Balance and uniformity are major factors affecting safe use of the tire. In the existing tire balance and uniformity test process, a vertical balance and uniformity tester is generally adopted. During testing, the tire is clamped on the rotating main shaft, the tire needs to be filled with gas with certain pressure, and a certain amount of high-pressure gas needs to be filled into the upper rim shaft clamping cylinder until the testing is finished. If the cylinder needs to be introduced with two paths of gas, a multi-channel rotating mechanism needs to be configured.
In the existing gas path multi-channel rotating mechanism, as shown in fig. 1, a support bearing 4 is fixed by an upper bearing end cover 2 and a lower bearing end cover 10 which are fixed with a swing frame body 7 through hexagon socket head cap screws 3 in the radial direction respectively; in addition, the lock sleeve 8, the stopper washer 9 for nut, and the nut 101 are used to seal the bearing 4. A circular distribution sleeve 6 is arranged between the main shaft 1 and the supporting bearing 4, three sealing rings 5 are designed to realize gas separation, the outer two rings isolate compressed air from the outside, and the middle one ring separates two gases with different pressures. The rotary spindle 1 is correspondingly provided with through holes in the axial direction, so that the respective gas can reach the destination.
As described in the above structure, the conventional air path multi-channel rotating mechanism has the following problems and disadvantages:
1. the flow passage of compressed air is small, the tire inflation and deflation speed is slow, and the production period is influenced;
2. the main shaft rotates at a high speed to enable the sealing ring to generate heat through friction, the temperature cannot be diffused, the temperature of the rotating main shaft and the main shaft supporting bearing and the temperature of the rotating distribution sleeve are increased, bearing lubricating grease is easy to melt and run off, the lubricating condition of the bearing is reduced, and therefore the service life of the bearing is shortened;
3. the bearing load of the main shaft supporting shaft is increased, the fixing condition of the main shaft is changed, and the test data is unstable.
Disclosure of Invention
Gas circuit multichannel rotary mechanism, can solve above-mentioned problem and not enough and be provided with the rotatory main shaft that possesses central round hole and outer lane porous channel, divide the supporting compressed air to provide experimental tire and last rim axle die clamping cylinder through the rotation to solved and set up the rotation between two sets of supporting bearing and divide supporting defect.
The gas circuit multi-channel rotating mechanism mainly comprises a rotating main shaft, an inner spacer sleeve, a rotating distribution sleeve, a shell, a sealing ring and the like.
The shell is connected with the upper bearing end cover and the lower bearing end cover through fixing screws respectively.
The rotating main shaft is arranged at the center of the shell and fixedly connected with the multi-wedge belt wheel above the rotating main shaft through screws, the outer peripheral side of the rotating main shaft is sleeved with an inner spacer sleeve, and the outer peripheral side of the inner spacer sleeve is sleeved with a rotating distribution sleeve.
The rotating main shaft is of a hollow structure, and an air cylinder air supply port and a tire air supply port are formed in the rotating main shaft and are communicated with vent holes formed in the inner partition sleeve and the rotating distribution sleeve. The required compressed air can pass through the interior of the main shaft.
And a plurality of O-shaped sealing rings are respectively arranged on the periphery sides of the air supply port of the air cylinder of the rotating main shaft, the air supply port of the tire, the air vent holes of the inner partition sleeve and the rotating distribution sleeve so as to separate the air vent holes from each other.
The multi-wedge belt wheel is driven by the multi-wedge belt of the motor, and the multi-wedge belt wheel and the rotating main shaft are fixed together in a screwing or riveting mode, so that the combined body rotates at a high speed in the multi-channel rotating mechanism.
The rotating main shaft is provided with a central circular hole and an outer ring multi-hole channel.
Compressed air is supplied to the tire and upper rim shaft clamping air cylinder or other air cylinders through the rotating distribution sleeve and passes through the rotating main shaft.
The shell of the gas circuit multi-channel rotating mechanism is fixedly connected with the swing frame body through the middle connecting piece and is not directly connected with the rotating main shaft.
The gas path multi-channel rotating mechanism has the following obvious advantages and beneficial effects:
1. the gas required by the tire test can be rapidly and stably provided;
2. the influence of the friction of the sealing ring on the main shaft of the rotating main shaft due to heat rise is effectively avoided, and the accuracy and the stability of the test result of the tire are ensured.
