Description

Technical Field

[0001] The utility model relates to the technical field of ball bearing applications, in particular to a clamping tool for a high-reliability line-contact ball bearing. Background Art

[0002] A ball bearing is a rolling bearing consisting of an inner steel ring, an outer steel ring, and a ball sandwiched in between. It can withstand large loads and reduce rotational friction. Ball bearings are widely used, including but not limited to industrial machinery, automobiles, household appliances, etc. For example, ball bearings are an important component in textile machinery, printing machinery, agricultural machinery and other equipment. There are also many types of ball bearings, such as deep groove ball bearings and angular contact ball bearings. Each type has its specific application occasions and performance characteristics.

[0003] During the use of existing bearings, the steel balls inside are generally arranged tangentially to the raceways inside the inner and outer steel rings. As a result, the load force they are subjected to during use acts on the tangent points, which makes the load intensity at the point contact position between the steel balls and the raceways too high, causing wear during long-term use and reducing the service life of the entire bearing. Therefore, the utility model proposes a clamping tool for high-reliability line contact ball bearings. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a clamping fixture for a high-reliability linear contact ball bearing. By setting the contact position between the outer wall of the steel ball and the inner and outer steel rings to linear contact, the entire bearing can increase the load-bearing capacity of the entire bearing during use by utilizing the high load-bearing effect increased by the linear contact of the steel ball, thereby increasing its service life. In addition, a matching assembly clamping component is provided to enable the bearing to be clamped and fixed multiple times quickly during the assembly process, thereby improving the assembly stability and efficiency of multiple bearings.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a clamping fixture for a high-reliability line contact ball bearing, including an outer steel ring and an inner steel ring, and a plurality of steel balls evenly distributed between the outer steel ring and the inner steel ring.

[0009] The above technical solution facilitates the stable engagement and fixation of the sealing rings on both sides, thereby preventing the intrusion of external dust during use and improving the service life of the entire bearing.

[0010] The utility model is further configured as follows: the two retaining frames are fixed by relative riveting.

[0011] Through the above technical solution, the retaining frame can remain stable during long-term use, prevent the falling off that occurs in traditional connection methods, and stably maintain the phase distance between the internal steel balls.

[0012] The utility model is further configured as follows: the high-reliability line contact ball bearing is clamped and fixed by the following clamping tool, the clamping tool includes a conveyor belt, the side walls of the conveyor belt are symmetrically installed with side frames, the side walls of the two side frames are fixedly connected with an assembly clamping component, the assembly clamping component includes a clamping cylinder installed at the bottom center of the side frame, the end face of the driving rod of the clamping cylinder is bolted to a connecting plate, the end face of the connecting plate is bolted to a fixed pull rod, the end face of the fixed pull rod is bolted to a connecting frame, the bottom of the connecting frame is bolted to a splint, and the side walls of the splint are evenly provided with multiple arc grooves.

[0013] Through the above technical solution, the clamping cylinder is started, and its driving rod drives the movement of the connecting plate on the end face, which in turn drives the clamping plate on the connecting frame connected to its end face to slide through the fixed pull rod connected by bolts, and slides stably on the side frame. At the same time, under the action of the two stabilizing sliding rods on the side, the clamping plate can quickly clamp and fix the moving bearing on the conveyor belt through the internal arc groove, thereby facilitating the rapid assembly of the internal parts of the bearing.

