Abstract

The invention discloses a multi-actuating travel and return travel irregularly-shaped wheel lubricating grease delivery device, which comprises piston cylinders, pistons and piston rods. Resetting springs sleeved on the piston rods are arranged in the piston cylinders. The device also comprises a square rack. An input shaft is fixedly arranged on the middle part of the rack. A plurality of irregularly-shaped wheels are arranged at an equal interval on the input shaft. A frame fixedly arranged on the rack is arranged outside each irregularly-shaped wheel. The piston cylinders are symmetrically arranged on the rack on the left and right sides of each frame. The end parts of the piston rods matched with the piston cylinders are fixedly arranged on the lateral surfaces of the frames through capped round pins. A fixed shaft is arranged on the lower part of each frame, and penetrates through a guide hole in the bottom of the frame. Each irregularly-shaped wheel consists of three small wheels which are arranged at an equal interval of 120 degrees. Mounting angles of adjacent irregularly-shaped wheels which are arranged at the equal interval on the input shaft are differentiated by 40 degrees. When the irregularly-shaped wheels rotate a circle, the pistons reciprocally move for three times, so that a high-flow stacking fold can be increased, and the non-uniformity of flow of the delivery device can be reduced. The device is simple in structure, uniform in flow and high in stability, and the fluctuation of the flow can be effectively reduced.

Description

technical field [0001] The invention relates to a multi-push backstroke special-shaped wheel grease delivery device, in particular, it is suitable for low-cone-penetration grease delivery. Background technique [0002] Grease has complex rheological characteristics. When conveying at low speed, its viscosity is high due to the effect of non-directional soap fiber fragments, making it difficult to convey; as the shear speed increases, the soap fiber itself will break or break, and its viscosity will decrease. , the transportation resistance is reduced, which is beneficial to transportation; after the shear speed stops, the structural skeleton begins to recover again, and the resistance will increase again when it is transported again. Therefore, the unstable delivery flow will cause the resistance to fluctuate from time to time, which is extremely unfavorable to the transportation process. For the existing lubricating grease conveying device, the grease suction port and the ...
