A central shaft (1) is equipped with a motor core frame (7), bearings (11) and (22) and a fixing frame (12). A machine shell (3) and a cycloid shell (10) are linked as a whole and are installed at the central shaft (1) by the bearing (22). A motor rotor core (13) is installed at the bearing (11). An eccentric cover (20) is installed at the motor rotor core (13). A rolling needle (21) and a wobble plate (15) are installed at a rolling needle frame (14) which is installed at the eccentric cover (20). A fixing shaft (9) is installed at the fixing frame (12). A swing needle (8) is installed at a cycloid shell (10). A silicon steel plate (6) is installed at the motor core frame (7). A motor rotor (5) is installed at a motor rotor core (13). A magnet (4) is installed at the motor rotor (5). The utility model has compact and reasonable structure; the motor can realize the high speed inside body and low speed outside body; the motor size is small; the power is large, and the efficiency is high; the motor and the cycloid speed reducer are integrated; the variable ratio is large; the utility model is applicable to an electric bicycle.
Description
The utility model relates to high-speed electric expreess locomotive, particularly a kind of brushless gearless high-speed electric expreess locomotive.
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.
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, casing, magnet, rotor, silicon steel sheet, motor central frame, balancing point, fixed axis, the cycloid shell, bearing, fixed mount, the rotor heart, balance, eccentric bushing and needle roller are formed, go up installation motor central frame (7) at central shaft (1), bearing (11) (22), fixed mount (12), casing (3) and cycloid shell (10) fuse, be contained on the central shaft (1) by bearing (22), the rotor heart (13) is contained on the bearing (11), eccentric bushing (20) is contained on the rotor heart (13), needle roller (21) and balance (15) are contained on the needle roller frame (14), needle roller frame (14) is contained on the eccentric bushing (20), fixed axis (9) is contained on the fixed mount (12), balancing point (8) is contained on the cycloid shell (10), silicon steel sheet (6) is contained on the motor central frame (7), rotor (5) is contained on the rotor heart (13), and magnet (4) is contained on the rotor (5).
Packing ring (2), motor central frame (7), bearing (11) (22), fixed mount (12), neck bush (16), oil sealing (17), external bushing (18) is stationary fit with central shaft (1), the rotor heart (13) and bearing (11) are for movingly, eccentric bushing (20) is stationary fit with the rotor heart, needle roller (21) and needle roller frame (14) are for movingly, balance (15) and needle roller frame (14) are for movingly, fixed axis (9) is an interference fit with fixed mount (12), balancing point (8) is an interference fit with cycloid shell (10), silicon steel sheet (6) is stationary fit with motor central frame (7), rotor (5) is an interference fit with the rotor heart (13), magnet (4) is stationary fit with rotor (5), and needle roller frame (14) and eccentric bushing (20) are for movingly.
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 power is big, the efficient height, motor and cycloidal reducer are integrated, and gear ratio is big.
