Tapered roller bearing angle and diameter measuring device and calibration device thereof

Abstract

The invention discloses a tapered roller bearing angle and diameter measuring device and a calibration device thereof. Two square calibration blocks are fixed to a T-shaped leveling ruler, and two cylinders which are at a distance of H are arranged on the reference face of each square calibration block; standard measurement blocks are arranged between the cylinders and the leveling ruler, so thatthe angle alpha is determined accurately. The reference face of the T-shaped leveling ruler is adopted to adjust the height differences between the reference faces of leveling devices at the upper ends of the square calibration blocks and the reference face of the leveling ruler to make the height differences identical, so that the influence of the height differences on angular deviation is eliminated. Angle precision errors are controlled within an allowed range of design requirements, and the principle that three lines intersect at one point on the center axis of a bearing is met, so that the purpose is achieved that a tapered roller bearing shows a good motion performance state of pure rolling during usage. The tapered roller bearing angle and diameter measuring device has quite high applicability in the field of outsize tapered roller bearing production, has certain applicability in large tapered roller bearing small-batch pilot production stages, is easy to implement and popularize and has good economic benefits.

Description

Technical field: [0001] The invention relates to a measuring device for tapered roller bearings, in particular to a tapered roller bearing angle and diameter measuring device and a calibration device thereof. Background technique: [0002] At present, in the mechanical assembly industry, in order to improve production efficiency and reduce production costs, some production equipment requirements must meet the conditions of high load, high speed, and large overturning force; while the limit speed of tapered roller bearings is relatively high. And it can be freely combined and matched to bear radial force, axial force, and overturning moment load. It is favored by many designers: the tapered roller bearing can also be designed as a double row or four row tapered roller bearing according to the requirements of the installation conditions. In order to improve the service life of the equipment as much as possible in the limited space. For large batches of tapered roller bearings, sta...

Problems solved by technology

2. The production cycle is long according to the manufacturing process of the inner ring of the bearing

3. In order to ensure that the size and angle error of the cone angle are within the design requirements, it needs to be identified in batches (to meet the point where the three lines intersect on the central axis of the bearing), which increases the production cost
