Background technique
Traditional free wheel device is provided with rolling element and Returnning spring member between rotating component and the interior rotating component that is mated outside, is widely used on automobile, motorcycle and other machinery, to alleviate the wearing and tearing of motor and transmission device, reduces the consumption of fuel oil.The patent No. of Chinese Patent Office authorization bulletin was that ZL952314, name are called " motorcycle transmission of power overrunning clutch " as on March 26th, 1997.This clutch comprises chain wheel, is located at the interior passive coupling flange of chain wheel, is located at ball and Returnning spring between chain wheel and the passive coupling flange, both sides at passive coupling flange also are provided with baffle plate, be contained on the motorcycle and use, when the motorcycle deceleration is slided, can play the effect of fuel-economizing and minimizing component wear.But its structure is complexity comparatively, because the Returnning spring member is housed, breaks away from when not only using slowly, and noise is big when startup or parking, and damages easily.Through investigation and analysis, the main cause that causes free wheel device to damage has: rolling element wearing and tearing, raceway wearing and tearing, spring breakage or follow the string, and wherein because of spring breakage or follow the string and cause the situation of free wheel device damage to be about 90%.
Summary of the invention
The purpose of this utility model provides a kind of novel free wheel device, and its simple in structure, easy manufacturing, simple installation, cost of production are low, break away from during use fast, noise is little, wearing and tearing are little, the life-span is long.
A kind of novel free wheel device described in the utility model, comprise outer rotating component, the interior rotating component that cooperates with outer rotating component inner ring, be connected left gland and the right gland and the attachment screw of outer rotating component both sides or interior rotating component both sides, it is characterized in that on the cylindrical of interior rotating component, being provided with at least the notch of 3 uniform bottom angled, in each notch, be provided with a rolling element, and contact with the inner ring of outer rotating component; Perhaps be provided with 3 notches that uniform bottom is curved at least on the inner ring of rotating component outside, be provided with a rolling element in each notch, and contact with the cylindrical of interior rotating component.The rolling element that is contained in the notch is roller or steel ball.Because the Returnning spring that contacts with rolling element is not set in notch, not only simplify the structure, be convenient to processing and assembling, reduce production costs, and clutch speed is fast, it is little to start and stop noise, and machine members alleviates, and prolong working life.
Described a kind of novel free wheel device is characterized in that being provided with the left wall of uniform notch on the cylindrical of interior rotating component and the angle α of notch bottom surface is 90 °-95 °, and the right wall of notch and the angle β of notch bottom surface are 110 °-120 °; The degree of depth on the notch left side is less than the diameter of rolling element.
Described a kind of novel free wheel device is characterized in that the degree of depth on the left side that the inner ring of rotating component outside is provided with uniform notch less than the degree of depth on the right, and the degree of depth on the right is less than the diameter of rolling element.
Outer rotating component of the present utility model not only can be driven member but also can be driving link, and interior rotating component not only can be driving link but also can be driven member, decides according to different use condition.The utility model manufacturing simple in structure, easy, be convenient to install, cost of production is low, break away from during use fast, noise is little, wearing and tearing are little, the life-span is long.Can be widely used on automobile, motorcycle and other machinery.
