Description
Technical field
The present invention relates to a kind of tension pulley, more particularly to a kind of high abrasion tension pulley.
Background technology
In recent years, domestic automobile volume of production and marketing increases year by year, domestic market is consequently increased the demand of tensioning wheel.I
State's automobile market has turned into the part in world car market, and during automobile industry globalizes, vehicle enterprise is towards complete
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
It is an object of the invention to solve the deficiencies in the prior art, the invention provides it is a kind of it is simple in construction, reasonable in design,
The high abrasion tension pulley that friction area is big, dust-proof anti-mud effect is good.
The technical solution adopted for the present invention to solve the technical problems is：A kind of high abrasion tension pulley, including belt
The support plate of belt pulley is taken turns and connected, is arranged with spring in the support plate, the outside of the support plate is provided with spring branch by central shaft
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 spring branch
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 is relative to being provided with support plate at bushing rib
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 present invention sets the bushing of plastic material, bushing and support plate, spring supporting set between support plate and spring supporting set
Directly contact produces friction, increases friction area, reduces the frictional force of unit area, and set bushing to keep off in the outer end of bushing
Side, set in the outer ring of support plate and be covered in support plate rib on the outside of bushing rib, increase sealing effectiveness, effectively prevent dust or
Person's mud engaging friction face；The present invention also has the advantages that simple in construction, reasonable in design.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the embodiment of the present invention；
Fig. 2 is the explosive view of the embodiment of the present invention.
