Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a double-sided oiling device for bearings. Background Technology

[0002] When a bearing operates at high speed, internal friction not only increases energy consumption but also damages the bearing and reduces its normal service life. Therefore, after the bearing is assembled, lubricating oil needs to be injected into it to reduce wear.

[0003] Most existing bearing lubrication equipment consists of a lubrication gun, an oil tank, and an oil pump. The oil pump supplies lubricating oil from the oil tank to the lubrication gun, and then a worker manually holds the lubrication gun to lubricate various points on the side of the bearing. During the lubrication process, the worker must move the lubrication gun along a circular trajectory on the side of the bearing and perform double-sided lubrication to ensure comprehensive lubrication of both sides of the bearing. This results in high labor intensity for the worker and also makes the bearing lubrication process time-consuming and inefficient. Therefore, a double-sided lubrication device for bearings is proposed. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1-3 The illustrated double-sided lubrication device for bearings includes a U-shaped seat 100. A vertical clamping mechanism is provided inside the U-shaped seat 100, allowing the bearing to be vertically clamped and positioned within the U-shaped seat 100. Lubrication guns 107 are symmetrically arranged on both sides of the U-shaped seat 100, with their outlets facing the bearing sidewalls clamped by the vertical clamping mechanism for lubrication. The lubrication guns 107 are connected to an external oil tank via hoses and an oil pump to ensure lubrication supply. By vertically placing the bearing within the U-shaped seat 100 and clamping it with the vertical clamping mechanism, and then applying lubricating oil via the lubrication guns 107 on both sides of the U-shaped seat 100, simultaneous lubrication of both bearing sidewalls is achieved, eliminating the tedious process of lubricating each bearing individually and improving the efficiency of bearing lubrication.

[0020] The vertical clamping mechanism includes a stationary clamp 101, a movable clamp 102, and two sets of cylindrical rollers 103. The stationary clamp 101 and the movable clamp 102 are spaced apart from bottom to top inside the U-shaped base 100. The stationary clamp 101 is fixed to the bottom of the inner side of the U-shaped base 100. The top of the U-shaped base 100 is provided with a driving component for driving the movable clamp 102 to rise and fall. Each set of cylindrical rollers 103 consists of two rollers and is rotatably connected to the opposite side of the stationary clamp 101 and the movable clamp 102. A 115 is fixedly inserted into the bottom of the shaped seat 100. The output shaft of the 115 passes through the side wall of the stationary clamp 101 and is connected to one end of the cylindrical roller 103 at the corresponding position. By using two cylindrical rollers 103 spaced apart on opposite sides of the stationary clamp 101 and the movable clamp 102, four-point clamping of the bearing on both the upper and lower sides can be achieved. This not only ensures the stability of the bearing positioning but also allows the bearing to rotate between the stationary clamp 101 and the movable clamp 102, thereby changing the injection... The system is designed to accommodate various bearing sizes, offering high adaptability. It drives the corresponding cylindrical roller 103 to rotate via 115. The frictional resistance between the cylindrical roller 103 and the bearing's outer wall causes the bearing to rotate, allowing the grease gun 107 to inject grease at different points on the bearing's sidewall ring track, ensuring more comprehensive grease coverage. The driving mechanism includes a top cover 104 fixedly connected to the top of the U-shaped seat 100 and a hydraulic telescopic rod 105 fixedly installed in the middle of the top cover 104. The telescopic end of the hydraulic telescopic rod 105 is fixed to the middle of the movable clamping seat 102. Connecting the hydraulic telescopic rod 105 to an external cylinder and valve enables its extension and retraction, thereby driving the movable clamping seat 102 to move up and down, allowing it to accommodate and position bearings of various sizes.

[0021] Furthermore, the U-shaped seat 100 is provided with height adjustment mechanisms on both sides. The height adjustment mechanisms include straight through holes 108 opened on both side walls of the U-shaped seat 100. A slider 106 that moves vertically along the straight through hole 108 is movably disposed in the straight through hole 108. An oil gun 107 is fixedly inserted into the middle of the slider 106. A locking element is provided between the slider 106 and the straight through hole 108. The locking element includes a threaded sleeve 110 and a threaded rod 109. The bottom end of the slider 106 is fixedly connected to the threaded sleeve 110. The bottom end of the threaded sleeve 110 is threadedly inserted into the threaded rod 109. The bottom end of the threaded rod 109 rotates with the bottom of the straight through hole 108. The height of the grease gun 107 needs to be adjusted according to the different bearing sizes. The adjustment process only requires rotating the threaded rod 109 clockwise or counterclockwise. Due to the limiting and guiding effect of the linear through hole 108, the slider 106 rotates while the threaded rod 109 rotates. The threaded compression between the threaded rod and the inner wall of the threaded sleeve 110 drives the threaded sleeve 110 to move up and down along the axial direction of the threaded rod 109, thereby adjusting the height of the grease gun 107 so that the grease gun 107 can be kept flush with the top of the bearing side wall, thus keeping the grease gun 107's grease injection position accurate. In addition, a rotating shaft 112 is rotatably connected to the cavity at the bottom of the U-shaped seat 100. The two ends of the rotating shaft 112 are fixedly connected to the second bevel gears 113. The top of one side of the second bevel gears 113 is meshed with the first bevel gear 111. The bottom of the threaded rod 109 extends into the cavity at the bottom of the U-shaped seat 100 and is fixed to the first bevel gear 111. The servo motor 114 drives the rotating shaft 112 to rotate clockwise or counterclockwise, thereby driving the two second bevel gears 113 to rotate synchronously in the same direction. With the meshing and reversing transmission of the first bevel gear 111, the two threaded rods 109 can be driven to rotate synchronously in the same direction, thereby satisfying the synchronous adjustment of the height of the two oil guns 107 and improving the convenience and efficiency of the adjustment operation.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
