specific Embodiment approach 1

[0012] Specific implementation mode one: combine figure 1 Describe this embodiment. This embodiment includes a housing 1, a left positioning flange 2, a countershaft 3, a lower lubricating oil collector ring 4, a positioning nut 8, a radial carrier 9, a right positioning flange 10, and an axial positioning code 11 , pad iron 12, tension bolt 13, axially loaded end cover 14, end cover pressure plate 15, fastening nut 16, left-handed nut 17 and fixing seat 18, auxiliary shaft 3, positioning nut 8 and left-handed nut 17 from left to right Set coaxially in turn, the under-ring lubricating oil collector ring 4 is set on the auxiliary shaft 3, the left end surface of the under-ring lubricating oil collecting ring 4 is positioned by the auxiliary shaft flange 3-1 on the auxiliary shaft 3, and the left positioning flange 2 is set On the under-ring lubricating oil collector ring 4, the radial carrier 9 is set on the left positioning flange 2, and the left end of the radial carrier 9 pa...

specific Embodiment approach 2

[0014] Specific implementation mode two: combination figure 1 To describe this embodiment, the left end surface of the axial positioning code 11 of this embodiment is provided with a circular groove 11-1. This design makes the left end face of the axial positioning code 11 form an annular end face; because the left end face of the axial positioning code 11 plays the role of contacting and positioning with the right end face of the right positioning flange 10, therefore, the left end of the axial positioning code 11 The processing accuracy of the surface is very high, and it needs to be ground by a grinder. The ring-shaped end surface reduces the contact area of ​​the left end surface of the axial positioning code 11, thereby reducing the amount of grinding debris on the grinder and reducing the processing cost. Other components and connections are the same as those in the first embodiment.

Abstract

A roller bearing simulation test positioning device relates to a roller bearing simulation test device to solve the problem that the roller bearing is easily damaged due to no axial load during the existing roller bearing simulation test. The auxiliary shaft, positioning nut and left-handed nut are set coaxially from left to right in sequence, the under-ring lubricating oil receiver ring is set on the auxiliary shaft, the left positioning flange is set on the under-ring lubricating oil receiver ring, and the radial carrier is set on the left positioning On the flange, the left end of the radial carrier is axially positioned by the left axial positioning flange flange on the left positioning flange, the right positioning flange is installed on the right end surface of the radial carrier, and the radial carrier is set on the In the housing, the tail of the tension bolt is set in the T-shaped slot, and the head of the tension bolt passes through the axial positioning code, the pad iron and the end cover pressure plate to be screwed with the fastening nut. The left end surface of the axial positioning code and the right The right end face of the positioning flange is in contact, and the axially loaded end cover is set on the pad iron. The invention is used for the simulation test of the roller bearing.

Description

technical field [0001] The invention relates to a roller bearing simulation test device, in particular to a roller bearing simulation test positioning device. Background technique [0002] Roller bearing tests need to complete various technical conditions, such as high-speed operation, radial loading, lubrication under the ring, precise axial and radial positioning of the inner and outer rings, etc., which requires designers to, in the process of process equipment design, The technical requirements of various test parameters can be realized in the limited space of the tester. The existing roller bearing simulation test is carried out on the cantilever bearing tester in the laboratory. The roller bearing is installed on the test spindle. If the roller bearing does not bear the load, the outer shell of the roller bearing cannot be positioned relative to the bearing, so that there is an error in the radial loading position of the roller bearing. Sub-bearings are easily damage...
