Description

Technical Field

[0001] The utility model relates to the field of bearing detection, and particularly relates to a detection mechanism for the disengaging force of angular contact bearings. Background Technique

[0002] An angular contact bearing is a special ball bearing. The connecting line of the contact points between the steel balls and the inner and outer rings forms an angle with the radial direction. An angular contact bearing consists of an inner ring, an outer ring, and rolling elements (usually steel balls or steel cylinders). The rolling elements are located between the inner ring and the outer ring and transmit loads and reduce friction through rolling. The working principle of an angular contact bearing is based on rolling friction. When a load acts on the bearing, the rolling elements start to roll between the inner ring and the outer ring and simultaneously bear the action of axial and radial forces. Due to the existence of rolling friction, angular contact bearings have low friction and high efficiency and are suitable for high-speed and high-load applications.

[0003] The detection of the disengaging force of angular contact bearings is an important link to ensure the performance and operation stability of bearings. The main purpose of the detection of the disengaging force of angular contact bearings is to evaluate the stability of the bearings under the action of external forces. If precise measurement under laboratory conditions is used for the detection of the disengaging force, the cost is too high and the efficiency is low. It is difficult to judge the actual disengaging force of angular contact bearings through the visual inspection and tactile feeling of operators. Therefore, a detection mechanism for the disengaging force of angular contact bearings is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detection mechanism for the disengaging force of angular contact bearings to solve the problems raised in the above background technique: if precise measurement under laboratory conditions is used for the detection of the disengaging force, the cost is too high and the efficiency is low, and it is difficult to judge the actual disengaging force of angular contact bearings through the visual inspection and tactile feeling of operators.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a detection mechanism for the disengaging force of angular contact bearings, including an installation sleeve housing, characterized in that: a support base is fixedly connected between the bottoms of the installation sleeve housing, a force application component is installed at the center of the support base, an angular contact bearing body is placed at the output end of the force application component, a force measurement component is arranged at the top of the inner wall of the installation sleeve housing, the force measurement component is located directly above the angular contact bearing body, a non-contact displacement sensor is installed on the upper surface of the installation sleeve housing, and the detection end of the non-contact displacement sensor extends into the force measurement component.

[0006] Preferably, the force application component includes a stroke cylinder, and a material placement disc is fixedly connected to the output end of the stroke cylinder.

[0007] Preferably, a material placement through groove is arranged on the upper surface of the material placement disc, a light sensor switch is installed at the edge of the inner wall of the material placement through groove, and the angular contact bearing body is placed inside the material placement through groove.

[0008] Preferably, the force measuring component includes a force measuring sleeve, which is adapted to the outer ring of the angular contact bearing body in size and is located directly above the outer ring of the angular contact bearing body.

[0009] Preferably, the force measuring sleeve is fixedly connected to the top of the inner wall of the mounting housing, and an installation through groove is provided at the bottom of one side of the force measuring sleeve.

[0010] Preferably, a pressure sensor is installed between the inner walls of the installation through groove, the detection end of the pressure sensor is at the same horizontal plane as the lower surface of the force measuring sleeve, and the detection end of the non-contact displacement sensor extends into the force measuring sleeve.

[0011] The technical effects and advantages of the present utility model are as follows:

[0012] (1) In this device, the force measuring sleeve is in contact with the outer ring of the angular contact bearing body. When a large disengagement force is applied by the force applying component, the inner ring of the angular contact bearing body is separated from the outer ring of the angular contact bearing body to a large extent. At this time, the disengagement amount of the inner ring of the angular contact bearing body can be detected by the non-contact displacement sensor, and the pressure between the outer ring of the angular contact bearing body and the force measuring sleeve can be detected by the pressure sensor, so as to measure the disengagement force of the angular contact bearing body. This device does not require laboratory conditions, has a low equipment cost, and can measure the disengagement force of the angular contact bearing, solving the problems that if the disengagement force is detected by precise measurement under laboratory conditions, the cost is too high and the efficiency is low, and it is difficult to judge the actual disengagement force of the angular contact bearing by the operator's vision and touch inspection.
