Ball purchases auto parts and components, actively carries out centralized purchasing, and this includes the production of tensioning wheel to domestic outstanding Automobile Parts Industry
Enterprise brings the bigger market opportunity, also, China's car ownership is increasing with the increase of automobile sales volume, to open
Bearing up pulley provides wide market.Conventional engines belt tensioner configurations use plastic bushing or oilless bearing directly and center
Axle friction, in prolonged operation, it may occur that abrasion, cause stretcher to produce abnormal sound, clamping stagnation, belt fracture etc. failure,
And higher and higher engine life requirement at present can not be met.
The content of the invention
The purpose of this utility model is solve the deficiencies in the prior art, the utility model provide it is a kind of it is simple in construction,
High abrasion tension pulley reasonable in design, friction area is big, dust-proof anti-mud effect is good.
Technical scheme is used by the utility model solves its technical problem：A kind of high abrasion tension pulley, including
The support plate of belt pulley and connection belt pulley, is arranged with spring in the support plate, the outside of the support plate is provided with bullet by central shaft
Spring support set, is provided with bushing between the support plate and spring supporting set, inside and outside the bushing face respectively with support plate and bullet
Spring support set is in contact, and the outer end of the bushing is provided with bushing rib, and the outer ring of the support plate at bushing rib relative to being provided with
Support plate rib, the support plate rib are covered in the outside of bushing rib.
Preferably, the support plate is being provided with end cap away from spring supporting set side, formed between the support plate and end cap
One cavity volume.
Preferably, the central shaft is arranged on support plate, one end of the central shaft is connected with spring supporting set, separately
One end is connected through cavity volume with end cap.
Preferably, the spring housing is on the central shaft, and the both ends of spring respectively the inwall with support plate, in end cap
Wall abuts against.
Preferably, the belt pulley is arranged on support plate by bolt, and bolt is in side of the belt pulley away from support plate
Provided with dust cap.
Preferably, the bushing is plastic material, and the outer surface of bushing is rubbed muscle 82 provided with increasing.
The utility model sets the bushing of plastic material, bushing and support plate, spring branch between support plate and spring supporting set
Support set directly contacts generation friction, increases friction area, reduces the frictional force of unit area, and set bushing in the outer end of bushing
Rib, the support plate rib being covered on the outside of bushing rib is set in the outer ring of support plate, sealing effectiveness is increased, effectively prevents dust
Or mud engaging friction face；The utility model also has the advantages that simple in construction, reasonable in design.
