Abstract
A starting motor with an anti-skid driving sheet relates to starting motors. An existing starting motor is low in reliability and easy to fail. The starting motor with the anti-skid driving sheet comprises a motor, a spline arranged on a motor shaft, a gear driven by the spline to move forward and the driving sheet. A rubber disk is arranged between the driving sheet and the gear and used for transmitting motor torque. The starting motor with the anti-skid driving sheet is characterized in that the driving plate is provided with a through hole, and the through hole penetrates through the friction surface where the driving sheet is contacted with the rubber disk. The starting motor with the anti-skid driving sheet is simple in structure. When oil, rain and dust and the like enter the friction surface between the driving sheet and the rubber disk, the through hole on the driving sheet scrapes the oil, the rain, the dust and the like and discharges the oil, the rain, the dust and the like out of a driving system, and the problems of skidding of the driving system and ring gear butting caused by the skidding are solved.
Description
Technical field

Background technology
Typical starter motor structure is seen accompanying drawing 1 in the industry; The course of work is such: motor 1 output is with a gear 4 and driving chip 2 through motor shaft spline 3; When motor 1 starts, provide moment of inertia to gear 4 and driving chip 2, gear 4 and driving chip 2 eject and the engine flywheel engagement through motor shaft spline 3, rely on rubber disc 6 mutual extrusion of adhering on driving chip 2 and the gear 4 to produce frictional force; Pass to engine to motor torsion, thereby start engine.After the engine start, the motor outage back into original position to gear 4 and driving chip 2 for the reaction force of gear 4 and driving chip 2 by spring 5 and engine flywheel, and motor is accomplished the work of one-period.There is a technological deficiency in this typical structure, owing to have the high speed slide relative between driving chip 2 and the spline 3, and in order to reduce friction and wearing and tearing each other; Need apply oil, when machine operation, spline 3 high speed rotating; Be prone to be thrown to lubricating oil between the rubber disc 6 of adhering on driving chip 2 and the gear 4; Reduce the frictional force between driving chip 2 and the rubber disc 6, cause whole drive system to be skidded or apical tooth ring problem (motor gear and engine ring gear can't normal engaged), 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 the rubber disc 6; Reduce the frictional force between driving chip 2 and the 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.
The utility model content
The technical problem that the utility model will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and the starter motor of the anti-gliding style driving chip of band is provided, and remove to attach greasy dirt, impurity between driving chip and the rubber disc automatically to reach, and avoid the purpose of skidding.For this reason, the utility model is taked following technical scheme.
The starter motor of the anti-gliding style driving chip of band; Comprise motor, be located at the spline on the motor shaft, gear and the driving chip that passes through the spline drive and move forward; Be located at the rubber disc that is used to transmit motor torsion between driving chip and the gear; 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 present technique scenario-frame is simple, as grease, and rainwater; When dusts etc. enter into the contact-making surface between driving chip and the rubber disc, relative motion and mutual extrusion are arranged between driving chip and the rubber disc, at this moment the through hole on the driving chip is grease; Rainwater; Dusts etc. are wiped off, from through hole, are discharged to beyond the drive system, solve that drive system is skidded or because the apical tooth ring problem of skidding and causing; 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 the rubbing surface, does not stay the dead angle.
As the further of technique scheme improved and replenish, the utility model 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.
Said 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.Wherein the distance at the head end of a through hole to the driving chip center distance that is less than or equal to end to the driving chip center of another through hole realizes that through hole is end to end, to strike off all greasy dirts, the impurity that is positioned on the rubbing surface, does not stay the 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 distance at the tail end of inner via hole to driving chip center is less than the distance at head end to the driving chip center of middle through hole; The distance at the head end of accessibke porosity to driving chip center is less than the distance at tail end to the driving chip center of middle through hole, and three through hole spirals are arranged to run through the rubbing surface of driving chip.
Described through hole is a square opening.
Beneficial effect: the present technique scenario-frame is simple, as grease, and rainwater; When dusts etc. enter into the contact-making surface between driving chip and the rubber disc; Through hole on the driving chip is grease, rainwater, and dusts etc. are wiped off; And be discharged to outside the drive system, the solution drive system is skidded or because the apical tooth ring problem of skidding and causing.
