SU1668895A1 - Lubricating grease device for bearings - Google Patents

Abstract

The invention relates to mechanical engineering and m. Used to fill bearings with lubricant, such as anti-friction. The purpose of the invention is to increase the purity of the filling of the bearing and the exclusion of subsequent grinding operations. The device contains a means of injection of lubricant (SNS), a dispenser, means of extrusion of lubricant (CBC), means of moving the dispenser from the position of injection to the position of extrusion. SNA is made in the form of a power cylinder 2, a tube 3 with a hole 4 and a control cylinder 5 with a shut-off valve 6. The cut-off device has an aperture 7. The power cylinder is filled with grease. The dispenser is made in the form of glass 9. In the bottom of the glass there are a hole and half-ring slots. The dispenser port communicates with the SNS orifice. The dispenser displacement means comprises a ram cylinder with a piston which interacts with the dispenser through a rod. SVS includes a cylinder 15 with a piston and a rod. Plate 16 has semi-annular slots similar to slots in the dispenser. Bearing 17 is mounted on the bottom plate. After the lubricant enters the dispenser, it moves to the extrusion position of the lubricant. CBC acts on the metering piston. Lubrication through the half-ring gap in the plate enters the bearing. 1 hp ff, 3 ill.

lubricant (SNS), metering device, extrusion of lubricant (C B C), means for moving the metering device from the discharge position to the extrusion position, SNS is made in the form of a power cylinder 2, tube 3 with a hole 4 and control cylinder 5 with a cutter 6. The cutter has a hole 7. The power cylinder is filled with grease. The dispenser is made in the form of glass 9. In the bottom of the glass there are a hole and half-ring slots. The dispenser port communicates with the SNS orifice. Vehicle

The invention relates to mechanical engineering and can be used in the manufacture of bearings for laying grease in them, for example, an antifriction self-lubricating material.

The purpose of the invention is to increase the purity of the filling of the bearing and the elimination of subsequent stripping operations.

Figure 1 shows a diagram of the device; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The device comprises means for injecting lubricant, a metering device, means for squeezing out lubricant, and means for moving the metering device from the injection position to the extrusion position.

The means for injecting lubricant is placed on the plate 1 and consists of a power cylinder 2 with a piston, a tube 3 with an aperture 4 and a control cylinder 5 with a slam-shut 6, which has an aperture 7 similar to the aperture of the tube. The chamber formed by the ram, piston and tube is filled with lubricant.

The dispenser is made in the form of a glass 8 with a piston 9 and is mounted on the top plate 10. In the bottom of the glass, an opening 11 and half-ring slots 12 are made, the dispenser opening communicating with the opening 4 of lubricant injection means. The stop screw 13 interacts with the dispenser piston and is designed to regulate the volume of the chamber formed by the glass and the piston. This volume corresponds to the volume of the bearing cavity filled with grease,

The means for moving the dispenser from the injection position to the extrusion position is made in the form of a power cylinder 14 containing a chamber with a piston which interacts with the dispenser,

The lubricant extrusion means includes a piston cylinder 15. In the stove

The doeatha contains a power cylinder with a piston, which interacts with the dispenser through a rod. SVS includes a cylinder 15 with a piston and a rod. Plate 16 has semi-annular slots similar to slots in the dispenser. Bearing 17 is mounted on the bottom plate. After the lubricant enters the dispenser, it moves to the extrusion position of the lubricant. CBC acts on the metering piston. Lubrication through the half-ring gap in the plate enters the bearing. 1 hp f-ly, 3 ill.

16 there are semi-annular slots similar to the slits of the dispenser.

The bearing 17 is placed on the bottom plate 18 opposite the half-ring slots and

supplied to the lubrication zone with the help of a cylinder 19 along guides 20.

The device works as follows.

Pre-assembled and connected to the piston rod of the means for moving the dispenser, a replaceable dispenser in accordance with the size of the bearing to be filled and adjust the volume of the dispenser chamber with a screw 13. Then set

replaceable plate 16 and fix the distance between the guides 20 taking into account the size of the bearing 17. Also install a time relay for automatic opening and closing of the opening 4 with a slam-shut 6,

When the cutter 6 opens the channel 4 means for injecting lubricant under the action of the pressure of compressed air in the sub-piston chamber of the power cylinder

2 fills the dispenser. Then, using the power cylinder 14, the cup 8 is moved to the extrusion position, i.e. on the plate 16. Under the action of the control pressure of the air, the piston 15 of the means of extrusion of lubricant is lowered and the lubricant is forced out of the metering device into the bearing 17 through the semi-circular slots in the plate. After that, the dispenser returns to the pumping position.

The application of the proposed device allows to ensure high quality and cleanliness of the bearing filling due to the exclusion of grease on the bearing.
