Abstract
A kind of high water proof and dust proof tension pulley, comprise belt pulley and the support plate being connected belt pulley, described belt pulley is connected with support plate by axle bolt, and be provided with bearing between belt pulley and axle bolt, bearing in described belt pulley is provided with mazy type dust cover near support plate side, and opposite side is provided with the blind head dust cover with the inner ring interference fit of belt pulley; The utility model increases mazy type dust cover and blind head dust cover respectively at belt pulley two ends, and the inner ring interference fit of blind head dust cover and belt pulley, dust, sewage, mud are stopped to the attack of bearing, strengthen belt pulley to the defensive ability/resistance ability of dust, sewage, mud, thus effectively improve the working environment of belt tension wheel bearing, improve its working life.
Description
Technical field
The utility model relates to a kind of tension pulley, and particularly the high water proof and dust proof tension pulley of one, belongs to mechanical transmission field of accessories.
Background technique
In vehicle transmission, belt transmission application widely, in order to ensure that reliable transmission is effective, being installed tension pulley and being necessary very much.Bearing is the key element in Idle wheel working life working life, especially at engineering and mining machinery diesel engine tension pulley, these tension pulleys are in daily using process, working environment becomes very severe relative to passenger car, usually dust can be subject to, sewage, the attacks such as mud, and the dust-proof of traditional belt tension wheel bearing is that clearance type is dust-proof, can only prevent solid particle from attacking, to dust, sewage, the defence capability of mud is poor, under such operating mode, the bearing of tension pulley is made to be easy to by dust, sewage, mud is attacked, bearing grease lost efficacy very soon, tension pulley inefficacy ratio is finally caused greatly to increase.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, it is strong that the utility model provides a kind of defence capability to dust, sewage, mud, effective working environment improving belt tension wheel bearing, improves the high water proof and dust proof tension pulley in its working life.
The utility model solves the technological scheme that its technical problem adopts: a kind of high water proof and dust proof tension pulley, comprise belt pulley and the support plate being connected belt pulley, described belt pulley is connected with support plate by axle bolt, and be provided with bearing between belt pulley and axle bolt, bearing in described belt pulley is provided with mazy type dust cover near support plate side, and opposite side is provided with the blind head dust cover with the inner ring interference fit of belt pulley.
As preferably, described support plate is provided with spring supporting cover and central axle sleeve, is provided with spring, is provided with spring backing plate in described spring in described spring supporting cover, is provided with packing ring between described spring supporting cover and support plate.
As preferably, described support plate end face is provided with end cap, and end cap and spring supporting cover, central axle sleeve three are concentric, and is provided with butterfly spring seat in the groove that formed between overlapping of end cap and spring supporting, is provided with butterfly spring in described butterfly spring seat.
As preferably, described central axle sleeve is provided with lasso.
As preferably, between described packing ring and spring supporting overlap, be provided with flat board.
The utility model increases mazy type dust cover and blind head dust cover respectively at belt pulley two ends, and the inner ring interference fit of blind head dust cover and belt pulley, dust, sewage, mud are stopped to the attack of bearing, strengthen belt pulley to the defensive ability/resistance ability of dust, sewage, mud, thus effectively improve the working environment of belt tension wheel bearing, improve its working life.
