Abstract
Description
Technical Field
[0001] The utility model relates to a CT machine bearing locking assembly which is easy to install. Background Art
[0002] Bearings are essential components for the rotational support of mechanical bodies and are widely used in all aspects of our production and daily lives. Due to their wide range of applications, bearings have evolved into various types. For example, bearings used in CT machines, primarily in X-ray tubes, consist of a core shaft, two rings, a sleeve, a C-ring, and several rollers. A flange is provided at one end of the core shaft. The two rings are respectively fitted around the core shaft near one end and the other, forming raceways with the core shaft. The rollers are mounted in the two raceways, and the sleeve and C-ring are fitted between the two rings of the core shaft. This results in tests for parameters such as clearance torque, which require applying a force to the bearing's outer ring and then observing the change in displacement. Because the outer ring of such bearings is typically composed of four separate components: two rings, a sleeve, and a C-ring, this can be challenging or lead to inaccurate test results. Therefore, a fixture is required to integrate the four components of the bearing's outer ring to facilitate testing. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides a CT machine bearing locking assembly that is easy to install and can assist in locking the bearing, facilitate detection, and ensure accurate detection results.
[0004] To achieve the above-mentioned purpose, the present invention provides a CT machine bearing locking assembly that is easy to install, including a first sleeve and a second sleeve. The first sleeve is sleeved on one end of the bearing to be tested close to its flange, and the first sleeve includes a first abutment portion. The first abutment portion is used to abut and cooperate with the axial end face of a ring of the bearing to be tested close to the flange. The second sleeve is sleeved on the other end of the bearing to be tested, and the second sleeve includes a second abutment portion. The second abutment portion is used to abut and cooperate with the axial end face of the other ring of the bearing to be tested, and the first sleeve and the second sleeve are threadedly engaged.
[0005] The advantages of adopting the above technical solution are: by setting a first sleeve and a second sleeve, the first sleeve is sleeved on one end of the bearing to be tested close to its flange, and the first abutting portion of the first sleeve abuts the axial end face of one ring of the first sleeve, and the second sleeve is sleeved on the other end of the bearing to be tested, and the second abutting portion of the second sleeve abuts the axial end face of the other ring of the bearing to be tested, and finally the first sleeve and the second sleeve are screwed together, and the first sleeve and the second sleeve are screwed together, so that the first abutting portion and the second abutting portion form a locking mechanism for the two rings, sleeve and C-ring constituting the outer ring, so that the two rings, sleeve and C-ring form a whole, which facilitates subsequent testing and ensures the accuracy of the test results.
[0006] The present invention can be further configured to include an end cover, which can be mounted on the end of the first sleeve, and the end cover is provided with a plurality of circumferentially distributed elastic members, the second sleeve includes a plurality of connecting holes, the connecting holes are circumferentially spaced apart, and the elastic members can form a snap fit with the second sleeve through the connecting holes.
[0007] Through further configuration, an end cover with an elastic member is provided, so that the end cover is sleeved on the end portion of the first sleeve, and the elastic member can form a snap fit with the second sleeve through the connecting hole. After the first sleeve and the second sleeve are locked, the first sleeve and the second sleeve are tightened by the elastic member. On the one hand, since the first sleeve and the second sleeve are threaded together, there must be a gap between the threads for smooth rotation. The tightening of the elastic member can keep the threads of the first sleeve and the second sleeve close to each other, avoiding inaccurate detection results. On the other hand, the elastic member can keep the threads close to each other, which can also avoid relative rotation during the detection process, thereby ensuring smooth detection.
[0008] The present invention can be further configured as follows: the second sleeve is screwed onto the outside of the first sleeve, the first sleeve includes a through groove, the through groove passes through both axial ends of the first sleeve and is used to connect the inside and outside of the first sleeve, and the width of the through groove is greater than the diameter of the ring.
[0009] By further setting, the second sleeve is screwed on the outside of the first sleeve, and the first sleeve corresponds to the end of the flange of the bearing to be tested and a through groove is provided on the first sleeve. The through groove is set to pass through the axial ends of the first sleeve and is used to connect the inside and outside of the first sleeve, and the width of the through groove is greater than the diameter of the ring, so that when the component of the present application is installed on the bearing to be tested, the first sleeve can pass through the flange of the bearing to be tested laterally, and then move axially until its first abutting portion abuts against the outer ring, and then the second sleeve is sleeved on the outside of the first sleeve, and the two are screwed together by rotation, which facilitates the installation of the first sleeve and the second sleeve.
[0010] The present invention can be further configured as follows: the first sleeve connector includes a limiting inner wall, the limiting inner wall extends to the sleeve of the bearing to be tested, and the limiting inner wall can abut and cooperate with the outer wall of the ring and the sleeve.
[0011] Through further settings, a limiting inner wall is provided on the first sleeve, so that the limiting inner wall is in abutment with the outer ring and the sleeve. On the one hand, the outer ring and the sleeve can be limited by the first sleeve to ensure the concentricity of the two. On the other hand, through the abutment with the outer ring and the sleeve, it can also provide limitation for itself, which is convenient for subsequent installation.
[0012] The present invention may be further configured as follows: the second abutting portion is arranged in an annular shape and is formed with a hole portion, and the diameter of the hole portion is larger than the diameter of the bearing to be measured.
[0013] By further configuring the hole in the second abutting portion with a diameter larger than the diameter of the bearing to be tested, mutual interference between the second sleeve and the core shaft of the bearing to be tested can be avoided, thereby avoiding affecting the test.
