Model utility content
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of rotor shaft of motor, and it can store a part of lubricant oil, thus extends its life cycle.
The technical solution of the utility model: a kind of rotor shaft of motor, include axis body, axis body is provided with coil winding assembly department, clutch shaft bearing assembly department is also respectively equipped with in the both sides of coil winding assembly department, second axle bearing mount portion, the sidewall of axis body outer end is also provided with helical tooth, second axle bearing mount portion is arranged between helical tooth and coil winding assembly department, axis body outer end is extended with support rim laterally, it is characterized in that: in described axis body, corresponding helical tooth position is provided with shoe cream room, described support rim is provided with oil inlet hole, oil inlet hole and shoe cream room conducting, described axis body is also provided with oil outlet, described oil outlet one end and shoe cream room conducting, the other end extends on the outer wall of the axis body of corresponding helical tooth position, also plug is provided with in described oil inlet hole.
Adopt technique scheme, when adding lubricant oil, open plug, in shoe cream room, lubricant oil is injected by oil inlet hole, lubricant oil is flow on the outer wall of the axis body of corresponding helical tooth position by oil outlet, thus helical tooth and worm gear can be made to lubricate well, the parts of lubricating oil stored in shoe cream room can make its lubrication interval long.
Further setting of the present utility model: described oil outlet is provided with two groups and axis along axis body is symmetrical arranged, often organizes oil outlet and includes three oil outlets axially arranged along axis body.
Adopt above-mentioned further setting, the oil outlet set-up mode of this structure, makes high lubricating effect between helical tooth and worm gear, lubricates more even.
Setting further more of the present utility model: the diameter being positioned at the axis body inside clutch shaft bearing assembly department is less than the diameter of the axis body being positioned at clutch shaft bearing assembly department position, and the axis body diameter be positioned at outside the second axle bearing mount portion is less than the diameter of the axis body being positioned at the second axle bearing mount portion position.
Adopt and above-mentionedly to arrange further again, at installation clutch shaft bearing, the second bearing, can avoid wearing and tearing between clutch shaft bearing and the axis body inside clutch shaft bearing assembly department, wear and tear between the second bearing and the axis body outside the second axle bearing mount portion, thus the working life of motor can be extended.
Of the present utility modelly further to arrange again: the axis body being positioned at coil winding assembly department is axially arranged with anti-slip tank along axis body.
Adopt and above-mentionedly further to arrange again, the anti-slip tank of setting, coil winding can be made firm in location, can not skidding be produced, thus ensure that the service behaviour of motor is more stable.
Further setting more of the present utility model: described plug and described oil inlet hole screw-thread fit.
Adopt and above-mentionedly further to arrange again, this plug and oil inlet hole Placement, conveniently can install, dismantle, structure is simpler.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of rotor shaft of motor, include axis body 1, axis body 1 is provided with coil winding assembly department 2, clutch shaft bearing assembly department 3 is also respectively equipped with in the both sides of coil winding assembly department 2, second axle bearing mount portion 4, the sidewall of axis body 1 outer end is also provided with helical tooth 5, second axle bearing mount portion 4 is arranged between helical tooth 5 and coil winding assembly department 2, axis body 1 outer end is extended with support rim 6 laterally, in described axis body 1, corresponding helical tooth 5 position is provided with shoe cream room 11, described support rim 6 is provided with oil inlet hole 61, oil inlet hole 61 and shoe cream room 11 conducting, described axis body 1 is also provided with oil outlet 12, described oil outlet 12 one end and shoe cream room 11 conducting, the other end extends on the outer wall of the axis body 1 of corresponding helical tooth 5 position, plug 7 is also provided with in described oil inlet hole 61, described plug 7 and described oil inlet hole 61 screw-thread fit, this plug 7 and oil inlet hole 61 Placement, can conveniently install, dismounting, structure is simpler.When adding lubricant oil, open plug 7, in shoe cream room 11, lubricant oil is injected by oil inlet hole 61, lubricant oil is flow on the outer wall of the axis body 1 of corresponding helical tooth 5 position by oil outlet 12, thus helical tooth 5 and worm gear can be made to lubricate well, the parts of lubricating oil stored in shoe cream room 11 can make its lubrication interval long.In the utility model specific embodiment, described oil outlet 12 is provided with two groups and axis along axis body 1 is symmetrical arranged, and often organizes oil outlet 12 and includes three oil outlets 12 axially arranged along axis body 1.Oil outlet 12 set-up mode of this structure, makes high lubricating effect between helical tooth 5 and worm gear, lubricates more even.
