Abstract
The invention provides an automatic tensioning wheel bearing of a belt. The bearing comprises a fixing frame, a core shaft, a rolling bearing, an eccentric wheel and a shell, wherein the shell is arranged on the eccentric wheel through the rolling bearing, the eccentric wheel is arranged on the core shaft through a bushing; one end of the core shaft is fixed on the fixing frame, the other end of the core shaft is provided with a gasket which is used for preventing the eccentric wheel from falling off from the core shaft; a spring sleeve base is arranged between the eccentric wheel and the fixing frame, and is provided with a spiral spring; the outer edge of the eccentric wheel is provided with a lug; the lug and the inner edge of the eccentric wheel form a groove. The automatic tensioning wheel bearing is reasonable in design, simple in structure, stable in work, low in noise, convenient to maintain, durable in usage, long in service life and high in economic benefit.
Description
Technical field
The present invention relates to field of bearings, be specifically related to belt auto-tensioning wheel bearing.
Background technique
Automatic tensioner is as one of important accessory of motor, be widely used step by step at present, its Main Function is exactly the tension force that keeps belt, thereby make the more effective work of motor, tension force is as the key function of belt drive system, can fix or auto-tensioning wheel bearing is realized by use, while using fixed tensioning wheel, the dimensional changes producing due to the elongation of belt in life span and wearing and tearing and motor fuselage and the different thermal expansion coefficient of belt, make motor tension force in operation process very unstable, if tension force is excessive, drive unit is easy to produce noise and belt life shortens, if tension force is too small, the easy generation of vibration noise of belt, and belt is easy to wrinkling, wearing and tearing, thereby the lost of life, because the shortcoming of prior art, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, with it, be engaged in this industry working experience for many years, unstable for belt tension force in operation process in motor car engine actuated by cams, easily produce the shortcoming of having vibrated noise, and then develop belt auto-tensioning wheel bearing, utilize simple design, reduced the fluctuation of Idle wheel, tension force is controlled in rational scope, vibration and noise have been reduced, can make the present invention reach simple in structure, easy to manufacture, easy to operate, use safety, consuming cost is low, the effect that working efficiency is high.
Summary of the invention
Technical problem to be solved by this invention is to provide belt auto-tensioning wheel bearing, reasonable in design, simple in structure, and working stability produces noise little, maintains easily, durable in use, long service life, and economic benefit is high.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: belt auto-tensioning wheel bearing, comprise fixing frame, mandrel, rolling bearing, eccentric wheel, shell, described shell is arranged on eccentric wheel by rolling bearing, described eccentric wheel is arranged on mandrel by lining, described mandrel one end is fixed on fixing frame, the other end is provided with and prevents that eccentric wheel from departing from the pad of mandrel, between eccentric wheel and fixing frame, be provided with spring block set, described spring block set is provided with helical spring, described eccentric wheel outer rim is provided with a projection, described projection and eccentric wheel inner edge form groove.
As preferably, described helical spring one end is fixed on fixing frame, and the other end is arranged in groove.By adopting this set, reduced widely the fluctuation of Idle wheel, tension force is controlled in rational scope, reduced vibration and noise, reasonable in design, simple in structure, compact, easy to manufacture, working effect is obvious.
As preferably, described fixing frame is provided with opening slot, and described projection is embedded in opening slot and forms sworn followers' piece restriction eccentric wheel around the pendulum angle of mandrel.By adopting this set, to eccentric wheel, can play good position-limiting action.
Beneficial effect:
The present invention adopts technique scheme that belt auto-tensioning wheel bearing is provided, and has made up deficiency of the prior art, has reduced noise, extended working life, improved economic benefit, reasonable in design, simple in structure, working stability, generation noise is little, maintains easily, durable in use, long service life, economic benefit is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
