Abstract
The invention relates to a starter reduction structure and solves the problem of poor lubrication of the existing automobile-used starter reduction device; the structure comprises an armature shaft, three planet wheels, a gear ring seat, a reduction gear ring, a planet wheel axis and three rollers. The reduction gear ring is fixed on the gear ring seat, the planet wheel axis is arranged in the gear ring seat, the planet wheels are arranged in the planet wheel axis by the rollers, the central axis at the end of the shaft is arranged in the planet wheel axis, and the gear at the end of the shaft is engaged with the planet wheels. The structure is characterized in that the wasted space in the planet wheel axis among the three planet wheels is provided with a stopper; the structure has the advantages that the wasted space among the three planet wheels is provided with the stopper, thus eliminating the wasted space among the three planet wheels and keeping the lubricating oil on the gear all the time, which has the function of full lubrication and increasing the service life of the reduction structure, and at the same time, the usage amount of the lubricating oil can be reduced and fully used, and the noise caused by friction between the gears can be reduced.
Description
Technical field
The invention belongs to a kind of speed reducer, particularly a kind of starter slowing-down structure.
Background technique
Existing vehicle-mounted starting machine speed reducer by armature shaft, three planetary pinions, gear ring base, reduction gear ring, planet wheel shaft, and three rollers constitute.The subject matter that this vehicle-mounted starting machine speed reducer exists is, owing to the wasted space between three planetary pinions is bigger, so, lubricant oil is injected in the slowing-down structure after the slowing-down structure running, lubricant oil will be extruded to three wasted space places between the planetary pinion, and pile up herein, be unfavorable for effective utilization of lubricant oil, also be unfavorable for the lubricated of gear, and shortened the working life of starter motor.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes existing vehicle-mounted starting machine speed reducer lubricant oil and utilizes problem insufficient, the lubrication effect difference, provides that a kind of lubricant oil is fully used, the starter slowing-down structure of high lubricating effect.
The present invention includes armature shaft, three planetary pinions, gear ring base, reduction gear ring, planet wheel shaft, and three rollers, reduction gear ring is fixed on the gear ring base, planet wheel shaft is installed on the gear ring base, planetary pinion is installed on the planet wheel shaft by roller, the central shaft of pivot end is installed on the planet wheel shaft, and the gear of pivot end is meshed with planetary pinion, its special way is, at the wasted space place on the planet wheel shaft, between three planetary pinions block is housed, wasted space between three planetary pinions is filled up, lubricant oil is fully utilized.
The inside edge of described block is the circular arc that concaves, the radius of circular arc is the distance of this circular arc to the armature shaft axle center, the outer ledge of block is cambered outwards circular arc, the radius of circular arc is the distance of this circular arc to the armature shaft axle center, the both sides of the edge of block are the circular arc that concaves, and the radius of circular arc is the distance of this circular arc to the roller axle center.
The invention has the advantages that, wasted space place between three planetary pinions is provided with block, eliminate the wasted space between three planetary pinions, lubricant oil remained on the gear, fully played lubricated effect, improved the working life of slowing-down structure, simultaneously, also reduced the use amount of lubricant oil, lubricant oil is fully utilized, especially in the later stage that product uses, can also reduce fricative noise between gear and the gear.
