Abstract
The utility model relates to a speed reducing ratchet wheel type one-way clutch. A gear shaft is fixedly connected on one end portion of a hollow pipe, a ratchet wheel sleeve capable of sliding in the axial direction of the hollow pipe is sleeved on the outer circumference of the hollow pipe, a gear ring is sleeved on the outer circumference of the hollow pipe, transmission teeth are machined on the outer circumference of the gear ring, a block ring is fixedly arranged on one end portion of the inner circumference of the gear ring, a ratchet wheel plate is fixedly arranged on the other end portion of the inner circumference of the gear ring, and plane meshing type ratchet wheel mechanisms are arranged on the opposite end faces of the ratchet wheel plate and the ratchet wheel sleeve. The plane meshing type ratchet wheel mechanisms are arranged between the gear ring and the hollow pipe, two plane ratchet wheels are always in a meshing state under the action of spring thrust, torque can be reliably transmitted when the gear ring rotates in a forward direction, and the phenomenon of slipping cannot occur. When an engine oppositely pull the gear shaft to operate in an overturn mode, ratchet wheel teeth are automatically separated, the torque is not transmitted, and the service life of the one-way clutch can be effectively guaranteed to reach more than 35,000 times.
Description
Technical field
The utility model relates to a kind of automobile starter with unidirectional delivery power reverse skid single-way speed-reducing device, specifically a kind of deceleration Ratcheting one-way clutch.
Background technique
At present, production and the application of deceleration roller type automobile one-way clutch device have been arranged both at home and abroad, its principle is to be provided with the curved surface chute in the gear ring, by the roller wedging, the transmission of power on the gear ring to the tooth axle.Observed discovery in several years, and be used on the smaller 12V actuating motor of power reliablely, often skid but be used on the 24V actuating motor, working life is short, and the ordinary test life-span is all less than 20000 times.And actuating motor GB life test requires more than 35000 times, and up to the present domestic production one-way element producer does not all also have actual addressing this problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of long service life, simple in structure, service-strong deceleration Ratcheting one-way clutch are provided.
The technological scheme that provides according to the utility model, described deceleration Ratcheting one-way clutch, comprise hollow tubular, back-up ring, gear ring, ratchet sleeve, the ratchet cover plate and tooth axle, end at hollow tubular slidely connects the tooth axle, being socketed with at the cylindrical of hollow tubular can be along the in axial sliding ratchet sleeve of hollow tubular, cylindrical at hollow tubular is socketed with gear ring, cylindrical at gear ring is processed with driving cog, inner circle one end at gear ring is fixed with back-up ring, inner circle the other end at gear ring is fixed with the ratchet cover plate, is provided with the engagement type ratchet mechanism in plane at the opposing end surface of the ratchet cover plate and ratchet sleeve.
Be provided with spring between back-up ring and ratchet sleeve, an end and the back-up ring of spring offset, and the other end and the ratchet sleeve of spring offset.
Described ratchet sleeve is connected with hollow tubular by oblique spline.
The utility model is equipped with the engagement type ratchet mechanism in plane between gear ring and hollow tubular, two plane ratchets are in engagement all the time under the effect of spring thrust, can be when gear ring be rotated in the forward reliable delivery moment, can not produce skidding; Drag the tooth axle to surmount when running hook tooth to throw off voluntarily motor is counter, carry-over moment can not guarantee effectively that reach more than 35000 times the working life of overrunning clutch.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this deceleration Ratcheting one-way clutch, comprise hollow tubular 1, back-up ring 2, gear ring 3, ratchet sleeve 5, the ratchet cover plate 7 and tooth axle 8, end at hollow tubular 1 slidely connects tooth axle 8, being socketed with at the cylindrical of hollow tubular 1 can be along the in axial sliding ratchet sleeve 5 of hollow tubular 1, cylindrical at hollow tubular 1 is socketed with gear ring 3, cylindrical at gear ring 3 is processed with driving cog, inner circle one end at gear ring 3 is fixed with back-up ring 2, inner circle the other end at gear ring 3 is fixed with the ratchet cover plate 7, is provided with the engagement type ratchet mechanism in plane at the opposing end surface of the ratchet cover plate 7 and ratchet sleeve 5.
Be provided with spring 4 between back-up ring 2 and ratchet sleeve 5, an end and the back-up ring 2 of spring 4 offset, and the other end of spring 4 and ratchet sleeve 5 offset.
Described ratchet sleeve 5 is connected with hollow tubular 1 by oblique spline.
With ratchet sleeve 5 hook tooth that matches is arranged at the ratchet cover plate 7, consist of the engagement type ratchet mechanism in plane, back-up ring 2 all is fixed on the inner circle of gear ring 3 with the ratchet cover plate 7, and ratchet sleeve 5 cooperates and can move axially with hollow tubular 1, and ratchet sleeve 5 is in engagement with the ratchet cover plate 7 under the thrust of spring 4.
Working principle of the present utility model is: the engagement type ratchet mechanism in plane is housed between gear ring 3 and the hollow tubular 1, ratchet sleeve 5 is in engagement all the time with 7 liang of plane ratchets of the ratchet cover plate under the effect of spring 4 thrusts, gear ring 3 is delivered to moment of torsion on the tooth axle 8 by pin 6, the ratchet cover plate 7, ratchet sleeve 5, hollow tubular 1, thereby plays the effect of piloting engine.Ratchet sleeve 5 is connected with hollow tubular 1 by oblique spline and can be along the moving axially of hollow tubular 1, when motor is anti-when dragging tooth axle 8 to surmount running, and ratchet sleeve 5 and the ratchet cover plate 7 automatic trips cunning of performing fighting.When static, automatically reset at the thrust bottom ratchet wheel of spring 4 cover 5.
