Abstract
A lubricating system for bearing shoes supporting a drum of a crusher for rotation and defining a lubricating oil basin between an upstream and downstream end, in the direction of rotation, comprises a low pressure oil pump operable to deliver lubricating oil to the upstream end of the bearing shoes during rotation of the drum, a high pressure pump operable to deliver lubricating oil to the basin at the start of rotation, and thermocouples arranged to measure the temperature of the bearing shoes close to their gliding surfaces, the thermocouples controlling the high pressure pump operation in response to a temperature sensed by the thermocouples and exceeding a set value.
Claims10
A lubricating system for bearing shoes having gliding surfaces supporting a heavy element of large diameter for rotation about an axis thereof in one direction, the bearing shoes having an upstream end and a downstream end, in said direction, and defining a lubricating oil basin therebetween, which comprises
- (a) a low pressure lubricating oil pump operable to deliver lubricating oil to the upstream end of the bearing shoes during the rotation of the heavy element,
- (b) a high pressure lubricating oil pump operable to deliver lubricating oil to the basin at the start of the rotation,
- (c) means for operating the high pressure pump, and
- (d) thermocouple means arranged to measure the temperature of the bearing shoes close to their gliding surfaces, the thermocouple means controlling the operating means for actuating the high pressure pump in response to a temperature sensed by the thermocouple means exceeding a first set value.
