Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like figure 1 As shown, the two surfaces of the cuboid oilstone in the length direction are composed of an inwardly concave front surface 3 and an inwardly concave rear surface 5. The two surfaces have the same shape and are symmetrically distributed. The third surface in the length direction of the cuboid oilstone is The upper curved surface 1 with the same radius and the same taper as the tapered roller is concave, the left plane 2, the right plane 4 and the lower plane 6 are all planes, 7 is the projection curve of the front curved surface 3 on the bottom plane, and 8 is the rear curved surface 5 The projection curve on the bottom plane, 9 is the projection curve on the side plane of the A-A sectional view of the upper curved surface 1.

[0028] The diameter of the large end of the tapered roller is 20mm, the diameter of the small en...

Abstract

The invention discloses a super grinding whetstone for cone roller with logarithmic camber. two surfaces of the cuboid whetstone in length direction are composed of symmetrical distributed inwardlydished curved surfaces with same shape; the third surface of the cuboid whetstone in the length direction is a concave curved surface with the radius and taper same to that of the cone roller. The grinding theory says: the workpiece cutting amount is proportional to the contact arc length; therefore, the whetstone structure can be designed according to the cutting amount calculated by the logarithmiccamber curve, and the whetstone can be used for grinding to obtain the workpiece with requested logarithmic camber. the whetstone with the structure needs simple equipments for machining roller camber, is low in cost, and convenient in operation, solves the problems of high difficulty and high cost in logarithmic camber roller machining, has higher engineering value and economic benefit.

Description

technical field [0001] The invention relates to a whetstone for convex roller processing, in particular to a logarithmic convex tapered roller finishing whetstone. Background technique [0002] The finite length of roller-raceway contact results in stress concentrations at the ends of the rollers, reducing the fatigue life of rolling bearings. Roller shape modification design can improve the bearing capacity and fatigue life of rolling bearings, so the convexity selection and convexity calculation of rollers have become one of the key issues. Roller convex types generally include linear type, arc semi-convex type, arc full convex type, corrected linear type and logarithmic type. The logarithmic type is the most ideal roller convex type at present, but its processing difficulty and high cost cannot be widely used in engineering. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a logarithm...
