Vibration measuring instrument for super-large or super-heavy bearing

Abstract

Disclosed is a vibration measuring instrument for a super-large or super-heavy bearing. The vibration measuring instrument comprises a measuring device, an axial reinforcing device, a vehicle conveying device, and radial reinforcing devices. One end of a main shaft penetrates a through hole in a supporting plate of the measuring device, a pedestal of the measuring device is fixed to one end of a platform, and the other end of the main shaft fixes a to-be-measured bearing through a mandrel. The radial reinforcing devices are placed on the left side and the right side of the to-be-measured bearing respectively, and cylinder support plates on the radial reinforcing devices clamp the to-be-measured bearing in a reinforcing manner. The axial reinforcing device is arranged on the other end of the platform. With the center of the mandrel being a reference, a first contact on the axial reinforcing device is in alignment with the outer ring of the to-be-measured bearing, and a second contact is in alignment with the inner ring of the to-be-measured bearing. The vehicle conveying device is arranged below the to-be-measured bearing, slides on a track formed by an outer baffle plate, an inner baffle plate with a slideway, a bearing connection shaft and a bearing, and is in cooperation with the to-be-measured bearing. The to-be-measured bearing is placed on the vehicle conveying device. Both a large-scale and a heavy bearing can be measured on the same instrument.

Description

technical field [0001] The present invention relates to a method and device for measuring the vibration of extra-large and heavy-duty bearings, in particular to a new measuring device for extra-large cylindrical roller bearings, a force device for extra-large bearings, a trolley transport device for extra-large and heavy-duty bearings, and automatic sensor upgrades device. Background technique [0002] The maximum bearing outer diameter range detected by traditional large-scale bearing vibration measuring instruments is between 150 mm and 260 mm, and whether the detection method is domestic or foreign, for extra-large (260 mm < outer diameter ≤ 500 mm) ≤ weight ≤ 800 Newton) bearings do not have a good vibration detection method, and the extra-large and heavy-duty bearing vibration measuring instrument of the present invention solves this problem well. The driving system of the extra-large and heavy-duty bearing vibration measuring instrument adopts the oil static pressu...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the problem of difficult detection of extra-large and heavy-duty bearings, the problem of how the drive system can bear a large bearing capacity, the problem that the rollers of cylindrical roller bearings are not easy to rotate and easily damage the inner ring, outer ring and rolling bodies during the measurement process, and the sensor The contact scratches the outer circle of the bearing
