Abstract
The utility model relates to a starting ratchet wheel comprising a ratchet wheel body (1), and ratchet teeth (2) and a ratchet pawl (3) are machined on the front face of the ratchet wheel body (1). The starting ratchet wheel is characterized in that the vertical face angle of the ratchet teeth (2) is 0-3 degrees, the mating surface of the ratchet teeth (2) is 7.7 degrees, and the angle between the upper plane and the bottom plane of the ratchet teeth (2) is 2 degrees. The angle of each combined face of the ratchet teeth (2) is changed to improve combining reliability of the ratchet wheel, so that the ratchet wheel is enabled to mesh and break away more smoothly without the emergence of slipping.
Description
Technical field
The utility model relates to a kind of starting ratchet.Belong to mechanical manufacturing field.
Background technique
In mechanical transmission fields, in order to realize single-direction transmission, ratchet is a kind of mechanical parts commonly used.Generally, with in the transmission system of gear, as realizing single-direction transmission with ratchet, be that certain axle at Transmitted chains adds a ratchet mostly, when the tooth engagement of ratchet and ratchet, driving torque, when direction rotation, the disengaging of the tooth of ratchet and ratchet, axle dallies.Present ratchet adopts the forge hot mode to cast, because the ratchet angle is excessive, skidding appears in ratchet when causing starting, causes starting failure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of starting ratchet is provided, and can prevent from causing starting failure because ratchet skids.
The purpose of this utility model is achieved in that a kind of starting ratchet, comprise the ratchet body, be processed with ratchet and ratchet in the front of described ratchet body, the riser angle of described ratchet is 0 ~ 3 °, the Surface of action angle of described ratchet is 7.7 °, and the upper plane of described ratchet and bottom plane angle are 2 °.
Compared with prior art, the beneficial effects of the utility model are:
The utility model by the angle that changes each junction plane of ratchet improve ratchet in conjunction with reliability, thereby so that the engagement of ratchet with break away from more smooth and easyly, can not occur skidding.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Wherein:
Embodiment
Referring to Fig. 1-Fig. 2, the utility model relates to a kind of starting ratchet, comprise ratchet body 1, front at ratchet body 1 is processed with ratchet 2 and ratchet 3 by the cold closed-die forging technology, the riser angle of described ratchet 2 changes 0 ~ 3 ° into by original 3-8 °, the Surface of action angle of ratchet 2 changes 7.7 ° into by original 0 °, make the combination of ratchet 2 more reliable, throw off more smooth and easy, the upper plane of ratchet 2 and bottom plane angle change 2 ° into by original 0 °, it is larger in conjunction with the degree of depth to allow ratchet 2 have, and has avoided simultaneously the plane to hand over Jie to locate to produce wedge angle.
Claims (1)
1. starting ratchet, comprise ratchet body (1), be processed with ratchet (2) and ratchet (3) in the front of described ratchet body (1), the riser angle that it is characterized in that described ratchet (2) is 0 ~ 3 °, the Surface of action angle of described ratchet (2) is 7.7 °, and the upper plane of described ratchet (2) and bottom plane angle are 2 °.
