Description

Speed reducer oil sump warehouse-dividing lubricating system

Technical Field

The utility model relates to a lubricated technical field of speed reducer, concretely relates to speed reducer oil bath divides storehouse lubricating system.

Background

The speed reducer needs good lubrication and performs good heat exchange in time when working, and a lubrication system is an indispensable component for normal work of the speed reducer. In the traditional design, the speed reducer generally adopts an oil bath lubrication mode or a pressure oil supply lubrication mode, and the two lubrication modes have the advantages and the disadvantages respectively and are stated as follows:

oil bath lubrication: a certain amount of lubricating oil is injected into the speed reducer, and the gear part is directly immersed in the lubricating oil; the speed reducer is provided with an oil inlet and an oil outlet which are respectively connected with an oil supply port and an oil return port of the lubricating device to form a closed circulating system, and when equipment runs, high-temperature lubricating oil in the speed reducer is cooled by a lubricating station and then enters the speed reducer. The lubricating mode has sufficient oil quantity and timely heat dissipation, and the flowing lubricating oil can carry away part of impurities in the speed reducer and is filtered by the lubricating device, so that the gear is sufficiently and reliably lubricated. The lubricating oil is not suitable for shutdown maintenance in alpine regions or in winter, the lubricating oil is very easy to freeze and adhere to the gear and the box body at low temperature and is not easy to clean, and meanwhile, the lubricating oil is inconvenient to replace.

Pressure oil supply and lubrication: the speed reducer is provided with a lubricating station with an oil tank, and lubricating oil is pumped and distributed to each lubricating point in the speed reducer at a certain pressure through the lubricating station and then returns to the oil tank from an oil return port for cooling and filtering. The lubricating mode can take away heat, and the pressure oil can wash away and filter out metal particles on the friction surface. The gear lubricating device has the disadvantages that the lubricating oil quantity and pressure of each point must be monitored, the gear is guaranteed to be reliably lubricated, an output pipeline is complex, the requirement on oil products is high, otherwise, an oil way is easily blocked, and the gear cannot be lubricated timely and is damaged.

In mechanical transmission, lubrication can reduce transmission friction, energy loss and mechanical wear. Therefore, whether effective lubrication of the transmission components can be ensured is a key factor influencing the precision of mechanical movement and the service life. The conventional speed reducer has the advantages that the lubricating oil levels are consistent, the oil consumption is large, and the loss and the oil temperature caused by oil stirring are high; the speed reducer can the internal oil charge of control box for balancing the heat power, because the speed reducer operation back of getting up, can produce a large amount of heats, leads to the temperature to rise, and liquid is great than heat, and the heat preservation ability is stronger, and difficult heat dissipation cooling, if the shang guan is too much, just can lead to the speed reducer temperature to constantly rise, surpasss the operating temperature that the speed reducer allows. Therefore, the reduction gear box reduces the oil amount in the box body in order to balance the thermal power, so that the high-level bearing cannot be lubricated.
