Abstract
The utility model relates to a novel overrun clutch ratchet, wherein an alloy liner plate is embedded in a dovetail groove on an engagement surface below a ratchet roller. The engagement surface of the alloy liner plate and the roller has high hardness, is not easy to wear and has long service life; and the alloy liner plate is embedded in the dovetail groove, therefore the alloy liner plate can be taken out for maintenance in case of the abrasion occurring on the engagement surface of the alloy liner plate and the roller.
Description
Technical field
The utility model relates to a kind of free wheel device ratchet, and particularly a kind of novel free wheel device ratchet belongs to the mechanical parts technical field.
Background technique
The free wheel device ratchet is component commonly used in the machinery, so far, often the problem that occurs cisco unity malfunction at work because the conjunction surface below the free wheel device ratchet roller weares and teares easily, at present, conjunction surface below the free wheel device ratchet roller is in case wearing and tearing, easy-maintaining not, and working life is short, cause passive in the work like this, easily.
Summary of the invention
The purpose of this utility model is: a kind of novel free wheel device ratchet is provided, and it can effectively improve and agree with wearing and tearing and the problem of easy-maintaining not below the free wheel device ratchet roller, therefore, can bring the facility in the work.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: a kind of novel free wheel device ratchet, it is to be embedded with the alloy backing plate in the dovetail groove on the conjunction surface below the ratchet roller, because the conjunction surface hardness of alloy backing plate and roller is difficult for wear-resisting greatly and long service life, because alloy backing plate and dovetail groove are embedded modes, so even the conjunction surface of alloy backing plate and roller wear problem occurs and can take out the repair and replacement of alloy backing plate.
Beneficial effect, a kind of novel free wheel device ratchet of the utility model, the hardness of the conjunction surface of its alloy backing plate and roller is difficult for wear-resisting greatly, because alloy backing plate and dovetail groove are the repair and replacement so that take out of embedded mode institute, so, its long service life, be convenient to the maintenance and using effect is good.
Description of drawings
Below in conjunction with accompanying drawing structure of the present utility model is described further.
Fig. 1 is a structural principle schematic representation of the present utility model.
Shown in the figure: 1, ratchet; 2, sleeve; 3, roller; 4, push rod; 5, spring; 6, alloy backing plate; 7, ratchet wheel body.
Embodiment
Be embedded with alloy backing plate (6) in the dovetail groove on the conjunction surface below ratchet (1) roller (3), because alloy backing plate (6) is difficult for wear-resisting greatly and long service life with the conjunction surface hardness of roller (3), because alloy backing plate (6) is an embedded mode with dovetail groove, so even the conjunction surface of alloy backing plate (6) and roller (3) wear problem occurs and can take out alloy backing plate (6) repair and replacement.
Claims (1)
1. a novel free wheel device ratchet is characterized in that: be embedded with alloy backing plate (6) in the dovetail groove on the conjunction surface below ratchet (1) roller (3).
