Abstract
The utility model discloses a worm-gear case which comprises a worm-gear case body. A fluid pipeline is arranged on one side of the worm-gear case body. A hollow cavity is arranged on the middle portion of the worm-gear case body. Protruding blocks which are used for clamping a worm-gear shaft are arranged inside the hollow cavity. According to the worm-gear case, the hollow cavity is arranged on the middle portion of the worm-gear case body, raw materials are saved, production cost is reduced, the weight of the worm-gear case is lightened, the worm-gear case is convenient to transport, the hollow cavity is communicated with the fluid pipeline, the temperature of fluid is reduced, the service life of the worm-gear case is prolonged, the protruding blocks are designed to be in special shapes and are enabled to clamp the worm-gear case installed inside the worm-gear case, and therefore connecting fastness of the worm-gear case and the worm-gear shaft is guaranteed. The worm-gear case is simple in design and convenient to achieve, and has good application prospect.
Description
