Description

Technical Field

[0001] This utility model relates to the field of crossed cylindrical roller bearing technology, and more specifically to an adjustable crossed cylindrical roller bearing synchronous rotation mechanism. Background Technology

[0002] Crossed cylindrical roller bearings are high-precision, multi-directional load-bearing rolling bearings. They consist of two rows of cylindrical rollers arranged perpendicularly at 90°, separated by nylon spacers to prevent mutual friction and reduce rotational torque. Crossed cylindrical roller bearings are widely used in industrial robots, precision grinding machine tools, heavy machinery, and semiconductor manufacturing.

[0003] Existing crossed cylindrical roller bearings are equipped with a synchronous rotation mechanism. The synchronous rotation mechanism of crossed cylindrical roller bearings refers to an integrated system that achieves synchronous transmission of multi-directional loads and high-precision rotational motion through the special structural design of the bearing. However, the existing synchronous rotation mechanism of crossed cylindrical roller bearings cannot be adjusted. Therefore, an adjustable synchronous rotation mechanism for crossed cylindrical roller bearings is proposed. By setting a synchronous rotation pulley at the bottom of the crossed cylindrical roller bearing, synchronous rotation can be achieved. The synchronous rotation pulley has teeth evenly spaced on its outer side to facilitate its rotation and achieve the purpose of adjustment. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an adjustable cross cylindrical roller bearing synchronous rotation mechanism. By setting a synchronous pulley at the bottom of the cross cylindrical roller bearing, synchronous rotation is achieved. The synchronous pulley has teeth evenly spaced on its outer side to facilitate rotation and achieve the purpose of adjustment.

[0005] The technical solution adopted by this utility model to solve its technical problem is an adjustable cross cylindrical roller bearing synchronous rotation mechanism, including a rotating synchronous pulley, a bearing retaining ring, a cross cylindrical roller bearing and a bearing turntable. The bearing turntable is disposed on the top of the cross cylindrical roller bearing, and the bearing retaining ring and the rotating synchronous pulley are disposed sequentially on the bottom of the cross cylindrical roller bearing.

[0006] The outer side of the rotary synchronous pulley is provided with reinforcement components at equal intervals. The reinforcement components include internal threaded sleeves welded at equal intervals to the outer side of the rotary synchronous pulley. A screw rod is sleeved through the internal threaded sleeve, and a cross block is welded to one end of the screw rod.

[0007] By adopting the above technical solution, the rotary synchronous pulley, bearing retaining ring, crossed cylindrical roller bearing and bearing turntable form a crossed cylindrical roller bearing synchronous rotary mechanism. Tightening the screw can reinforce the rotary synchronous pulley through the cross block.

[0008] Specifically, a rubber sealing sleeve is fitted onto the end of the internal threaded sleeve away from the rotating synchronous pulley, and the screw passes through the rubber sealing sleeve.

[0009] Specifically, the outer side of the rotary synchronous pulley is provided with through slots at equal intervals, the inner threaded sleeve is provided on the outer side of the rotary synchronous pulley between the through slots, and the rotary synchronous pulley is provided with gear teeth at equal intervals on the outer side of the bottom of the through slot.

[0010] Specifically, the top of the rotary synchronous pulley is provided with a third mounting groove, and the bearing retaining ring is fixed in the third mounting groove by bolts.

[0011] Specifically, the bearing retaining ring has a second mounting groove at its top, the crossed cylindrical roller bearing is fixed to the inside of the second mounting groove by bolts, the crossed cylindrical roller bearing has a first mounting groove at its top, and the bearing turntable is fixed to the inside of the first mounting groove by bolts.

[0012] The beneficial effects of this utility model are:

[0013] The adjustable cross cylindrical roller bearing synchronous rotation mechanism of this utility model has through grooves equidistantly opened on the outer side of the synchronous pulley, which can reduce its weight without affecting the structural stability of the synchronous pulley. The synchronous pulley has teeth equidistantly arranged on the outer side of the bottom of the through groove, which can be easily driven to rotate by belts, gears, etc., to achieve the purpose of adjustment.

[0014] The adjustable cross cylindrical roller bearing synchronous rotation mechanism of this utility model, when no adjustment is required, allows personnel to use tools to rotate the screw. The rotation of the screw moves through the internal threaded sleeve, causing the cross block at one end of the screw to press against the outside of the equipment that is sleeved on the inside of the rotating synchronous pulley, thereby reinforcing the rotating synchronous pulley.

