Abstract
The utility model discloses a loader gearbox steering pump power of getting mouthful bearing lubricating arrangement, include box, steering pump drive shaft, double -screw bolt, packing ring, nut, steering pump, bearing frame, bearing and connect the food tray, connect the food tray to establish the inner wall that lies in the steering pump hole at the box, should connect the highest oil storage point of food tray to lie in the bearing ball position, the integral key shaft and the splined hole of steering pump drive shaft of steering pump are connected and are locked on the upper portion of box through double -screw bolt, packing ring, nut, and the steering pump drive shaft is equipped with the bearing, and the bearing is installed on supporting the lateral wall in the box the bearing frame and through the bearing frame. This structure loader gearbox steering pump power of getting mouthful bearing lubricating arrangement has that bearing lubrication is effectual, the device production maintenance cost is low, long service life's advantage, has solved prior art and has installed because of the bearing and cause lubricated insufficient problem that causes bearing failure at the gearbox lateral wall.
Description
Technical field
This utility model relates to loading machine gearbox, is specifically related to loading machine gearbox steering pump power taking mouth bearing-lubricating device.
Background technology
The power of China's loading machine steering is essentially from change speed gear box at present, steering pump splined shaft in change speed gear box is connected with steering pump drive shaft splined hole and is locked on casing by bolt, and steering pump drive shaft two ends and are positioned at the top of change speed gear box by bearings on wall box.Have the disadvantage that when change speed gear box works, gear rotates the top that lubricating oil is thrown to casing, a part of lubricating oil directly drops in casing, a part of lubricating oil, along the inwall of casing toward dirty, because bearing is arranged in change speed gear box sidewall, is not easily accessible bearing along cabinet wall toward dirty lubricating oil, bearing is made to can not get the lubrication of abundance, cause the fault of bearing damage, reduce the reliability of change speed gear box, considerably increase the operation and maintenance cost of equipment.
Summary of the invention
The purpose of this utility model is to provide that a kind of bearing lubrication is effective, equipment making maintenance cost is low, the loading machine gearbox steering pump power taking mouth bearing-lubricating device of length in service life, solves prior art and causes the insufficient problem causing bearing damage of lubrication because bearing is arranged on change speed gear box sidewall.
For realizing object above, this utility model loading machine gearbox steering pump power taking mouth bearing-lubricating device includes casing, steering pump drive shaft, stud, packing ring, nut, steering pump, bearing block, bearing and oil drain pan；Described oil drain pan is located at casing and is positioned on the inwall turning to pumping holes, and the highest oil storage point of this oil drain pan is positioned at bearing ball position；The splined shaft of described steering pump is connected with the splined hole of steering pump drive shaft and passes through stud, packing ring, nut check on the top of casing, and steering pump drive shaft is equipped with bearing, and bearing is arranged in bearing block and is supported on the sidewall of casing by bearing block.
The structure design of said structure loading machine gearbox steering pump power taking mouth bearing-lubricating device has the following characteristics that
1, casing turns to increases oil drain pan on the inwall of pumping holes, gear rotation is thrown to the lubricating oil part on casing top and drops in oil drain pan, and a part flows downstream in oil drain pan along cabinet wall.Make bearing obtain sufficient lubrication, reduce the fault of bearing damage, improve the reliability of change speed gear box.
2, the highest oil storage point of oil drain pan is positioned at bearing ball position, making ball be fully contacted with lubricating oil, the lubricating oil that will be attached to during bearing rotary on ball takes oil drain pan out of, takes away the heat that bearing rotary produces simultaneously, improve the service life of bearing, ensure that change speed gear box quality well.
This utility model loading machine gearbox steering pump power taking mouth bearing-lubricating device is by turning to increase oil drain pan on the inwall of pumping holes at casing, the highest oil storage point of oil drain pan is positioned at bearing ball position, solve because bearing is arranged in change speed gear box sidewall, gear rotates the lubricating oil got rid of and is not easily accessible bearing, bearing is made to can not get the lubrication of abundance, the problem causing bearing damage, improves the reliability of change speed gear box, greatly reduces equipment operation maintenance expense.
Accompanying drawing explanation
Fig. 1 is this utility model loading machine gearbox steering pump power taking mouth bearing-lubricating device structural representation.
Fig. 2 is cabinet wall partial schematic diagram in this utility model loading machine gearbox steering pump power taking mouth bearing-lubricating device.
Reference: casing 1, steering pump drive shaft 2, stud 3, packing ring 4, nut 5, steering pump 6, bearing block 7, bearing 8 and oil drain pan 9.
Detailed description of the invention
With detailed description of the invention, this utility model loading machine gearbox steering pump power taking mouth bearing-lubricating device is described in further detail below in conjunction with the accompanying drawings.
The steering pump power taking mouth bearing-lubricating device of this utility model loading machine gearbox shown in Fig. 1 ~ Fig. 2 includes casing 1, steering pump drive shaft 2, stud 3, packing ring 4, nut 5, steering pump 6, bearing block 7, bearing 8 and oil drain pan 9；Described oil drain pan 9 is located at casing 1 and is positioned on the inwall turning to pumping holes, and the highest oil storage point of this oil drain pan 9 is positioned at bearing 8 ball position；The splined shaft of described steering pump 6 is connected with the splined hole of steering pump drive shaft 2 and passes through stud 3, packing ring 4, nut 5 are locked at the top of casing 1, steering pump drive shaft 2 is equipped with bearing 8, and bearing 8 is arranged in bearing block 7 and is supported on the sidewall of casing 1 by bearing block 7.
During work, gear rotates the top that the lubricating oil of casing 1 bottom is thrown to casing 1, and a part drops in oil drain pan 9, and a part flows downstream in oil drain pan 9 along casing 1 inwall, and remaining drops back in casing 1；Owing to the highest oil storage point of oil drain pan 9 is positioned at bearing 8 ball position, make ball be fully contacted with lubricating oil, make bearing 8 obtain the lubrication of abundance；On the other hand, will be attached to the lubricating oil on ball when bearing 8 rotates and take oil drain pan 9 out of, band bearing running 8 rotates the heat produced simultaneously, advantageously reduce the fault rate that bearing 8 damages, improve the service life of bearing 8, improve the reliability of change speed gear box, greatly reduce equipment operation maintenance expense.
