Abstract

The utility model discloses a tapered roller bearing inner circle raceway inspection frock, including the cup, cup inner chamber lower part is the cylinder, and upper portion is the round platform, and the side of round platform is unanimous with the contained angle of measuring bearing inner circle raceway angle with the bottom surface, and the diameter is greater than inner circle raceway minimum diameter on the round platform, and the diameter equals the inner circle raceway nominal diameter of surveying under the round platform. The utility model discloses directly convert raceway diameter size into height measurement, measuring error is little to easy operation, but short-term test inner circle raceway quality.

Description

Tapered roller bearing inner ring raceway inspection frock

Technical Field

The utility model belongs to the bearing assembly technique especially relates to a tapered roller bearing inner circle raceway inspection frock.

Background

The tapered roller bearing is an interchangeable bearing, the assembly height in the overall dimension is an important dimension parameter, the influencing factors comprise the inner raceway dimension, the outer raceway dimension, the roller dimension and the large flange height dimension, the assembly high tolerance of the conventional tapered roller bearing is more and more strict, the finished product tolerance is also compressed from 0.2 to 0.1, the inner component and the outer ring are required to be interchangeable, the assembly height of the inner component is controlled within the tolerance of 0.05, and once the inner component is assembled, the inner component is not easy to disassemble and assemble, so the inner raceway dimension detection is particularly important.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide one kind and directly convert raceway diameter size into the altitude mixture survey, frock is tested to tapered roller bearing inner circle raceway assembly height that measuring error is little.

The utility model provides a technical scheme that its technical problem adopted: the inspection tool for the inner ring raceway of the tapered roller bearing comprises a cup body, wherein the lower part of an inner cavity of the cup body is a cylinder, the upper part of the inner cavity of the cup body is a round table, the included angle between the side surface and the bottom surface of the round table is consistent with the angle of the inner ring raceway of the measured bearing, the upper diameter of the round table is larger than the minimum diameter of the inner ring raceway, and the lower diameter of the round table is equal to the.

The utility model discloses using-way and principle: when the tool is used, the tool is sleeved on the inner ring, and the tool circular table part is contacted with the inner ring raceway inclined plane. When the detected inner ring raceway is qualified, the pedestal gap between the bottom edge of the tool and the lower edge of the inner ring is a rated gap, and when the detected inner ring raceway is unqualified, the pedestal gap between the bottom edge of the tool and the lower edge of the inner ring is large or falls out.

The utility model has the advantages that: the utility model discloses directly convert raceway diameter size into height measurement, measuring error is little to easy operation, but short-term test inner circle raceway quality.

fig. 2 is a schematic structural view of a sectional view of an operation of a tapered roller bearing inner ring raceway inspection tool.

Detailed Description

Embodiment 1, it is right to combine fig. 1 and fig. 2 below to make the utility model further explain, a tapered roller bearing inner circle raceway inspection frock, including cup 1, cup inner chamber lower part is cylinder 2, and upper portion is round platform 3, and the side of round platform is unanimous with the bearing inner circle raceway angle of surveying with the contained angle of bottom surface, and the diameter is greater than inner circle raceway minimum diameter on the round platform, and the diameter equals the inner circle raceway nominal diameter of surveying under the round platform.

Claims

1. The utility model provides a tapered roller bearing inner circle raceway inspection frock, includes cup (1), its characterized in that: the lower part of the inner cavity of the cup body is a cylinder (2), the upper part of the inner cavity of the cup body is a circular truncated cone (3), the included angle between the side surface and the bottom surface of the circular truncated cone is consistent with the angle of the inner ring raceway of the measured bearing, the upper diameter of the circular truncated cone is larger than the minimum diameter of the inner ring raceway, and the lower diameter of the circular truncated cone is equal to the rated diameter.
