Abstract
The utility model discloses a combined type hub motor. The combined type hub motor is composed of a rotor, a stator and a motor shaft, wherein a plurality of trapezoid-shaped grooves are uniformly disposed on an outer circle of the rotor; a limiting flange is disposed one side of the trapezoid-shaped grooves; an inner circle of a wheel disc of a hub is provided with trapezoid-shaped tenons which are in cooperation with the trapezoid-shaped grooves; the wheel disc is sleeved on the rotor with one side of the wheel disc pressed against the limiting flange, and the wheel disc is fixed through two fastening screws. The combined type hub motor is convenient to assembly, firm in connection and convenient for maintenance and overhaul, and suitable sizes of the hub can be selected as needed and the hub can be replaced flexibly.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to the wheel hub motor that uses on a kind of electric bicycle.
Background technology
At present, the stator of the permanent magnet DC motor that uses on the electric bicycle is positioned at rotor, and rotor directly is connected with wheel hub.Some design rotor housing and wheel hub design for one, and namely motor can't be pulled down separately from wheel, bring some inconvenience for the maintenance of motor, maintenance, and its hub size can not be adjusted simultaneously.Motor and wheel hub adopt a plurality of bolt in some design, are difficult to guarantee steadiness, and operate comparatively trouble, in case also be inconvenient to behind the bolt corrosion dismantle.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of and the wheel hub combined and instant, connects firm composite type wheel hub motor.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of composite type wheel hub motor, constituted by rotor, stator and motor shaft, and it is characterized in that: be evenly equipped with some dovetail grooves on the rotor cylindrical, dovetail groove one side is provided with spacing flange; Circle is provided with the trapezoidal tenon that cooperates with dovetail groove in the wheel disc of wheel hub, and wheel disc is nested with on rotor, and a side and spacing flange are replaced, and fix by two holding screws.
The utlity model has following beneficial effect: because wheel hub and motor mainly are subjected to radial effect power, can play fixed effect preferably so dovetail groove cooperates with trapezoidal tenon, and both axial forces are less, two holding screws are fixing to get final product so use.It is easy to assembly, is convenient to the maintenance, repair of motor, and wheel hub can be selected suitable dimensions as required, can change flexibly.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of motor after wheel hub is combined.
Among the figure, 1, motor shaft, 2, rotor, 3, dovetail groove, 4, spacing flange, 5, wheel hub, 6, wheel disc, 7, holding screw, 8, trapezoidal tenon.
Embodiment
Shown in accompanying drawing 1,2, a kind of composite type wheel hub motor is made of rotor 2, stator and motor shaft 1, it is characterized in that: be evenly equipped with some dovetail grooves 3 on rotor 2 cylindricals, dovetail groove 3 one sides are provided with spacing flange 4; Circle is provided with the trapezoidal tenon 8 that cooperates with dovetail groove 3 in the wheel disc 6 of wheel hub 5, and wheel disc 6 is nested with on rotor 2, and a side and spacing flange 4 are replaced, and wheel disc 6 is fixing by two holding screws 7 with spacing flange 4.
