Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] as attached figure 1 Shown: a tapered roller bearing for gears, including an inner ring 1, a rolling element group 2 and a cage 3, and a toothed outer ring 4 of the bearing with a gear 41 formed integrally around the outside.

[0017] The radial distance between the large end of the inner hole 42 of the toothed outer ring 4 of the bearing and the dedendum circle 43 of the gear 41 is three times the modulus of the gear 41 .

[0018] The material of the toothed outer ring 4 of the bearing is GCr15.

[0019] The hardness at the inner hole 42 is HRC63; the hardness at the gear 41 is HRC50. It can meet the different working requirements of the inner hole of the toothed outer ring of the bearing and the hardness of the gear at the same time.

[0020] A heat treatment method for a bearing toothed outer ring 4, wherein the outer side of the bearing toothed outer ring...

Abstract

The invention relates to the field of manufacture of gears and bearings, and aims at providing a heat treatment method for a gear tapered roller bearing and a bearing toothed outer ring. The gear tapered roller bearing comprises an inner ring, a roller group and a retainer, and the gear tapered roller bearing also comprises the gear bearing toothed outer ring integrally formed at the outer side in a surrounding way. The bearing and the gear of the gear tapered roller bearing are integrally formed, so that the gear tapered roller bearing is relatively high in bearing capacity and power density, and enables the volume of a gear case to be relatively small. The heat treatment method for the bearing outer ring made of a material GCr15 is capable of satisfying the working requirement that the bearing toothed outer ring possesses good toughness while possessing high strength and hardness.

Description

technical field [0001] The invention relates to the field of gear and bearing manufacturing, in particular to a heat treatment method for a gear tapered roller bearing and a toothed outer ring of the bearing. Background technique [0002] The gearbox has bearings and gears. Many gearboxes with high rated power use tapered roller bearings. Traditional gearboxes are not integrated with bearings and gears. When the gear reduction ratio is large, the bearing capacity and power density are relatively large. Therefore, a tapered roller bearing and a tapered roller bearing for gears with relatively high bearing capacity and power density make the volume of the gearbox relatively small. The heat treatment method of the toothed outer ring of the bearing has become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the current traditional gearboxes that the bearings and gears are not integrally...
