Abstract
The utility model relates to a steel ball axial positioning starter, which comprises a casing. The casing is internally equipped with a DC motor, an electromagnetic switch, a shift fork and a unidirectional clutch, wherein, one end of the shift fork is connected with the electromagnetic switch and the other end is arranged inside a groove of the unidirectional clutch. The front part of the unidirectional clutch is provided with a gear which is meshed with an internal-combustion engine flywheel; a driving shaft perforated into the interior of the unidirectional is connected with a rotor shaft of the DC motor through a planet gear. The front end face of the rotor shaft and an action end of the driving shaft form a location fit through the clearance among steel balls. The utility model provides a steel ball axial positioning starter with simple structure, convenient assembly, shortened starter axial length and lower operational friction resistance.
Description
(1) technical field
The utility model relates to automobile starter, particularly a kind of starter motor that adopts the steel ball axially locating.
(2) background technique
Starter motor is as the starting equipment of motor car engine, comprise casing, direct current motor is housed in the casing, magnetic switch, shift fork, parts such as overrunning clutch, one end of shift fork connects magnetic switch, the other end is contained in the groove of overrunning clutch, after the magnetic switch adhesive, it is that rotate at the center with the locating stud that moving iron core drives shift fork, the lower end of shift fork promotes the overrunning clutch reach, gear and the engagement of the gear ring on the internal combustion engine flywheel until the overrunning clutch front portion, simultaneously, the roller wedging live axle in the overrunning clutch, the transmission of torque of rotor shaft makes internal-combustion engine rotation starting to the internal combustion engine flywheel gear ring.
Rotor shaft must have certain axial clearance with live axle when high speed rotating, and the control in this gap, traditional mode has the collar formula, but collar formula structure must be offered the groove that collar is installed on rotor shaft, and the parts peculiar of control card delineation position, the structure more complicated, and also difficulty is installed, and also whole starter motor axial length can extend.
(3) summary of the invention
For the rotor shaft that solves existing starter motor and the above-mentioned deficiency of the Placement between the live axle, the utility model proposes the steel ball axially locating starter motor of a kind of simple in structure, easy to assembly, starter shaft to shorten length.
Steel ball axially locating starter motor, comprise casing, direct current motor, magnetic switch, shift fork, overrunning clutch are housed in the casing, one end of shift fork connects magnetic switch, the other end is contained in the groove of overrunning clutch, the front portion of described overrunning clutch has and the internal combustion engine flywheel meshed gears, live axle is arranged in the inside of described overrunning clutch, described live axle is connected with the rotor shaft of described direct current motor by planetary pinion, cooperates by location, steel ball gap between the effect end of the front-end face of described rotor shaft and described live axle.
Technical conceive of the present utility model is: adopt steel ball axial clearance location to cooperate between described rotor shaft and the described live axle, linkage structure is fairly simple, effectively controlled the axial clearance between rotor shaft and the live axle, assemble more convenient, part number also suitably reduces, and the operation friction resistance is lower.
The beneficial effects of the utility model are: simple in structure, easy to assembly, starter shaft is lower to shorten length, operation friction resistance.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to accompanying drawing: steel ball axially locating starter motor, comprise casing, direct current motor 10 is housed in the casing, magnetic switch 11, shift fork 12, overrunning clutch 13, one end of shift fork 12 connects magnetic switch 11, the other end is contained in the groove of overrunning clutch 13, the front portion of described overrunning clutch 13 has and internal combustion engine flywheel meshed gears 15, live axle 2 is arranged in the inside of described overrunning clutch 13, described live axle 2 is connected with the rotor shaft 8 of described direct current motor by planetary pinion 14, fix by bearing pin between described live axle 2 and the planetary pinion 14, be connected by ring gear between described planetary pinion 14 and the rotor shaft 8, cooperate by location, steel ball 4 gaps between the effect end of the front-end face of described rotor shaft 8 and described live axle 2.
Working principle is: after magnetic switch 11 adhesives, it is that rotate at the center with locating stud 17 that moving iron core drives shift fork 12, the lower end of shift fork promotes overrunning clutch 13 reaches, until the gear 15 of overrunning clutch 13 front portions and the gear ring engagement on the internal combustion engine flywheel, simultaneously, roller 18 wedging live axles 2 in the overrunning clutch 13, the moment of rotor shaft 8 is delivered on the live axle 2 by planetary pinion 14, further be delivered to again on the gear 15 of overrunning clutch 13 front portions, gear 15 passes to the internal combustion engine flywheel gear ring, internal-combustion engine rotation starting.
Adopt steel ball axial clearance location to cooperate between described rotor shaft and the described live axle, linkage structure is fairly simple, has effectively controlled the axial clearance between rotor shaft and the live axle, assembles more conveniently, and part number is suitably minimizing also, and the operation friction resistance is lower.
Among the figure, the radial location of rotor shaft 8 is by rotor shaft lining 7 and rolling bearing 9 supportings, and axially locating is by rolling bearing 9 and steel ball 4 restrictions; The radial location of live axle 2 is by live axle lining 1 and 5 supportings of middle cover lining, and axially locating is by pad 6 restrictions at middle cover 3 two ends, and steel ball 4 also plays a part live axle 2 auxiliary axially locating.
Claims (1)
1. steel ball axially locating starter motor, comprise casing, direct current motor, magnetic switch, shift fork, overrunning clutch are housed in the casing, one end of shift fork connects magnetic switch, the other end is contained in the groove of overrunning clutch, the front portion of described overrunning clutch has and the internal combustion engine flywheel meshed gears, live axle is arranged in the inside of described overrunning clutch, described live axle is connected with the rotor shaft of described direct current motor by planetary pinion, it is characterized in that: cooperate by location, steel ball gap between the effect end of the front-end face of described rotor shaft and described live axle.
