Among the mounting hole, the bearing is equipped with bearing hole, and the wheel disc periphery is provided with inner rim, the inner rim both sides setting
There are limiting slot, the inner rim periphery to be provided with the outer rim, limiting slot agrees with described in the outer rim, on the left of the wheel disc
It is evenly arranged with big hole around the mounting hole, the wheel disc right side wall is evenly arranged with small sircle hole around the mounting hole, institute
Big hole is stated to be not communicated with the small sircle hole.
As a kind of optimal technical scheme of the utility model, the bearing uses thrust ball bearing.
As a kind of optimal technical scheme of the utility model, the great circle bore dia is slightly larger than the small sircle hole.
As a kind of optimal technical scheme of the utility model, a diameter of 17mm of bearing hole, the installation bore dia
For 34mm.
As a kind of optimal technical scheme of the utility model, the outer rim is made of polyurethane material.
As a kind of optimal technical scheme of the utility model, the wheel disc is made of aluminum alloy materials.
As a kind of optimal technical scheme of the utility model, the outer rim both sides are the shape system of radius 5mm fillets
Make.
Compared with prior art, the utility model has the beneficial effects that：Dual thrust ball bearing built in this polyurethane roller, pole
Big reduces friction of the idler wheel during the work time between installation axle, improves the service life of idler wheel, reduces idler wheel
Repair and replacement frequency reduce cost input for enterprise, improve production efficiency, improve the stability using equipment, ensure equipment
Superperformance, meanwhile, this roller structure is relatively simple, light weight, small, using aluminum alloy materials make wheel disc resistance to compression
Ability is strong, and service life is long, considerably increases the safety of idler wheel, and being capable of pole using the outer rim that polyurethane material makes
Big reduction noise enhances frictional force, the multi abilities of idler wheel is improved, so as to be suitable for more working environments.
