The invention discloses a
lubricant circulating device based on a sliding bearing, as well as a manufacturing process of the
lubricant circulating device. The
lubricant circulating device essentially consists of a bearing bracket, a guide base and an
oil tank; an
oil transportation duct which is connected to a port of a cold oil inputting
pipe penetrates a duct mounting hole of the
oil tank and is connected to a thread hole of the guide base, and is communicated with a cold oil storing cavity; a hot oil outputting
pipe is connected to the
oil tank and is communicated with an oil returning hole, thereby forming a
system-cold oil-hot oil / cold oil-lubricant circulating-inputting / outputting loop; meanwhile, under the
synchronous control of various corresponding equipment, the scheme of arranging the lubricant circulating inputting / outputting loop
system is implemented. Through the lubricant circulating device, the sliding bearing which is matched with the motor, the water pump and other host equipment is not only compactly structured but is adaptive to the high-speed operation of the host equipment, and the sliding bearing cannot change the connecting and mounting size of the original
machine and can ensure the circulation of the lubricant; the bearing bush can not generate heat; the equipment
system is stable, reliable and safe in operation; the lubricant circulating device is suitable to be used as a supporting product of various
power equipment, especially for as a supporting product of various heavy-load
engineering machineries.
