Description

The invention relates to mechanical engineering and can be used to lubricate open gears lubricated with greases.

A lubricating device in the form of a blade is known by which a grease is applied to the working surfaces of gears.

The disadvantage of this lubricating device is its low productivity, high complexity and fragility of the applied lubricant.

As a prototype, a gear lubricating device is used, which is a blade, by which a plastic lubricant is applied manually on the working surfaces of the gears,

The disadvantage of this lubricating device is that it can provide lubrication only during interruptions in the operation of the gear transmission, which is ineffective. During transmission operation, the lubricant is quickly displaced from the working surfaces of the gears, which stimulates the process of their wear.

The purpose of the invention is to increase lubrication efficiency.

To achieve this goal, the gear lubrication device includes a device for applying lubricant to the working surfaces of the gears, and according to the invention, the device for applying lubricant is made in the form of a pair of elastic plates fixed motionless on both sides of each gear wheel inclined to its ends teeth and in its diametrical plane - the length of the plates is greater than the height of the gear teeth, and

slots are made on the edges of the plates facing the tooth m.

The invention is illustrated in the drawing, which shows: a gear wheel (fragment) and a lubricating device - side view.

The gear lubricating device is arranged as follows. Each of the gears 1 with teeth 2, having end 3 and working 4 surfaces, is equipped with a pair of elastic lubricating-return plates 5 adjacent on both sides of the wheel to the ring gear and part of the wheel hub, on the edges of the plates 5 facing the tooth m 2, slots are made (not shown). The plates 5 are mounted motionless relative to the wheels 1 rotating during operation, by means of a fastener 6, these plates being mounted with an inclination relative to the ends 3 of the teeth 2, at an angle of 5 ... 10 in the direction opposite to the direction of movement of the plates.

This lubricating device operates as follows.

In the process of rotation of the wheel 1, the plate 5 sequentially takes positions I, I, 111. Deviating from its lower part with slots under the influence of contact with teeth 2. In this case, the lubricant 7 located on the end surfaces 3 of the teeth 2 (position I ) is captured by the plate 5 (position II) and transferred to the working surfaces of the 4 teeth 2 (position HI). The presence of the angle of inclination of the plates (angle d) relative to the end surfaces 3

of teeth 2 makes it possible to contact the plate 5 with the working surface of each tooth most fully and for a long time, the contact between them starts at the point closest to the middle of the working surface 4 of tooth 2 and continues without interruption to the edge of the tooth (intersection of the working 4 and the end face 3).

This design is intended primarily for reverse gears. In the case of reverse gear, a mechanism for changing the angle of inclination of the plate in the opposite direction can be provided.
