Gear is an important part in the complete crushing homework for roller crusher, if gears can't run smoothly, the material can not be crushed, and the lubrication is also an indispensable part for smoothly running of gears for a long time. Thus, let's talk about how to choose the right gear lubrication oil for roller crusher, and what are the factors that affect the choice of gear lubrication oil?
If lubrication does not reach the designated position, it will affect the normal operation, even damage the equipment. If choose improper lubricant, it will affect the normal operation as serious as without a good lubrication. There are many factors that can affect the choice of gear lubricant, they are as follows.
1. Load (pressure)
High viscosity lubrication oil can resist even heavier load and the collision friction between metals than the low viscosity lubrication oil. Therefore, the machine with low load should use low viscosity lubrication oil, with heavy load should use high viscosity lubrication oil
2. Speed
The faster the gear sliding and the rotation speed, the less time of lubricant enter into gears. Moreover, the lubrication oil under high speed rotation is easy to caking. In this way, after taking comprehensive consideration, the low speed rotating gear use high viscosity oil, the high speed rotating gear use low viscosity oil.
3. Temperature
When the temperature becomes low, the lubrication oil will become thick; when the temperature becomes high, the oil will become thin. Therefore, under the condition of high temperature, should use thick lubrication oil to avoid dry friction between metals, under the situation of low temperature, use low viscosity lubrication oil.
4. Impact Load
When equipment engine gives dynamic load, it requires heavy lubrication oil to prevent boundary lubrication caused by instant rupture of the oil film, little lubrication oil can leave. In this case, you need lubrication oil which contains extreme pressure additives.
5. Gear Type
If use straight tooth, helical teeth, herringbone gear and bevel gear, the roller crusher will generate effective oil film when the roller crusher is sliding and rotating so as to reduce the direct geared between two wheels. On the turbine vortex rod and transmission device like un-parallel shaft, the relative sliding direction is bad for maintaining oil film. In this transmission device, boundary lubrication often appears.
Since each factor will affect the selection of gear lubrication oil, the customer should know the relative factors before selection, taking comprehensive considering to choose the proper lubrication oil.
