Description

one

A device for automatic lubrication of conveyor rollers is known. St. 335496, made in the form of a movable carriage with a plunger pump fixed on it and containing a distribution column, at one end of which syringes are mounted, and on the other are cams interacting with the pump plunger, in addition, syringes are made with a head in the form of a plate mounted on the ball joint.

The purpose of the invention is to provide lubrication for traction elements, the lubricating valves of which are located at different distances from the longitudinal axis of the conveyor.

This is achieved by TeiM, that in the device intermediate syringes are used, movably mounted on a rotary rotor, pivotally mounted on a swinging arm.

FIG. 1 shows schematically the described device in plan; in fig. 2 - view along arrow A ia. FIG. one; in fig. 3 is a view along arrow in FIG. 2

The device contains a moving one in the direction of the arrows V ka, a reticule 1 on which the rotating column 2 is mounted, equipped with four syringes 5 with catchers 4.

A rocker arm 6 with a counterweight 7 is mounted on the post 5. At the other end of the rocker arm 6, a rotor 8 is pivotally mounted, on which intermediate syringes 9 with disks 10 and support rollers 11 interacting with guide 12 are mounted axially. Springs 13 hold syringes 9 in the extreme right position. A support 14 is arranged on the post 5 to hold the rotor 8 in the upper idle position.

The device serves to lubricate the traction member, for example, chain 15, the lubrication valves 16 and 17 of which are located at different distances from the longitudinal axis O-O. To supply the lubricant to the valves 16, the rotor 8 rises to the non-operating position and the device operates by supplying lubricant from the syringes 3.

To feed the valves 17, the rotor 8 is lowered until the rollers 11 stop against the guide 12. The protruding ends 18 of the moving chain 15 engage with the disks 10 and rotate the rotor 8. The rocker 6 oscillates and the rollers 11 roll over the guide 12 dvil uts part of the cycle. In this

the output end of the syringe 9 is positioned against the valve 17, and the input end is engaged with the catch 4 of the syringe 3 and drives the column 2 into rotation. At the same time, the output end of the syringe 9 is pressed against the valve 17 and

A lubricant portion is supplied to the last of the syringe 5 via an intermediate syringe 9. At the end of the cycle, the spring 13 returns the syringe 9 to its original position.

Subject invention

Device on aut. St. No. 335496, characterized in that, in order to provide lubrication

elements of the traction organ, the lubricating valves of which are located at different distances from the longitudinal axis of the conveyor, use intermediate syringes movably mounted on a rotary rotor pivotally mounted on a swinging arm.
