Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and in particular to a combination structure of slider and bearing. Background Technology

[0002] Due to the inherent structural limitations of traditional sliders and grooves, the friction between the slider and the groove is relatively large, resulting in severe wear on the structure. Therefore, in applications that emphasize slider response speed and sensitivity, traditional slider structures are often unsuitable.

[0003] Traditional slider structures also have relatively large limitations on the degree of freedom. When subjected to force, the point of force application often cannot be synchronized with the direction of the force due to structural reasons, making it difficult to achieve the best performance of the material. Utility Model Content

[0004] In view of the above problems, the purpose of this application is to provide a slider and bearing combination structure, so that the slider no longer directly contacts the hinge seat structure, and several rows of longitudinally arranged cylindrical rollers are set between the two. This structure can effectively reduce the friction between the slider and the hinge seat structure.

[0005] To achieve some or all of the above objectives or other objectives, this application provides the following technical solution: a slider and bearing combination structure, including a slider, the slider being slidably connected to a hinge seat structure via two opposite sides, each of the two sides of the slider in contact with the hinge seat structure being provided with a groove, the groove being provided with at least one row of cylindrical rollers arranged longitudinally along the sliding direction, the slider being slidably connected to the hinge seat structure via the cylindrical rollers.

[0006] Furthermore, it also includes a retainer disposed within a groove, the retainer serving to isolate and retain the cylindrical roller.

[0007] Furthermore, the cage is a straight plate structure formed by stamping.

[0008] Furthermore, the cage is provided with three rows of twelve columns of pockets for accommodating cylindrical rollers.

[0009] Furthermore, the cage has a locking lug on its pocket, which is interference-fitted with the cylindrical roller.

[0010] Furthermore, a rectangular groove is provided on each of the two symmetrical sidewalls of the slide, and a retainer is provided in the rectangular groove.

[0011] Furthermore, it also includes a Phillips head countersunk screw; the cage has a through hole, the slider has a threaded hole, the threaded hole matches the through hole, and the Phillips head countersunk screw passes through the through hole and is screwed into the threaded hole to fix the cage in the rectangular groove.

[0012] Furthermore, the surfaces of the slider, groove, and cylindrical roller are coated with molybdenum disulfide.

[0013] Furthermore, the slider is provided with a shaft hole for cooperating with the rotating shaft, and a copper-based self-lubricating bushing or connecting bearing is provided between the shaft hole and the rotating shaft; when a copper-based self-lubricating bushing or connecting bearing is provided between the shaft hole and the rotating shaft, the shaft hole of the slider is configured as the outer ring of the connecting bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting longitudinally arranged cylindrical rollers between the slider and the hinge seat structure, the traditional sliding friction is transformed into rolling friction, which effectively reduces the friction force when the slider moves, improves the response speed and sensitivity, and at the same time greatly reduces the wear of the contact surface and extends the service life of the structure.

[0015] The use of a cage to isolate and hold the cylindrical rollers ensures the uniformity and stability of the roller arrangement, making the slider move more smoothly, reducing jamming and vibration, and helping to improve the accuracy of motion control. Attached Figure Description

[0017] To make the structure and function of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example 1 See appendix Figure 1-8 A slider and bearing combination structure includes a slider 1, which is slidably connected to a hinge seat structure 14 through two opposite sides. A groove 2 is provided on each of the two sides of the slider 1 that contact the hinge seat structure 14. At least one row of cylindrical rollers 3 arranged longitudinally along the sliding direction is provided in the groove 2. The slider 1 is slidably connected to the hinge seat structure 14 through the cylindrical rollers 3.

[0019] It also includes a retainer 4, which is disposed in the groove 2. The retainer 4 is used to isolate and retain the cylindrical rollers 3. The retainer 4 regularly isolates the cylindrical rollers to reduce the number of rollers and further reduce friction.

[0020] The retainer 4 is a straight plate structure formed by stamping.

[0021] The retainer 4 has three rows and twelve columns of pockets 5 for accommodating the cylindrical rollers 3.

[0022] The retainer 4 has a locking slot 6 on the pocket 5, which is interference-fitted with the cylindrical roller 3 to prevent it from falling off.

[0023] A rectangular groove 7 is formed on each of the two symmetrical sidewalls of the slide groove 2, and a retainer 4 is provided in the rectangular groove 7. The distance between the axis of the rectangular groove 7 and the bottom of the slide groove 2 is equal to 1 / 2 the diameter of the cylindrical roller 3.

[0024] It also includes a cross-slot countersunk screw 8; the retainer 4 is provided with a through hole, the slider 1 is provided with a threaded hole 9, the threaded hole 9 matches the through hole, and the cross-slot countersunk screw 8 passes through the through hole and is screwed into the threaded hole 9 to fix the retainer 4 in the rectangular groove 7.

[0025] During assembly, first insert the retainer 4 into the rectangular groove 7, drill a threaded hole 9 at a suitable position on the slider 1, screw in the cross-slot countersunk screw 8 to fix the retainer 4, and then press the cylindrical roller 3 in through the reserved locking amount to complete the assembly.

[0026] The surfaces of the slider 1, the groove 2, and the cylindrical roller 3 are coated with molybdenum disulfide. Since the slider and groove structure is difficult to seal, the lubrication method uses molybdenum disulfide coating, which makes the structure corrosion resistant, high temperature resistant, and lubricating.

[0027] The slider 1 is provided with a shaft hole 10 for cooperating with the rotating shaft 11, and a connecting bearing 13 is provided between the shaft hole 10 and the rotating shaft 11; when the shaft hole 10 and the rotating shaft 11 are connected by the bearing 13, the shaft hole 10 of the slider 1 is configured as the outer ring of the connecting bearing 13.

[0028] The inner diameter of the slider 1 and the rotating shaft 11 is made into the form of a connecting bearing sleeve. Replacing the bushing with a connecting bearing can further improve the degree of freedom of the structure.

[0029] Example 2 See appendix Figure 9-11 If high rigidity is required, a copper-based self-lubricating bushing 12 is provided between the shaft hole 10 and the rotating shaft 11.

[0030] Other technical solutions are the same as in Example 1.