[0021] Synchronous rotation is achieved by installing a rotary timing pulley at the bottom of the crossed cylindrical roller bearing. The outer side of the rotary timing pulley has evenly spaced teeth to facilitate rotation and allow for adjustment.

[0022] The outer side of the rotary synchronous pulley 1 is provided with a reinforcing component 5 at equal intervals. The reinforcing component 5 includes an internal threaded sleeve 501 that is welded at equal intervals to the outer side of the rotary synchronous pulley 1. A screw 503 is sleeved through the internal threaded sleeve 501. A cross block 504 is welded to one end of the screw 503.

[0023] In use, the rotary synchronous pulley 1, bearing retaining ring 2, crossed cylindrical roller bearing 3 and bearing turntable 4 form a crossed cylindrical roller bearing synchronous rotary mechanism. Tightening screw 503 can reinforce the rotary synchronous pulley 1 through cross block 504.

[0024] For example, such as Figure 3 As shown, the present invention also includes a rubber sealing sleeve 502 fitted onto the end of the internal threaded sleeve 501 away from the rotating synchronous pulley 1, and the screw 503 passing through the rubber sealing sleeve 502.

[0025] In use, the rubber sealing sleeve 502 is used to seal between the internal threaded sleeve 501 and the screw 503.

[0026] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a through groove 6 equidistantly opened on the outer side of the rotary synchronous pulley 1, an internal threaded sleeve 501 disposed on the outer side of the rotary synchronous pulley 1 located between the through grooves 6, and teeth 7 equidistantly disposed on the outer side of the rotary synchronous pulley 1 located at the bottom of the through groove 6.

[0027] When in use, the opening of the through groove 6 can reduce the weight of the rotary synchronous pulley 1, and the setting of the gear teeth 7 makes it convenient for external equipment to drive the rotary synchronous pulley 1 to rotate.

[0028] For example, such as Figure 2 As shown, the present invention also includes a third mounting groove 10 provided on the top of the rotary synchronous pulley 1, and the bearing retaining ring 2 is fixed in the third mounting groove 10 by bolts.

[0029] In use, the rotary synchronous pulley 1 is fixed to the bottom of the crossed cylindrical roller bearing 3 by the bearing retaining ring 2, so as to achieve the purpose of synchronous rotation of the crossed cylindrical roller bearing.

[0030] For example, such as Figure 2 As shown, the present invention also includes a second mounting groove 9 provided on the top of the bearing retaining ring 2, the cross cylindrical roller bearing 3 being fixed inside the second mounting groove 9 by bolts, a first mounting groove 8 provided on the top of the cross cylindrical roller bearing 3, and the bearing turntable 4 being fixed inside the first mounting groove 8 by bolts.

[0031] During use, the bearing turntable 4 is fixed to the top of the bearing retaining ring 2 and can rotate.

[0032] In use, the bearing turntable 4 is fixed to the first mounting groove 8 on the top of the crossed cylindrical roller bearing 3 by bolts, the crossed cylindrical roller bearing 3 is fixed to the second mounting groove 9 on the top of the bearing retaining ring 2 by bolts, and the bearing retaining ring 2 is fixed to the third mounting groove 10 on the top of the rotary synchronous pulley 1 by bolts, so that the rotary synchronous pulley 1 is connected to the bottom of the crossed cylindrical roller bearing 3, thereby achieving the purpose of synchronous rotation of the crossed cylindrical roller bearing;

[0033] The outer side of the rotary synchronous pulley 1 is provided with through grooves 6 at equal intervals, which can reduce its weight without affecting the structural stability of the rotary synchronous pulley 1. The rotary synchronous pulley 1 is provided with gear teeth 7 at equal intervals on the outer side of the bottom of the through groove 6, which can be easily driven to rotate by belts, gears, etc., to achieve the purpose of adjustment.

[0034] When no adjustment is needed, personnel can use tools to rotate the screw 503. The rotation of the screw 503 moves the internal threaded sleeve 501, causing the cross block 504 at one end of the screw 503 to press against the outside of the equipment that is sleeved on the inside of the rotary synchronous pulley 1, thereby reinforcing the rotary synchronous pulley 1.
