Abstract

The utility model discloses a brushless and gearless high-speed motor, comprising a bush 3, a motor core rack 2, bearings 17, 15 and a fixing rack 12 which are arranged on a central shaft 1. A shell 4 and a cycloid shell wheel 8 are connected with each other as one body which is arranged on the central shaft 1 through the bearing 15; a motor rotor 6 is disposed on the bearing 17; an eccentric sleeve 13 is connected with the motor rotor 6 to form one body which is arranged on the central shaft 1 by the bearing 17; a swinging plate 10 is mounted on an eccentric bearing 16 which is arranged on the eccentric sleeve 13; a stationary shaft 11 is disposed on the fixing rack 12; a swing needle combination body 9 is disposed on the cycloid shell wheel 8; a silicon steel sheet 5 is arranged on the motor core rack 2; a magnet 7 is disposed on the motor rotor 6, and the end surface of the bearing 15 is provided with an oil seal 14. The utility model has a compact and reasonable structure, and the motor can realize the high speed in the inner and low speed in the outer. The utility model has the advantages of small size, simple structure, big power and high efficiency, and the integration of the motor and a cycloid speed reducer delivers large variable speed ratio which is suitable for electric bicycles.

Description

The brushless gearless high-speed electric expreess locomotive

Technical field: the utility model relates to high-speed electric expreess locomotive, particularly a kind of brushless gearless high-speed electric expreess locomotive.

Background technology: have or not in the prior art to be brushed with tooth depth speed, the anodontia low speed of brush is arranged, this motor volume is big, and function is little, and gear reduction wants high power to slow down, and noise is big, and energy loss is big.

Summary of the invention: the purpose of this utility model is: a kind of brushless gearless high-speed electric expreess locomotive is provided, and motor and cycloidal reducer are one, can realize high speed in the motor body, external low speed, and it is big to reach power, the purpose that efficient is high.

Formation of the present utility model: by central shaft, motor central frame, casing, silicon steel sheet, rotor, magnet, cycloid shell wheel, the balancing point assembly, balance, fixed axis, fixed mount, eccentric bushing and bearing are formed, mounting bush 3 on central shaft 1, motor central frame 2, bearing 17,15, fixed mount 12, casing 4 and cycloid shell wheel 8 fuse, be installed on the central shaft 1 by bearing 15, rotor 6 is installed on the bearing 17, eccentric bushing 13 and rotor 6 are one, be installed on the central shaft 1 by bearing 17, balance 10 is installed on the capacity eccentric bearing 16, capacity eccentric bearing 16 is installed on the eccentric bushing 13, fixed axis 11 is installed on the fixed mount 12, balancing point assembly 9 is installed on the cycloid shell wheel 8, silicon steel sheet 5 is installed on the motor central frame 2, and magnet 7 is installed on the rotor 6, and oil sealing 14 is arranged on the end face of bearing 15.

Compared with the prior art, the utility model compact conformation is reasonable, and motor can be realized high speed in the body, external low speed, and motor volume is little, and is simple in structure, and power is big, the efficient height, motor and cycloidal reducer are integrated, and gear ratio is big.