[0014] The utility model is further configured as follows: the end surface of the connecting frame is symmetrically bolted with a stabilizing slide bar, the top of the side frame is bolted with a stabilizing frame near the side wall, and the two stabilizing slide bars and the fixed pull rod all pass through the stabilizing frame and are slidably connected thereto.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0028] like Figure 1-Figure 4 As shown, a clamping fixture for a high-reliability line contact ball bearing comprises an outer steel ring 100 and an inner steel ring 200, and a plurality of steel balls 300 uniformly distributed between the outer steel ring 100 and the inner steel ring 200. The inner wall of the outer steel ring 100 is provided with an arc-shaped outer raceway 101, and an external stress fillet 102 is provided at the transition between the outer raceway 101 and the outer steel ring 100. The outer wall of the inner steel ring 200 is provided with an arc-shaped inner raceway 201, and an internal stress fillet 202 is provided at the transition between the inner raceway 201 and the inner steel ring 200. The outer walls of the plurality of steel balls 300 are smoothly fitted with the arc-shaped walls of the outer raceway 101 and the inner raceway 201, so that when the plurality of steel balls 300 roll inside the outer raceway 101 and the inner raceway 201, the external stress fillet 102 and the internal stress fillet 202 can be used to In order to reduce the wear between each other, the outer walls of the multiple steel balls 300 are symmetrically fitted with a retaining frame 400, and the two retaining frames 400 are relatively riveted and fixed, so that the retaining frame 400 can remain stable during long-term use, and prevent the traditional connection method from falling off, and stably maintain the phase distance of the internal steel balls 300. The side walls of the outer steel ring 100 are symmetrically connected with sealing rings 500, and the side walls of the outer steel ring 100 are symmetrically provided with sealing grooves 103 near the inner wall. The two sealing rings 500 are respectively engaged with the two sealing grooves 103, and the inner wall is fitted with the outer wall of the inner steel ring 200, so that the sealing rings 500 on both sides are stably engaged and fixed, thereby preventing the entry of external dust during use and improving the service life of the entire bearing.

[0029] like Figure 5As shown, the clamping tooling includes a conveyor belt 600, and the side walls of the conveyor belt 600 are symmetrically installed with side frames 700. The side walls of the two side frames 700 are fixedly connected with an assembly clamping assembly 800. The assembly clamping assembly 800 includes a clamping cylinder 801 installed at the bottom center of the side frame 700, and the end face of the driving rod of the clamping cylinder 801 is bolted to a connecting plate 802, and the end face of the connecting plate 802 is bolted to a fixed pull rod 803, and the end face of the fixed pull rod 803 is bolted to a connecting frame 804. The end face position of the connecting frame 804 is symmetrically bolted with a stabilizing slide bar 805, and the top of the side frame 700 is bolted to a stabilizing frame 701 near the side wall. The two stabilizing slide bars 805 and the fixed pull rod 803 all penetrate the stabilizing frame 701 and are slidably connected thereto, so that when the splint 806 is driven, it can slide inside the stabilizing frame 701 through the stabilizing slide bar 805 on the side, thereby making the splint 80 6 can stably support and fix the bearing that needs to be assembled. The bottom bolts of the connecting frame 804 are connected with a clamping plate 806. The bottom of the clamping plate 806 is slidably connected to the top of the side frame 700 through a guide rail, so that when the clamping plate 806 is driven, it can slide stably on the side frame 700, thereby improving the clamping stability of the bearing. The side wall of the clamping plate 806 is evenly opened with multiple arc grooves 807. When the clamping cylinder 801 is started, its driving rod drives the movement of the connecting plate 802 on the end face, and then drives the clamping plate 806 on the connecting frame 804 connected to its end face to slide through the fixed pull rod 803 connected by the bolts, and slides stably on the side frame 700. At the same time, under the action of the two stabilizing slide bars 805 on the side, the clamping plate 806 can quickly clamp and fix the moving bearing on the conveyor belt 600 through the internal arc groove 807, thereby facilitating the rapid assembly of the internal parts of the bearing.

[0030] When the present invention is in use, the clamping cylinder 801 is first started, and its driving rod drives the movement of the connecting plate 802 on the end face, and then the fixed pull rod 803 connected by bolts drives the clamping plate 806 on the connecting frame 804 connected to its end face to slide, and slide stably on the side frame 700. At the same time, under the action of the two stabilizing slide bars 805 on the side, the clamping plate 806 can quickly clamp and fix the moving bearing on the conveyor belt 600 through the internal arc groove 807, thereby facilitating the rapid assembly of the internal parts of the bearing. The outer walls of the multiple steel balls 300 inside the bearing are smoothly fitted with the inner arc walls of the outer raceway 101 and the inner raceway 201 set inside the outer steel ring 100 and the inner steel ring 200, forming linear contact, so that the steel balls 300 can increase the load force during use, thereby increasing the service life of the entire bearing.
