Bearing block is directly contacted with transmission shaft end cap, is dramatically reduced so direct to end cap shaft hole inner wall when transmission shaft high-speed rotation
Impact and abrasion caused when squeezing.When transmission shaft end cap is in radiation processes, cold-hot air convection agglomerates a large amount of dust, prevents
Dirt net, which plays, prevents dust from entering in transmission shaft end cap.It avoids dust bring from wearing, influences the use environment of transmission shaft.
Preferably, between the end cap flange and end cover body be equipped with it is several be in 70 degree~90 degree dog-ears heat release hole,
The mounting hole being connected with end cap flange is equipped between two adjacent heat release holes.
The heat dissipation performance for improving transmission shaft, extends the service life of transmission shaft and transmission shaft end cap.Mounting hole is used for axis
Hold being fixedly connected between seat and transmission shaft end cap.
Preferably, the bearing block is equipped with several cooling fins to fit with end cap flange, the cooling fin
In serpentine.
The heat that quickening bearing block and transmission shaft end cover distributes, and reduces influence of the temperature raising to transmission shaft.Extension makes
With the period, the consumption of lubricating grease is reduced.
Preferably, the end cap flange flange and bearing block step are in 12 degree~15 degree inclinations angle.
Easy disassembly improves time availability, while also improving positioning and guiding effect.
It is connect preferably, the transmission shaft is sleeved and fixed with bearing block phase bearing-type semicircular ring, and extends bearing
In seat to transmission shaft end cap.
Needs are connected and fixed between transmission shaft and bearing block, protection transmission shaft effectively works.Transmission efficiency is improved, simultaneously
Prolong the service life.Reduce maintenance and replacement cost.
The utility model can reach following effect:
The utility model provides a kind of vehicle transmission hubcap, compared with prior art, has compact-sized, resistance to
Mill, noise abatement, dust-proof, long service life and the good feature of security performance.Nickel-base alloy set is equipped in vehicle transmission hubcap
With abrasive rubber circle, automobile bearing seat is avoided directly to contact with transmission shaft end cap, dramatically reduces transmission shaft high speed in this way and turn
End cap shaft hole inner wall is directly impacted when dynamic and abrasion caused when squeezing.Solve driving force to end cap it is direct impact with
The problem of extruding, reduces the abrasion between bearing block and transmission shaft end cap.
