Abstract

A roller type overrun clutch comprises an outer ring, an inner ring and a roller between the outer ring and the inner ring. The outer surface of the roller is zigzag. The roller type overrun clutch is simple in structure, no auxiliary combined parts are needed, the inner ring and the outer ring have more contact faces by roller with the zigzag outer periphery arc surface, and the problem that an original roller structure with linear surface contact is small in load transmission and easy to slide is solved.

Description

Roller-type overrunning clutch
Technical field
The utility model relates to mechanical transmission technical field, specifically a kind of roller-type overrunning clutch.
Background technique
Along with the development of China's mechanized equipment technology, free wheel device is widely used in mechanical transmission structure with its unique structure, has promoted greatly the development of manufacturing technology.Free wheel device is the conversion for velocity variations or the sense of rotation of driving and driven parts, have the device of clutch function voluntarily, it is arranged on and in mechanical transmission structure, has realized individual event clutch, dynamic braking, the accurate object such as location, stepping intermittent motion, self-locking and check.Roller-type overrunning clutch is divided into two kinds of out star wheel and star-wheels according to the difference of its star-wheel position, and wherein star-wheel is the part with the wedge slot that holds roller.
Although it has advantages of existing multiple clutch separately, can meet preferably the different requirements in different structure, conventional free wheel device, assembly parts is many, make trouble, rate of fault is high, easily skid.The free wheel device of roller type structure because of roller be that circular light face structure is that linear face is combined with interior ring and outer shroud, its frictional force is little very easily there is skidding; The processing of guiding surface is very strict, and phenomenon very easily appears killing in very bad control when oblique angle is too small, when oblique angle is excessive, easily skid; The load transmitting is less, when load is larger, need to design too much roller; Assisted group component has an initial thrust to act on the problems such as roller all the time.
Model utility content
The utility model is in order to overcome above-mentioned defect of the prior art, provides a kind of simple in structure, and roller does not need accessory part, failure rate is low, the roller-type overrunning clutch that bearing load is large.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of roller-type overrunning clutch, comprise outer shroud, interior ring and the roller between outer shroud and interior ring, and the exterior arc surface of described roller is zigzag fashion.
Preferably, described interior ring is star-wheel, and outer shroud is circular ring, and roller is movably fixed in the wedge slot of star-wheel.
Preferably, described outer shroud is star-wheel, and outer shroud is circular ring, and roller is movably fixed in the wedge slot of star-wheel.
The roller clutch providing of the present utility model, have simple in structure, do not need assisted group component, exterior arc surface is that jagged roller makes interior ring and outer shroud have more surface of contact, has solved the problem of the little and easy slip of the transfer charge of linear face contact of original roller construction.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with drawings and Examples, further illustrate.
Fig. 1 is the roller construction schematic diagram of roller-type overrunning clutch.
Fig. 2 is that interior ring is the roller-type overrunning clutch separated state schematic diagram of star-wheel.
Fig. 3 is that interior ring is the roller-type overrunning clutch working state schematic representation of star-wheel.
Fig. 4 is that outer shroud is the roller-type overrunning clutch separated state schematic diagram of star-wheel.
Fig. 5 is that outer shroud is the roller-type overrunning clutch working state schematic representation of star-wheel.
Embodiment
Embodiment one: a kind of roller-type overrunning clutch, comprise outer shroud, interior ring and the roller between outer shroud and interior ring, and the exterior arc surface of described roller is zigzag fashion, wherein roller construction is as shown in Figure 1.
Embodiment two: as shown in Figures 2 and 3, a kind of roller-type overrunning clutch, comprises circular outer shroud 1, star-wheel 2, is positioned at wedge slot 3 and roller 4 on star-wheel 2, and the quantity of wedge slot is 3 ~ 10, and roller 4 is movably fixed in wedge slot 3.
When star-wheel 2 turns clockwise, as shown in Figure 2, roller 4 is rolled into the spacious part of wedge slot 3, and clutch is in separated state, and outer shroud 1 is not worked.When star-wheel 2 is rotated counterclockwise, as shown in Figure 3, roller 4 produces in the other direction and moves with star-wheel 2, by star-wheel 2 guide surfaces, makes roller 4 and outer shroud 1 close contact, thereby drives outer shroud 1 to rotate together.When star-wheel 2 all turns round by counter clockwise direction in the same way with outer shroud 1, according to relative motion principle, when the rotating speed of outer shroud 1 is less than the rotating speed of star-wheel 2, clutch is in bonding state; When the rotating speed of outer shroud 1 is greater than the rotating speed of star-wheel 2, clutch is in separated state.
Embodiment three: as shown in Figure 4 and Figure 5, a kind of roller-type overrunning clutch, comprises star-wheel 5, circular interior ring 6, is positioned at wedge slot 3 and roller 4 on star-wheel 2, and the quantity of wedge slot is 3 ~ 10, and roller 4 is movably fixed in wedge slot 3.
When star-wheel 5 turns clockwise, as shown in Figure 4, roller 4 is rolled into the spacious part of wedge slot 3, and clutch is in separated state, and interior ring 6 is not worked.When star-wheel 5 is rotated counterclockwise, as shown in Figure 5, roller 4 produces in the other direction and moves with star-wheel 5, by star-wheel 5 guide surfaces, makes roller 4 and interior ring 6 close contacts, thus ring 6 rotation together in driving.When star-wheel 5 all turns round by counter clockwise direction in the same way with interior ring 6, according to relative motion principle, when the rotating speed of interior ring 6 is less than the rotating speed of star-wheel 5, clutch is in bonding state; When the rotating speed of interior ring 6 is greater than the rotating speed of star-wheel 5, clutch is in separated state.

Claims (3)
