Abstract

The invention can be used to balance grinding wheels on the go and allows you to expand operational capabilities by expanding the range of operating speeds. The device comprises a cylindrical body, in the center of which a finger is fixed. Four sleeves are mounted on the axis with the possibility of rotation. On each of the bushes a pair of radial partitions is fixed formed by them opposite chambers facing each other. The chambers are designed to be filled with balancing fluid. The fluid receiver is made in the form of concentric grooves, each connected to its chamber at the largest radius of the radial tube, made in conjunction with the drainage tube. In each chamber, sealed containers of elastic material are placed and fixed on radial channels. The liquid distributor is installed with a gap relative to the receiver opposite the concentric channels. When fluid is supplied to one of the chambers, the radial partitions turn and squeeze the fluid from the opposite chamber. 2 ill. SL C

Description

The invention relates to mechanical engineering and can be used for balancing grinding wheels and rotors on the go.

The aim of the invention is to expand the operational capabilities of the device by increasing the transmission coefficient of exposure between cameras.

Figure 1 presents a section of the device; FIG. 2 is a section AA in FIG. 1.

The balancing device comprises a cylindrical body 1, in the center of which a pin 2 is fixed. On the finger, sleeves 3, 4, 5, 6 are mounted. Each pair of sleeves has a pair of radially diametrically opposite partitions 7, 8, 9, 10, 11, 12 , 13, 14

dividing the housing into chambers 15 and 16, 17 and 18. 5a9k-yes sleeve with partition walls of equations & aegia relative to the axis of rotation. The chambers are designed to be filled with balancing fluid. The fluid receiver is made in the form of concentric grooves 19 on the end face of the cylindrical body, each connected to its chamber at the largest radius with a radial tube 20 and a drain tube 21. In each chamber, sealed radial tubes 22 are made of elastic material. The distributor 23 is installed with a gap relative to the fluid receiver opposite the concentric grooves.

The device operates as follows. .

Through the distributor 23, the balancing fluid is supplied into one or two concentric grooves 19 of the fluid receiver. From the concentric grooves, under the action of centrifugal forces, the balancing fluid enters the radial tubes 20. for example, adjacent chambers 15 and 17. In this case, part of the fluid exits through the drainage tubes 21. Under the influence of the fluid pressure, determined by the height of the liquid column from the concentric groove to the largest radius of the chambers, the liquid fills the sealed containers 22 and pushes the radial partitions 7 and 9, 12 and 14. The radial partitions 8 and 10, 11 and 13 attached to the same bushings converge, compressing the sealed containers 22 in their chambers 16, 18. The liquid displaced here rises through the radial tubes 20 and exits through the drainage tubes 21. The pressure in the chambers 16,18 is determined by the height of the liquid column from the largest radius of the chambers to the drainage channel, which is less than the height of the liquid column in the opposite chambers, so the balancing will continue until the respective radial baffles come close to touch. For rebalancing, the fluid is supplied to the opposite chambers and the whole process is repeated in the same order, with / now a greater pressure of the chambers 16,18 will push the liquid out of the chambers 15,17.

Thus, the rebalancing process can be carried out an unlimited number of times without stopping rotation at any operating frequency.

The use of a balancing device can also improve the accuracy and quality of processing on grinding machines and increase the durability of the machines themselves.
