the spline shaft is connected with the other change gear and the other selector block and is fixed inside the cabinet through a bearing; two shifting slide blocks are arranged on the same shifting shaft and are separately connected with respective selector fork which touches the selector block respectively; the shifting shaft is fixed inside the cabinet. The utility model has the advantages of simple structure, good deceleration and ability and changeable speed.
Description
Technical field
The utility model relates to a kind of worm-gear type gearbox.
Background technique
Use the gearbox that many forms are arranged in the machinery industry, speed reducer is made up of the axle of gear pair, connection gear pair and the bearing and the casing of back shaft mostly, and rotating speed of motor is reduced to low speed, need to slow down through multi-stage gear is secondary, the structure more complicated, output speed is fixed, and can not be fit to different loads.
Summary of the invention
The purpose of this utility model provides a kind of worm-gear type gearbox.For achieving the above object, the utility model is taked following design proposal:
Described worm-gear type gearbox is by motor, cabinet, worm and gear, the speed change gear pair, splined shaft, axle, shifting block, the variable block slide block is formed, described motor connects described worm screw and meshes with described worm gear, described worm gear and described speed change gear are installed on the same axle, described axle by bearing fixing in described cabinet, another speed change gear and the described shifting block that connect described speed change gear pair on the described splined shaft, described splined shaft by bearing fixing in described cabinet, described variable block slide block is two, with being installed on the variable block axle, and be connected with separately shift fork, described shift fork contacts with described shifting block separately, and described variable block axle is fixed in the described cabinet.
The utility model has the advantages that: simple in structure, decelerability well and changeable speed.
Description of drawings:
