Abstract
The utility model discloses an isolator used in an automotive starter, which comprises a first gear (7), a second gear (2), a driving shaft (1), a star gear (5) and a sleeve (3) sheathed on the driving shaft (1) in a sliding manner, wherein an oil seal component (8) is installed between the sleeve (3) and the driving shaft (1), the oil seal component (8) is arranged on the front end surface of the sleeve (3), and the front end surface of the oil seal component (8) props against the rear end surface of the second gear (2). The isolator used in the automotive starter can effectively avoid the wear of the sleeve and the driving shaft caused by impurities and dust attached on the driving shaft, thereby avoiding potential safety hazards, and prolonging service life.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of one-way element that is used for automobile starter.
Background technique
Thereby being the electric energy with storage battery, automobile starter is converted into mechanical energy to drive the machine that the engine flywheel rotation realizes engine start.And one-way element is the transmission device that on the starter motor moment of torsion of motor production is passed to flywheel.Existing one-way element comprises that mainly first gear, second gear, live axle, star wheel and flip sleeve are combined in the sleeve on the live axle, described first gear is fixed on an end (first gear and star wheel are generally made an integral body) of sleeve, the other end of described sleeve is installed in the center hole of star wheel one end through a plurality of rollers and flat spring, described second gear is fixed on an end of described live axle, and the front-end face of the ear end face of described second gear and described sleeve offsets.During work, rotate by motor, drive the gear rotation on the motor output shaft, thereby drive first gear rotation of the one-way element that is meshed with gear on the motor output shaft, second gear on the one-way element is rotated simultaneously, through the engagement of second gear and motor car engine flywheel, thus ato unit.But existing one-way element is in automobile starter condition very bad working environment, when second gear and engine flywheel engagement driving, second gear of high speed rotating and flywheel mutual friction meeting mutually produce impurity and dust, and impurity and dust are diffused into an end of one-way element sleeve easily, and then attached on the live axle, these impurity and dust can cause wearing and tearing to sleeve and live axle, even live axle is stuck, caused potential safety hazard like this, and influenced one-way element even working life motor.
Summary of the invention
Technical problem to be solved in the utility model is: thus provide a kind of impurity and dust can effectively avoided attached to the one-way element that is used for automobile starter that causes the wearing and tearing of sleeve and live axle to avoid potential safety hazard, increase the service life on the live axle.
The technical scheme in the invention for solving the above technical problem is: a kind of one-way element that is used for automobile starter, comprise that first gear, second gear, live axle, star wheel and flip sleeve are combined in the sleeve on the live axle, be provided with the oil sealing parts between described sleeve and the live axle, described oil sealing parts are arranged on the front-end face of described sleeve, and the front-end face of described oil sealing parts is butted on the ear end face of second gear.
Compared with prior art, advantage of the present utility model is: this is used for being provided with the oil sealing parts between the sleeve of one-way element of automobile starter and the live axle, described oil sealing parts are arranged on the front end of sleeve, and the front-end face of described oil sealing parts is butted on the ear end face of second gear.This oil sealing parts have been arranged, second gear of high speed rotating and flywheel mutual friction meeting mutually produce impurity and dust is blocked by the oil sealing parts, can not be diffused into the front end of one-way element sleeve, avoided impurity and dust attached on the live axle, thereby avoided these impurity and dust to cause wearing and tearing to sleeve and live axle, even live axle is stuck, cause potential safety hazard, prolonged one-way element even working life motor.
As improvement, the front-end face of described sleeve is provided with the circumferential recess that matches with described oil sealing parts, and described oil sealing parts interference fit is in described groove.
As preferably, described oil sealing parts are seal ring.
Description of drawings
Accompanying drawing the utility model is used for the structural representation of the one-way element of automobile starter.
In the accompanying drawing: 1 live axle, 2 second gears, 3 sleeves, 4 outer covers, 5 star wheels, 6 long springs, 7 first gears, 8 oil sealing parts, 9 short springs, 10 spacing back-up rings.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of one-way element that is used for automobile starter comprises that first gear 7, second gear 2, live axle 1, star wheel 5 and flip sleeve are combined in the sleeve 3 on the live axle 1, are provided with long spring 6 between described sleeve 3 and the live axle 1; Described first gear 7 is fixed on an end of sleeve 3, first gear 7 and star wheel 5 are made an integral body in this example, the other end of described sleeve 3 is installed in the center hole of star wheel 5 one ends through a plurality of rollers and flat spring, and the outer end of described star wheel 5 is provided with outer cover 4, described second gear 2 is fixed on an end of described live axle 1 and is located by spacing back-up ring 10, be provided with short spring 9 between described second gear 2 and the described live axle 1, and the front-end face of the ear end face of described second gear 2 and described sleeve 3 offsets; Be provided with oil sealing parts 8 between described sleeve 3 and the live axle 1, described oil sealing parts 8 are arranged on the front end of sleeve 3, and the front-end face of described oil sealing parts 8 is butted on the ear end face of second gear 2.
The front-end face of described sleeve 3 is provided with the circumferential recess 3.1 that matches with described oil sealing parts 8, and described oil sealing parts 8 interference fit are in described groove 3.1.And described in this example oil sealing parts 8 are seal ring.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation, as: oil sealing parts 8 also can be other Sealings; Deng.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
