Abstract
The utility model relates to a direct current dynamo of a car glass elevator, which comprises a casing, an armature, a carbon brush holder and a speed reducer. The utility model is characterized in that an oil sealing cover which seals and covers the speed reducer in a pressing and casting way is composed of a cover body, an oil sealing rubber pad and a spiral pressure spring which is arranged at the central position of the oil sealing rubber pad. The plastic casing and oil sealing rubber are formed into a whole through hot pressing. The utility model has the advantages of large torque, low noise, good heat dissipation performance, simple processing and long service life.
Description
Technical field
The utility model relates to a kind of direct current machine, exactly is a kind of automotive glass lifter direct current machine.
Background technology
Along with middle people's rapid development of economy, people's living standard improves constantly, the demand of automobile is cumulative year after year thereupon, but production, the manufacture level of China's auto parts and components product also lag behind advanced country at present, the annual a large amount of parts of import that need, automobile door window glass lifter direct current machine is exactly one of them.Though and this class direct current machine better performances of import, complex process and useful life are short.
Summary of the invention
The purpose of this utility model is to provide to people that a kind of torque that replaces imported product is big, noise is low, thermal diffusivity good, and good airproof performance and technology are simple, the automotive glass lifter direct current machine of long service life.
The utility model comprises housing, armature, carbon brush holder and decelerator, it is characterized in that: be made up of lid, oil sealing rubber cushion and elastic pressuring spring through the oil sealing cap that die casting is covered on the decelerator, elastic pressuring spring places between lid and the oil sealing rubber cushion.Elastic pressuring spring shape in the shape of a spiral is placed in the centre of lid and oil sealing rubber cushion.Plastic cover and oil sealing rubber cushion are in aggregates through hot pressing.
Effect of the present utility model:
Oil sealing cap of the present utility model suppresses spring by lid, oil sealing rubber cushion and the helical form of putting its centre and forms, therefore be covered in the oil sealing cap good seal performance but also not easy to wear not only on the spiral shell hub, thereby not only guaranteed motor properties, and the useful life of having improved motor, technology is simple, easy to operate simultaneously.
