[0003] The main function of the hub bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both radial load and axial load; the traditional heavy truck hub bearing is composed of two sets of separate tapered roller bearings. The installation, oiling, sealing and clearance adjustment are all carried out on the automobile production line. This structure makes the assembly difficult, high cost and poor reliability of the automobile factory, and there is no fixed connection mechanism between the two inner rings of the wheel hub bearing. , only rely on the sealing ring to lock in the direction of the outer meridian, and it is easy to scatter during transportation, which brings a lot of trouble to the maintenance and repair of the car. It is necessary to re-clean and oil the bearing and adjust the clearance

Embodiment Construction
[0038] The present invention will be further described below in conjunction with specific embodiment:
[0039] A heavy-duty hub bearing, including an outer ring and a set of opposite inner rings installed in the outer ring, a cage is installed on the outside of the inner ring, a number of tapered rollers are evenly installed in the cage, and a set of opposite inner rings There is a connecting mechanism between them;
[0040] The connecting mechanism includes a connecting part, an annular groove, a limiting ring and a gasket, the connecting part is arranged at the front end of the inner ring, the annular groove is opened at the inner rear end of the connecting part, and the limiting ring is arranged at the inner front end of the connecting part, And located on one side of the annular groove, the gasket is set in the connecting part and is a non-closed ring.
[0041] As an improvement of the above technical solution, several strip-shaped holes are evenly opened on the gasket, a...

The invention discloses a heavy truck hub bearing and a gasket installation device thereof, comprising an outer ring and a set of opposite inner rings installed in the outer ring, a cage is installed on the outside of the inner ring, and several cones are uniformly installed in the cage Shaped rollers, a connecting mechanism is provided between a set of opposite inner rings. The beneficial effect of the present invention is that the wheel hub bearing is developed on the basis of tapered roller bearings, it integrates two sets of bearings, has good assembly, and connects a set of inner rings through gaskets, so that two The inner ring is integrated into one body to prevent easy scattering during transportation, free of clearance adjustment during installation, light in weight, compact in structure, strong in carrying capacity, and is a sealed bearing, filled with grease before leaving the factory, omitting the need for external wheel hubs Sealing; the gasket installation device is installed by absorbing the gasket through the adsorption plate, which effectively reduces manual installation labor, improves installation efficiency, and is convenient and practical.
Description
technical field [0001] The invention relates to the field of hub bearings, in particular to a hub bearing for heavy trucks and a gasket installation device thereof. Background technique [0002] Hub bearings are parts applied to the axles of automobiles to bear weight and provide precise guidance for the rotation of the hubs. They bear both axial loads and radial loads, and are an important part of the load and rotation of automobiles. [0003] The main function of the hub bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both radial load and axial load; the traditional heavy truck hub bearing is composed of two sets of separate tapered roller bearings. The installation, oiling, sealing and clearance adjustment are all carried out on the automobile production line. This structure makes the assembly difficult, high cost and poor reliability of the automobile factory, and there is no fixed connection mechanism between the two inner ...
