Description

Technical Field

[0001] The invention belongs to the technical field of float glass processing equipment, and in particular relates to a device for replacing roller bearings of an ultra-thin float glass annealing furnace. Background Art

[0002] In float glass production, the molten glass is formed in a tin bath, and then enters the annealing furnace through a transition roller table. After annealing, it is cut into glass products. Due to the continuity and uninterrupted nature of production, some production equipment has a great impact on product quality when it fails and needs to be repaired and replaced. The transition roller table and annealing furnace are key equipment in glass production. The glass plate passes through the transition roller table and annealing furnace through dozens or hundreds of rollers. The bearings at both ends of each roller are loss devices and need to be replaced from time to time. During the replacement process, the rotation of the roller needs to be stopped, placed on the support table, and separated from the glass plate. When ordinary float glass production lines perform this operation, the impact may not be significant, but in ultra-thin glass production lines, since the glass thickness is less than 1.1mm, and the thinnest can even reach 0.1mm, the above operation is likely to cause the risk of glass breaking.

[0005] The auxiliary rotating device comprises a support rod horizontally penetrating the mounting through hole on the bracket fork; an auxiliary bearing is arranged at the front end of the support rod; the inner ring of the auxiliary bearing is interference fit with the front end of the support rod; the outer ring of the auxiliary bearing is in line contact with the circumferential surface of the roller.

[0016] The present invention will be described below in conjunction with the accompanying drawings.

[0017] like Figure 1-Figure 3 A device for replacing roller bearings of an ultra-thin float glass annealing furnace is shown, comprising a base 1, a bracket 2 is vertically arranged on the upper part of the base 1; the bracket 2 is a Y-shaped bracket, and mounting through holes are symmetrically arranged on the two forks of the Y-shaped bracket, and symmetrically arranged auxiliary rotating devices are arranged through the mounting through holes, and a roller 3 is placed between the two forks of the Y-shaped bracket and in contact with the auxiliary rotating device; a driving device is connected to the end of the auxiliary rotating device; the driving device is used to drive the auxiliary rotating device and then drive the roller 3 to rotate, thereby completing the requirement of replacing the bearing.

[0018] The auxiliary rotating device includes a support rod 4 horizontally passing through the mounting through hole on the fork of the bracket 1; an auxiliary bearing 5 is provided at the front end of the support rod 4; the inner ring of the auxiliary bearing 5 is interference fit with the front end of the support rod 4; the outer ring of the auxiliary bearing 4 is in line contact with the circumferential surface of the roller 3; the outer ring surface of the auxiliary bearing 4 is provided with a rubber layer, and the rubber layer is provided to increase the friction force when the auxiliary bearing and the roller are in contact; the driving device includes a driven gear 6 arranged at the end of each support rod 4; a driving gear 7 connected to it by a gear is provided between the driven gears 6; a transmission gear rod 8 is connected to the driving gear 7; a coupling 9 is connected to the end of the transmission gear rod 8, and a speed sensor 10 is also provided on the transmission gear rod 8, and the speed sensor 10 is used to monitor the rotation speed of the driving gear 7 so as to The running speed of the motor 12 is adjusted, and then the gear ratio is adjusted to meet the use requirements; the coupling 9 is connected to the transmission belt 11 at its end through a transmission shaft; the end of the rotating belt 11 is connected to the motor 12 through an output shaft; the motor 12 is a variable frequency motor, and the setting of the variable frequency motor is used to adjust the rotation speed of the motor 12 and then adjust the transmission ratio between each gear to meet the use requirements; the transmission ratio of the driving gear 7 and the driven gear 6 is 1:1.5; the transmission ratio of the driving gear 7 and the transmission belt 11 is 1:1; the coupling 9 is a pin structure, and a threaded pin hole is provided on the coupling 9; a threaded pin 13 is provided in the pin hole; the purpose of the threaded pin 13 is to control the meshing of the coupling 9, and the coupling 9 can be manually meshed and disengaged when the motor 12 is not running as needed.

[0019] When the present invention is in use, the device is placed below the end of the roller 3 whose bearing needs to be replaced. When the bearing on the non-transmission roller 3 needs to be replaced, the threaded pin 13 on the coupling 9 is removed to separate the coupling 9. At this time, the motor 12 is not started, and the roller 3 is supported by the Y-shaped bracket 1 so that the two auxiliary bearings 5 ​​are in contact with the roller 3 to keep the normal rotation of the roller 3, and the bearing on the roller 3 can be disassembled; when the bearing on the roller 3 on the transmission side needs to be replaced, the threaded pin 13 on the coupling 9 is screwed in to make the coupling 9 mesh, and the motor 12 is started at this time. Since the transmission ratio of the driving gear 7 and the driven gear 6 is 1:1.5, by setting the speed of the motor 3 to 2 / 3 of the actual roller 3 speed, the speed finally transmitted to the roller 3 by the auxiliary bearing 5 is the same as the speed of other running rollers, and the bearing on the roller 3 can be disassembled at this time; after the replacement is completed, the motor 12 is turned off, the coupling 9 is separated, and the bracket 1 is withdrawn.
