A slider type cardan shaft

Abstract

The invention discloses a slide block type universal shaft, which comprises a flat-head female connector, a tiger mouth semi-connector, a spindle, a transmission shaft, a slide block and a lubricating device, wherein the flat-head female connector is movably connected with the tiger mouth semi-connector through the transmission shaft, and the spindle is arranged on one end surface of the tiger mouth semi-connector; the lubricating device comprises a pendulum device, a pump block, a diverter, a plunger pump and a flow control valve, and the pendulum device comprises a pendulum head, a pendulum rod, a bearing and a pendulum seat; and the pendulum head is in movable contact with a plunger rod of the plunger pump, and the plunger pump, the diverter, lubricating tubing, a tiger mouth semi-connector oil duct, a transmission shaft oil duct and lubricating oil holes are lubricated by lubricating oil. The slide block type universal shaft provided by the invention has the advantages of saving cost, efficiently, timely, quantitatively lubricating each component, and greatly prolonging the service life of the slide block and the transmission shaft.

Description

technical field [0001] The invention relates to a slider type cardan shaft, more specifically relates to a slider type cardan shaft with a lubricating device, and belongs to the technical field of transmission devices. Background technique [0002] The slider-type universal joint shaft is a key equipment component in the main drive system of a rolling mill, and its advantages are high load-carrying capacity and good impact resistance. Slider-type universal joints are prone to sliding friction between sliders, flat joints, half-joints, and transmission shafts during work. Therefore, lubrication between various components is very important and will directly affect the use of the universal joint. life. [0003] At present, the conventional lubrication methods include: dry grease lubrication, manual timing grease filling and external pipeline lubrication. In actual use, the above methods need to be refueled every shift. Due to the harsh operating environment on site, the fillin...

Problems solved by technology

[0003] At present, the conventional lubrication methods include: dry grease lubrication, manual timing grease filling and external pipeline lubrication. In actual use, the above methods need to be refueled every shift. Due to the harsh operating environment on site, the filling amount is often insufficient or small. Oil injection phenomenon, the lubrication efficiency is low, the slider is not sufficiently lubricated, resulting in serious wear, an average of 3 months needs to replace a set of sliders, and the maintenance cost is high
