In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide ring gear in a kind of power transmission apparatus of washing machines and ring gear maintainance set assembly, in washer operation process, can reduce noise, improve transmission effect.
To achieve these goals, ring gear in a kind of power transmission apparatus of washing machines designed by the utility model and ring gear maintainance set assembly, comprise ring gear and be positioned at the ring gear maintainance set outside ring gear, gear in described ring gear is angular gear, described ring gear lower end is provided with coaxial bulge loop arranged with it, the lower surface of described bulge loop is evenly distributed with some projections, between described projection, forms draw-in groove; The cover plate that input axle sleeve comprises input axle sleeve body and is fixedly connected with input axle sleeve body, described cover plate is provided with the projection suitable with described draw-in groove, and described cover plate periphery is fixedly connected with the lower end of described ring gear maintainance set.The engagement of angular gear is good, stable drive, noise is little, coordinating again by projection and draw-in groove, make that input axle sleeve and ring gear are stable to be connected, improve the transmission effect between them, and be fixedly connected with cover plate due to ring gear maintainance set, make ring gear maintainance set and ring gear synchronous axial system, reduce noise further.
Preferably, described projection is fan-shaped setting, and coaxially arranges with ring gear.
Preferably, described projection is provided with the material reducing groove with its similar shape, and material reducing groove can reduce the weight of ring gear entirety, thus reduces costs, and can reduce the overall damage under effect of inertia of ring gear simultaneously.
Further, the external diameter three of the external diameter of described bulge loop, the external diameter of ring gear and projection is equal, and the internal diameter of described bulge loop is less than the internal diameter of ring gear, and the internal diameter of described projection is greater than the internal diameter of bulge loop.
A kind of fixed form between input axle sleeve body and cover plate, is provided with a through hole in the middle of described cover plate, described through hole extends to form an extending seat downwards, and described input axle sleeve body upper end to embed in described extending seat and is fixedly connected with it.
Further, described extending seat and described cover plate arc-shaped transition.
A kind of fixed form between ring gear maintainance set and cover plate, described ring gear maintainance set lower end is provided with flange, and described flange is riveted mutually with described cover plate.
Ring gear in a kind of power transmission apparatus of washing machines that the utility model obtains and ring gear maintainance set assembly, its technique effect is: by the improvement of said structure, make ring gear and ring gear maintainance set synchronous axial system, improve ring gear in use transmission stability, noise is little, service life is of a specified duration, and is connected with input axle sleeve is stable, improves transmission effect.
