Abstract
The utility model discloses a tension pulley for a fan belt. The tension pulley comprises a belt pulley (1) and a support plate (2) connected with the belt pulley (1), wherein a central hole (7) is formed on the support plate (2); a spring support sleeve (3) is mounted in the central hole (7); a spring (4) is mounted between the support plate (2) and the spring support sleeve (3); a rubber sleeve (5) is sleeved outside the spring (4); a pin (6) is also arranged on the spring support sleeve (3); a plastic gasket (8) is mounted between the spring (4) and the support plate (2); a spring pad seat (9) is mounted between the spring (4) and the spring support sleeve (3); and a snap ring (10) is arranged on the spring pad seat (9). The utility model has the advantages that the damping ratio is increased; the noise and the abrasion to parts are reduced; the service life of the tension pulley is prolonged; and as the pin arranged on the spring support sleeve is formed through die casting during the manufacture of the tension pulley, the strength of the tension pulley is greatly enhanced.
Description
Technical field
The utility model relates to a kind of mechanical transmission field of accessories, particularly a kind of fan belt idler.
Background technique
In the mechanical transmission, belt transmission is most widely used, particularly in car transmissions, the belt transmission that is used to drive radiation fan often is under the situation of high temperature high load, especially need installation tensioner effective to guarantee reliable transmission, but traditional tension device is directly realized the swing or the rotation of belt pulley by spring, it is bigger to rub, transmission efficiency is lower, the wearing and tearing of component are bigger, and noise is bigger, and what be generally used for the fixed tensioning wheel simultaneously is common bolt or pin, under the high temperature high load, very easily fractureed.
The model utility content
The purpose of this utility model promptly is to overcome the shortcoming of existing fan belt idler, and a kind of fan belt idler is provided, and can increase damping ratio, in use reduces noise and wearing and tearing, improves the stability of Idle wheel simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of fan belt idler, the support plate that comprises belt pulley and connecting belt wheel, on the described support plate center hole is arranged, the spring supporting sleeve is installed in the center hole, mounting spring between support plate and spring supporting sleeve, the spring skin is overlapping rubber sleeve, also is provided with pin on the spring supporting sleeve.
Between described spring and support plate plastic washer is installed, between spring and spring supporting sleeve the spring base is installed, on the spring base snap ring is arranged.
Between described support plate and the spring supporting sleeve lasso has been installed also.
Be provided with bearing between described belt pulley and support plate, the belt pulley end face connects with dust cover and passes through bolt.
The beneficial effects of the utility model show: the skin at spring has overlapped rubber sleeve, simultaneously, spring and support plate, spring supporting sleeve have been installed plastic washer and snap ring respectively, increased damping ratio, the wearing and tearing of noise and part have been reduced, improved the working life of Idle wheel, the pin that is provided with on spring supporting sleeve die casting when the Mold Making Idle wheel forms, and has greatly increased the intensity of Idle wheel.
