Embodiment 1

[0037] combine figure 1 and figure 2 As shown, the angular contact ball bearing 300 includes a bearing inner ring 320 and a bearing outer ring 310 arranged from inside to outside, and the bearing inner ring 320 and the bearing outer ring 310 are connected by steel balls 330 . Among them, the bearings used to balance the axial thrust are mostly angular contact ball bearings 300 installed in pairs. An inner spacer 321 and an outer spacer 311 are installed between the two angular contact ball bearings 300, that is, two angular contact ball bearings installed in pairs. An inner spacer 321 is installed between the bearing inner rings 320 of the ball bearing 300, and an outer spacer 311 is installed between the bearing outer rings 310 of the two angular contact ball bearings 300, and the outer spacer 311 needs to be measured and adjusted during assembly. , so that the total thrust clearance of the bearing set reaches a qualified range. The traditional assembly sequence of the ang...

Embodiment 2

[0045] The thrust gap measuring and adjusting device of a set of angular contact ball bearings in this implementation has basically the same structure as that of Embodiment 1, further, as figure 2 As shown, the fixing unit 500 in this embodiment includes a fixing base 520 fixed on the top of the inner ring pressure plate 210 and a fixing rod 510 , one end of the fixing rod 510 is connected with the fixing base 520 , and the other end of the fixing rod 510 is connected with the dial indicator 400 . The fixed rod 510 includes a fixed section arranged on the top of the fixed base 520 , wherein the top of the fixed section extends outwards to provide a support section, and the bottom of the support section extends downwards to provide a connecting section, and the bottom of the connecting section is connected to the dial indicator 400 .

[0046] In this embodiment, a detachable connection is adopted between the fixed base 520 and the inner ring pressure plate 210. Specifically, i...

Abstract

The invention discloses a thrust gap measurement and adjustment device of an angular contact ball bearing group, which belongs to the technical field of bearing measurement. The present invention includes an inner ring and an outer ring arranged sequentially from the inside to the outside. The outer ring is sheathed on the outer circumference of the inner ring, wherein the inner ring includes a hollow cylinder, and the upper and lower ends of the hollow cylinder are respectively provided with an inner ring pressure plate and an inner ring base. The inner ring pressure plate and the inner ring base are connected by an inner connecting column, and a dial indicator is arranged on the top of the inner ring pressure plate; The bases are connected by outer connecting columns, and the outer edge of the base of the outer ring is provided with supporting bosses around the circumference, and the supporting bosses extend in a direction away from the pressure ring of the outer ring. The purpose of the present invention is to overcome the disadvantages of complicated and laborious measurement and adjustment of the thrust gap during assembly of the existing angular contact ball bearings or the lack of accurate measurement, to speed up the measurement and adjustment speed, and to improve the accuracy of the measurement results.

Description

technical field [0001] The invention relates to the technical field of bearing measurement, in particular to a thrust gap measurement and adjustment device of an angular contact ball bearing set. Background technique [0002] Angular contact ball bearings can bear radial load and axial load at the same time, and can work at higher speeds. The larger the contact angle, the higher the axial load capacity. The contact angle refers to the angle between the line connecting the contact point of the steel ball and the raceway in the radial plane of the angular contact ball bearing and the vertical line of the bearing axis. Usually high-precision and high-speed bearings take a contact angle of 15°, and the contact angle will increase under the action of axial force. [0003] In power generation enterprises, large axial flow fans and water pumps are the main auxiliary machines of power plants, and bearings are one of the most important components of rotating equipment. In all rotat...
