Abstract
The utility model relates to a side-arranged type wire outlet device of electric bicycle motor wheel hubs, which comprises a motor which is installed on the electric bicycle motor wheel hubs, a motor shaft is arranged on a motor end cover through a bearing, a shaft sleeve is arranged on one side of the bearing, an oil seal is arranged between the shaft sleeve and the motor end cover, and a motor wiring harness is traversed from one end of the motor end cover to the other end of the motor end cover. The device is characterized in that a U-shaped groove is made on the external wall of the motor shaft which is positioned in the motor end cover, and the motor wiring harness is traversed through the U-shaped groove on the external wall of the motor shaft. The proposal is characterized in that the motor wiring harness is arranged in the U-shaped groove of the motor shaft external wall, the manufacturing accuracy of the U-shaped groove is easily guaranteed, which enables the thickness of the U-shaped groove to be uniform, thereby the concentrated stress of the motor shaft is prevented, furthermore, the motor wiring harness is arranged in the U-shaped groove, thereby the wiring operation is easy.
Description
Technical field
The utility model relates to the motor of electric bicycle, particularly relates to the side-mounted outgoing line device of electric bicycle hub motor.
Background technology
Electric bicycle hub motor in the market generally adopts at motor shaft intermediate arrangement wire hole, motor harness is passed from the motor shaft wire hole, there is following shortcoming: the one, it is enough big that wire hole should be opened, motor harness could therefrom be passed, and can reduce the intensity of motor shaft after wire hole is held greatly; The 2nd, in the motor shaft course of processing, the axiality of wire hole and motor shaft is difficult to guarantee, causes the motor shaft wall unevenness even easily, concentrates thereby occur stress easily under loading condition, finally may cause shaft break of motor, threaten for bicyclist's personal safety; The 3rd, motor harness is passed from the motor shaft wire hole, damages the crust of motor harness easily, causes extraneous liquid to enter motor internal from breakage, and the lighter reduces motor useful life, and weight person is instantaneous to burn out motor.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of motor shaft intensity to guarantee, can satisfying the instructions for use of electric bicycle; And be easy to guarantee the machining accuracy of motor shaft, guarantee driving safety, the side-mounted outgoing line device of the electric bicycle hub motor that water resistance is good.
The technical scheme of the side-mounted outgoing line device of the utility model electric bicycle hub motor is: comprise the motor that is installed on the wheel hub of electric bicycle, motor shaft is through the Bearing Installation electric motor end cap, one side of bearing is equipped with axle sleeve, between axle sleeve and the electric motor end cap oil sealing is housed, motor harness is from an end of the electric motor end cap other end through electric motor end cap, it is characterized in that: the motor shaft outer wall that is positioned at electric motor end cap is shaped on U type groove, and motor harness is passed in U type groove.
The side-mounted outgoing line device of electric bicycle hub motor of the present utility model, compared with the prior art, from original be the wire hole of motor harness with the motor shaft centre bore, change into motor harness is arranged in the U type groove of motor shaft outer wall, the machining accuracy of U type groove easily guarantees, make U type cell wall thick evenly, thereby avoid motor shaft stress to concentrate; In addition, motor harness is arranged in the U type groove easy operating.
The side-mounted outgoing line device of electric bicycle hub motor of the present utility model has marine glue between the two ends of its U type groove and the motor harness, can play good waterproof effect, and cost is low, and technology is simple, and the related components of motor is not had influence.Its described motor shaft and axle sleeve adopt thread connection, make that connection is firm.Between its described motor shaft and the axle sleeve screw thread glue is arranged, screw thread glue has been arranged, can increase the intensity of connector, improve the sealing property of total, thereby reach waterproof requirement, when motor moves, also can avoid the loosening of parts.Its axle sleeve is an interference fit with cooperating of oil sealing, and this is a kind of waterproof type simple in structure, good stability, and good airproof performance has played the motor internal that enters that stops outside liquid veritably, also can not influence motor properties simultaneously.
Description of drawings
Fig. 1 is the structural representation of the side-mounted outgoing line device of the utility model electric bicycle hub motor.
Embodiment
The utility model discloses the side-mounted outgoing line device of a kind of electric bicycle hub motor, as shown in Figure 1, comprise the motor that is installed on the wheel hub of electric bicycle, bearing 7 and axle sleeve 3 are housed on the motor shaft 2, the bearing 7 outer electric motor end caps 1 that are equipped with, between axle sleeve 7 and the electric motor end cap 1 oil sealing 4 is housed, motor harness 5 is from an end of electric motor end cap 1 other end through electric motor end cap, it is characterized in that: the motor shaft outer wall that is positioned at electric motor end cap 1 is shaped on U type groove 21, motor harness 5 is passed in U type groove 21, compared with the prior art, from original be the wire hole of motor harness with the motor shaft centre bore, change into motor harness 5 be arranged in the U type groove 21 of motor shaft 2 outer walls, the machining accuracy of U type groove easily guarantees, make U type cell wall thick evenly, thereby avoid motor shaft stress to concentrate; In addition, motor harness is arranged in the U type groove easy operating.When reality was made, U type groove was unsuitable excessive, can pass from the space of 3 on motor shaft 2 and axle sleeve swimmingly satisfying motor harness 5, get simultaneously as far as possible little, thereby assurance can not influence the requirement of strength of motor shaft 2 and the water resistance of whole motor.Between the two ends of its U type groove 21 and the motor harness 5 marine glue 6 is arranged, can play good waterproof effect, and cost is low, technology is simple, and the related components of motor is not had influence.Motor harness 5 is coated marine glue 6 after passing and adjust the position from the space between motor shaft 2 and the axle sleeve 3 again at two ends, the viscosity of marine glue should be moderate, and consumption also should be moderate, enters from here to guarantee extraneous liquid that can not.Its described motor shaft 2 adopts thread connection with axle sleeve 3, makes that connection is firm.In actual manufacture process, the pitch of screw thread should be not excessive, because the total of motor is compact, the space is not very plentiful, is not selecting GB pitch for use on shadow motor shaft 2, axle sleeve 3 intensity based as far as possible.Between its described motor shaft 2 and the axle sleeve 3 screw thread glue 8 is arranged, screw thread glue has been arranged, can increase the intensity of connector, improve the sealing property of total, thereby reach waterproof requirement, when motor moves, also can avoid the loosening of parts.Its axle sleeve 3 is an interference fit with cooperating of oil sealing 4, and this is a kind of waterproof type simple in structure, good stability, and good airproof performance has played the motor internal that enters that stops outside liquid veritably, also can not influence motor properties simultaneously.When actual production, axle sleeve 3 should be smooth as much as possible with oil sealing 4 inner lip contact-making surfaces, suggestion surface roughness Ra≤0.6; And add an amount of lubricating grease at axle sleeve 3 and oil sealing 4 inner lip contact-making surfaces, and can not influence the service behaviour of motor like this, can reach good waterproof effect again.
