Abstract
The invention discloses a starting motor with an anti-skid drive piece, and relates to a starting motor, and solves the problems that a conventional starting motor is low in reliability and is prone to invalidation. The starting motor with the anti-skid drive piece comprises a motor, a spline arranged on the motor shaft, a gear and a drive piece which are both driven to move forwards by the spline, and a rubber plate used for transmitting the torque force of the motor and arranged between the drive piece and the gear. The starting motor with the anti-skid drive piece is characterized in that a through hole is formed on the drive piece, and the through hole penetrates a rubbing surface of the drive piece, which is in contact with rubber plate. After the adoption of the technical scheme in the invention, the starting motor has a simple structure, when grease, rain water, dust and the like enter into the contact surface between the drive piece and the rubber plate, the through hole on the drive piece can scrap the grease, the rain water, the dust and the like, and discharge the grease, the rain water, the dust and the like out of a driving system, and the problem of slipping of the driving system or the toothed ring propping caused by slipping is solved.
Description
Technical field
The present invention relates to a kind of starter motor.
Background technology
In industry, typical starter motor structure is shown in accompanying drawing 1, the course of work is such: motor 1 output is with a gear 4 and driving chip 2 by motor shaft spline 3, when starting, motor 1 provide moment of inertia to gear 4 and driving chip 2, gear 4 and driving chip 2 eject and the engine flywheel engagement by motor shaft spline 3, rely on the rubber disc 6 of adhering on driving chip 2 and gear 4 mutually to push and produce frictional force, motor torsion is passed to engine, thereby start engine.After engine start, motor outage, back into original position to gear 4 and driving chip 2 by spring 5 and engine flywheel to the reaction force of gear 4 and driving chip 2, and motor completes the work of one-period.There is a technological deficiency in this typical structure, owing between driving chip 2 and spline 3, having the high speed relative sliding, in order to reduce frictionalwear each other, need apply oil, when machine operation, spline 3 high speed rotating, easily lubricating oil is thrown between the rubber disc 6 of adhering on driving chip 2 and gear 4, reduce the frictional force between driving chip 2 and rubber disc 6, cause whole drive system to be skidded or apical tooth ring problem (motor gear and engine ring gear can't normally mesh), can't start engine.Also have, most of engine is all at outside work, particularly hay mover and snowblower engine, when mowing or blowing snow, splash a large amount of rainwater, snow-broth, dew and dust etc. enter between driving chip 2 and rubber disc 6, reduce the frictional force between driving chip 2 and rubber disc 6, cause whole drive system to be skidded or apical tooth ring problem, can't start engine.Therefore, the starter motor reliability of this design is low, is easy to lose efficacy.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that the prior art scheme is improved and improved, and the starter motor with anti-skid driving sheet is provided, and to reach, automatically removes greasy dirt, impurity between attached driving chip and rubber disc, avoids the purpose of skidding.For this reason, the present invention takes following technical scheme.
Starter motor with anti-skid driving sheet, comprise motor, be located at the spline on motor shaft, gear and the driving chip that drives and move forward by spline, be located between driving chip and gear for transmitting the rubber disc of motor torsion, it is characterized in that: described driving chip is provided with through hole, and described through hole runs through driving chip and the contacted rubbing surface of rubber disc.The technical program is simple in structure, when grease is arranged, rainwater, when dusts etc. enter into the contact-making surface between driving chip and rubber disc, relative motion and extruding are mutually arranged between driving chip and rubber disc, at this moment the through hole on driving chip is grease, rainwater, dusts etc. are wiped off, from through hole, are discharged to beyond drive system, solve the apical tooth ring problem that drive system is skidded or caused owing to skidding; Through hole runs through driving chip and the contacted rubbing surface of rubber disc, can remove all greasy dirts, the impurity that are positioned on rubbing surface, does not stay dead angle.
As the further of technique scheme improved and supplement, the present invention also comprises following additional technical feature.
Described through hole is circular hole, mounting hole or polygonal hole.
Through hole neighboring on the driving chip rubbing surface is provided with chamfering.Can avoid the rubber disc scratch.
Described driving chip is provided with two spiral-distributed through holes of above equal angles, and through hole is end to end to run through the rubbing surface of driving chip.The end that wherein head end of a through hole to the distance at driving chip center is less than or equal to another through hole to the distance at driving chip center realizes that through hole is end to end, to strike off all greasy dirts, the impurity be positioned on rubbing surface, does not stay dead angle.
Described driving chip is provided with the through hole that three 120 degree equal angles are arranged, three through holes are respectively inner via hole, middle through hole and accessibke porosity, wherein the tail end of inner via hole to the distance at driving chip center is less than the distance of the head end of middle through hole to the driving chip center, the head end of accessibke porosity is less than the distance of the tail end of middle through hole to the driving chip center to the distance at driving chip center, and three through hole spirals arrange to run through the rubbing surface of driving chip.
Described through hole is square opening.
Beneficial effect: the technical program is simple in structure, when grease is arranged, rainwater, when dusts etc. enter into the contact-making surface between driving chip and rubber disc, through hole on driving chip is grease, rainwater, and dusts etc. are wiped off, and be discharged to outside drive system, solve the apical tooth ring problem that drive system is skidded or caused owing to skidding.
