SU1255801A2 - Arrangement for plastic circulating lubrication - Google Patents

Description

The invention relates to mechanical engineering, can be used mainly in bearing units (sliding) of rotating shafts and axles, 3 gear, chain transmissions and other devices with plastic (thick, grease) lubricant and is an improvement of the device according to the author. St. No. 1008564.

The purpose of the invention is to increase the reliability and efficiency of lubrication of the lubricated unit due to the forced return of the flexible diaphragm to the position for the injection of lubricant.

FIG. 1 shows a device of a plastic circulation lubricant, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device includes a housing 1, an end cap 2, a rotating shaft 3, a lubricated rolling support unit 4, a flexible (rubber) diaphragm 5, an activator roller b pod rollers 7. The rollers b and 7 are mounted on axles 8 which are fixed radially on the sticking shaft 3. The flexible diaphragm 5, made in the form of a thin disk, is fixed along the outer edge on the end face of the lid 2. The roller activator 6 is installed in the circular cavity 9 so that it is constantly in the same place but the circle presses the flexible diaphragm 5 from the end of the cover 2. Gland rollers 7 mouth ovleny a circular cavity 9 so that running out permanently flexible diaphragm 5 to the end caps 2. A-A

A device for circulating plastic lubrication of a unit (for example, a rolling bearing) operates as follows.

With the rotation of the shaft 3 on the bearing 4

the rollers 6 and 7 also rotate with it, while the rollers 7 press the flexible diaphragm 5 to the flap 2, and the activator rollers 6 press the edge of the flexible diaphragm 5, providing it with a circular traveling deformation wave, which is successively

The circular cavity 9 squeezes the grease into the lubricated unit (rolling bearing 4). In this way, active circulation and effective renewal of the grease in the lubricated unit are carried out. Per one rotation of rotation of the shaft 3, one cycle of circular lubrication of the unit is performed. The constant clamping of the flexible diaphragm 5 to the end cover 2 with the help of gland rollers 7 ensures the same stroke of the flexible diaphragm and stable

the amount of grease in lubricated site. The stability of lubricant performance ensures reliable and durable operation of the lubricated unit, reducing friction in it and energy consumption, and also allows for more efficient use of the lubricant.

In order to increase the amount of circulating grease in a lubricant unit per unit of time, several rotating rollers 6 and 7 can be installed on the rotating shaft 3; in proportion to this, the amount of grease to be driven through the lubricated unit will increase.
