Description

The invention relates to mechanical engineering and can be used to apply a solid lubricant to the working surfaces of the teeth of an open heavy loaded pinwheel sprockets and gears.

The aim of the invention is to increase the durability of the device and the quality of the cake.

Fig. 1 shows a device for applying a solid lubricant to a pinwheel tooth, plan; figure 2 - section aa in figure 1: fig.Z - view B in figure 2; figure 4 - node 1 in figure 2.

The device contains a gear wheel I, on the teeth x 2 of which are placed the elements 3 of solid lubricant and the means 4 of pressing the wheel 1 to the lubricated surfaces 5. The elements 3 of solid lubricant are placed on the tooth 2 with the ability to move in the plane of rotation of the wheel 1; elements 3 solid lubricant in this plane in the form of an eccentric bushing 7 with eccentricity and a groove 8 in the bracket 9 fastening the device to the body.

Continuous contacting of the teeth 2 with the teeth of the star gear 10, as a result of which the working surfaces of the teeth are lubricated, is achieved by rotating the eccentric bushing 7 with a gear auxiliary transmission. The gear 11 of the gear auxiliary transmission is attached to the end of the sprocket sprocket 10, and the wheel 12 to the eccentric bushing 7. The number of teeth 2 and the number of gear teeth 11 and the gear 12 gear of the auxiliary gear are appointed according to the need to lubricate each tooth of the sprocket sprocket 10 before contacting it.

; To turn the eccentric bushing 7 to a small angle clockwise or counterclockwise, the eccentric bushing 7 is pressed 5 into the eccentric 13, which is held in a certain position by the springs 14.

A solid lubricant 3 is attached to each tooth 2 of the wheel 1, which is pressed against the working surfaces of the teeth of the sprocket 10. The distance between the solid lubricant 3 (plates of solid lubricant) is adjusted by screws 15.

The height of the teeth 2 is not constant, it varies according to

h + e (l-cosq), where h is the height of the tooth in the position

shown in figure 1; (p is the angle of rotation of the eccentric sleeve 7; e is the eccentricity of the sleeve 7.

The maximum height of the protrusion is 25 on h + 2e.

Consequently, the application of a solid lubricant (solid lubricant element) to the working surfaces of the teeth of the sprocket 10 is carried out due to the radial and circular movement of the teeth 2 in the plane of rotation of the wheel J.

The device works as follows.

The tooth 2 of the gears 1 enters the cavities between the teeth of the pinwheel or the gears, the solid lubricant elements 3 self-assembled with respect to the lubricated surface 5 by means of the pressure wheel 4 4. The solid lubricant elements 3 can move in the plane of rotation of the wheel 1 due to the presence of a drive 6 in the form of an eccentric sleeve 7 and a groove 8 of the bracket 9.
