The invention discloses a pressing-down type crimping machine for a short fiber production line. The pressing-down type crimping machine comprises crimping rollers, an engine base and a lower swinging arm; a pair of crimping rollers, which rotate by resultant force, are mounted on the engine base and the lower swinging arm; each crimping roller comprises a crimping roller wheel and crimped rolling shafts arranged on the two sides of the crimping roller wheel; and the crimped rolling shafts at the two ends of the crimping rollers are connected with the engine base and the lower swinging arm through rotary mechanisms. By adopting the pressing-down type crimping machine, the problem of a traditional crimping machine that the service life of equipment is short when short fibers are produced is mainly solved; a self-aligning roller bearing is used as a radial loading bearing of equipment and an angular contact ball bearing is used as an axial positioning bearing, so that precision of the crimping rollers is guaranteed when the crimping machine is operated and the playing is not easy to occur; meanwhile, a bearing base mounting manner is abandoned and the bearing is internally mounted by adopting a bearing bush; and in a mounting process, the bearing bush is directly mounted on a mounting base, so that the subsequent installation and overhauling difficulties of the crimping rollers are reduced and accumulated installation errors are reduced.

An intelligent lubricating system for a heavy-duty bearing of a wind power generating set belongs to the technical field of wind turbines. Installed on the base of the engine room, it includes a trigger device and an oil suction and injection pipeline connected to the main bearing. The trigger device includes an action connecting rod and a trigger block. The trigger block is arranged on the outer periphery of the main shaft. One end of the action link is a free end for It is triggered by contact with the trigger block, and the other end is connected to the oil injector. The oil suction and oil injection pipeline includes an oil suction pump, an oil suction filter, a grease storage tank, an oil injector and an oil injection filter connected in sequence. The oil suction pump is connected to the main bearing on the main shaft Oil outlet, the oil outlet pipe of the oil injection filter is connected to the oil injection port of the main bearing to form a lubricating oil circulation; through the rotation of the main shaft, the action connecting rod contacts the trigger block, driving the action connecting rod to reciprocate, and the oil suction pump sucks the lubricating oil flowing out of the main bearing , After being filtered by the oil suction filter, it is stored in the grease storage tank, and then filtered by the oil injector and the oil injection filter, and then returned to the oil injection port of the main bearing for supplementary lubrication. The invention can realize the circulation lubrication of the bearing and improve the service life of the main bearing.

The invention aims at providing an oil and gas spring type self-lubricating compensation floating piston. The oil and gas spring type self-lubricating compensation floating piston comprises a small piston, an automatic lubricating floating piston, a small piston sealing ring and a clamp spring, wherein the small piston is sheathed in a center weight reducing groove of the automatic lubricating floating piston; lubricating oil or lubricating grease is arranged into an oil storage cavity surrounded by the small piston and the automatic lubricating floating piston; the small piston sealing ring is arranged in the small piston in the radial direction, and is matched with the inner wall of a weight reducing hole to form radial sealing; the clamp spring is arranged at the upper end of the weight reducing hole, so as to prevent the small piston from falling down from the automatic lubricating floating piston during high-speed movement; the side surface of the automatic lubricating floating piston is processed with a radial lubricating oil passage and a peripheral lubricating oil passage, a lubricating oil groove is arranged between a sealing ring at the oil side and a sealing ring at the gas side, and the lubricating oil passage is used for guiding the lubricating oil in the oil storage cavity into the lubricating oil tank and a radial gap between the automatic lubricating floating piston and a cylinder body.
