Problems solved by technology

[0002] 1. The traditional bearing testing instrument is to place the bearing parts on the instrument and measure them by manually rotating the bearing parts; the heavy and large bearing parts are either in size or the weight exceeds the detection range of the instrument. Even within the detection range, heavy bearing parts are made by The artificial rotation is not stable and the measured value is not accurate
[0003] 2. When measuring the axial distance between the two (ring parts) end faces of the inner and outer rings of the bearing, and the two end faces have tilted swing, the measured value is not accurate

Embodiment 1

[0032] Such as figure 2 As shown, to detect the circularity error (out of roundness) of the ring piece 4: place the ring piece 4 to be tested horizontally during measurement, install an end support 2 on each of the three main body supports 1, place the three end support 2 on The fulcrum is placed in the middle of the end face of the tested ring 4, and three end supports 2 are fixed; a side support 3 is installed on each of the two main body supports 1, and the fulcrums on the two side supports 3 are connected with the tested ring. The outer diameter of 4 is in contact with the two side supports 3; a measuring support 5 is installed on the other main body support 1, and a dial indicator 6 is installed on the lower part of the measuring support 5, and the measuring head of the dial indicator 6 is connected with the measured The outer diameter of the annular part 4 contacts, and the measuring support 5 is fixed; the two side fulcrums are used as force points, and the outer diame...

Embodiment 2

[0034] Such as image 3 As shown, to detect the thickness variation (concentricity) of the annular part 4: place the tested annular part 4 horizontally during measurement, install an end support 2 on each of the three main body supports 1, and place the three end support 2 The fulcrum is placed in the middle of the end face of the tested ring 4, and three end face supports 2 are fixed; a measuring support 5 is installed on one main body support 1, and a side support 3 is installed on the other two main body supports 1, and the two The fulcrum on the side support 3 is in contact with the outer diameter of the tested ring 4, and the two side supports 3 are fixed; a dial indicator 6 is installed on the measuring support 5, and the measuring head of the dial gauge 6 is connected to the tested ring 4 contact with the inner diameter of the measuring support 5; take the two side fulcrums as force points, rotate along the outer diameter of the tested annular piece 4, rotate the main b...

Embodiment 3

[0036] Such as Figure 4 As shown, the verticality of the outer diameter of the test ring 4 relative to the reference end face: when measuring, the ring 4 to be tested is placed horizontally, one end support 2 is installed on each of the three main body supports 1, and the three end support 2 The upper fulcrum is placed in the middle part of the end face of the tested ring part 4, and three end face supports 2 are fixed; a side support part 3 is installed on each of the two main body supports 1, and a measuring support part 5 is installed on one of the main body supports 1, and the two The fulcrum on each side support 3 is in contact with the outer diameter of the tested ring 4, and the two side supports 3 are fixed; a dial indicator 6 is installed on the measuring support 5, and the measuring head of the dial indicator 6 is connected to the tested ring. The outer diameter of 4 is contacted, and the dial indicator 6 is fixed; with the two side fulcrums as force points, the out...

Abstract

The invention discloses a detection apparatus for heavy and large bearings, wherein the apparatus is portable and has multiple functions; therefore, a problem that it is needed to rotate bearing parts manually to carry out measurement during current measurement process of heavy and large bearing parts can be solved. A technical scheme employed in the invention is as follows: the detection apparatus comprises three rectangular or I-shaped main body supports (1), end face supports (2) and side supports (3) and a measurement support (5); besides, the main body supports (1) are uniformly distributed in a radial shape and included angles between the supports are 120 degrees; and the end face supports (2) and side supports (3) and a measurement support (5) are attachedly assembled along the main body supports (1). The detection apparatus for heavy and large bearings can be used to measure a radial error and an axial error. The method comprises: the detection apparatus is arranged on a measured bearing; and the measured bearing is measured by rotating and moving the detection apparatus. According to the invention, the detection apparatus has the following advantages that: detection precision of heavy and large bearings is improved; and manual operation intensity is reduced.

Description

technical field [0001] The invention relates to a bearing testing instrument, in particular to a portable, multifunctional heavy and large bearing (ring piece) testing instrument. Background technique [0002] 1. The traditional bearing testing instrument is to place the bearing parts on the instrument and measure them by manually rotating the bearing parts; the heavy and large bearing parts are either in size or the weight exceeds the detection range of the instrument. Even within the detection range, heavy bearing parts are made by Manual rotation is not stable and the measured value is not accurate. [0003] 2. When measuring the axial distance between the two (ring parts) end faces of the inner and outer rings of the bearing, and when the two end faces are tilted and oscillating, the measured value is not accurate. Contents of the invention [0004] The invention discloses a portable, multi-functional, heavy and large-scale bearing testing device, which measures the p...
