Abstract
The utility model relates to an oil cooling device for an oil cooling speed reducer, which comprises a gear oil pump, a heat exchanger, an oil inlet pipe and an oil outlet pipe. The oil output pipe is provided with a liquid level protection device which can make the liquid level of the lubricating oil in a gearbox of the speed reducer kept at the required lowest liquid level. By the arrangement of the liquid level protection device in the utility model, the liquid level of the lubricating oil in the gearbox of the speed reducer also can be kept at the the required lowest liquid level under the leakage condition, and the phenomenon that the gears in the speed reducer are meshed in a drying state for a long time also cannot occur, thus, the oil cooling device for the oil cooling speed reducer can effectively prevent damage of the speed reducer caused by the accidental leakage of the oil cooling device, has small investment of the required liquid level protection device, does not need manual inspection and has high reliability.
Description
Technical field
The utility model relates to a kind of oil injection type speed reducer oil cooling device, relates to the oil injection type speed reducer oil cooling device that a kind of usefulness can be protected cold oil liquid level in the reducer gear case specifically.
Background technique
Large-scale speed reducer adopts the oil cooling device to reduce the oily warm of lubricant oil higher in the speed reducer through regular meeting, to improve the stability and the reliability of device operation.This oil cooling device is reached by gear oil pump, heat exchanger usually to be formed into and out of oil pipe, after lubricant oil in the reducer gear case is cooled off through heat exchanger through gear oil pump by oil outlet tube again, enter speed reducer by oil inlet pipe, in this cyclic process, if there is a place (screw thread, flange connection, gear oil pump etc.) leak source to occur, will cause the oil leakage in the speed reducer, long-time unmanned discovery can cause the gear dryness engagement in the speed reducer, even situations such as first grade axis and secondary shaftgear Surface of action burn can occur.How to prevent the fault that the oil leakage point brings reliably, become the difficult point that each large enterprises of puzzlement use the oil cooling device, though the enterprise that has adopts pressure warning unit to address the above problem well, but this solution investment is bigger, and still depend on patrolling and examining closely of operator, reliability is not strong.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of oil injection type speed reducer oil cooling device little, good reliability of investing is provided, and can effectively prevent to cause speed reducer to damage because of the accidental release of oil cooling device.
For achieving the above object; the utility model has adopted following technological scheme: comprise that gear oil pump, heat exchanger reach into and out of oil pipe; the lubricant oil inlet/outlet of reducer gear case is communicated with respectively with into and out of oil pipe; oil outlet tube, gear oil pump, heat exchanger and oil inlet pipe are communicated with the formation loop successively, and oil outlet tube is provided with and can makes reducer gear case lubricant oil liquid level remain on the liquid level protection device of required minimum liquid level.In case the accidental release of oil cooling device can guarantee that the liquid level of the lubricant oil in the reducer gear case remains on needed height, cause damage to prevent the gear dryness engagement for a long time in the speed reducer.
Described liquid level protection device is the fuel reserve tank that is serially connected on the oil outlet tube, and fuel reserve tank is provided with relief opening, and the required minimum liquid level of lubricant oil in the oil outlet height of fuel reserve tank and the reducer gear case is contour.Fuel reserve tank and reducer gear case are connected to form connecting vessels by oil pipe, in case oil cooling device accidental release, the lubricant oil liquid level in the reducer gear case drops to the height of fuel reserve tank oil outlet at most.
Also for being located at the oil exit pipe in the reducer gear case, oil exit pipe is communicated with oil outlet tube described liquid level protection device, and the required minimum liquid level of lubricant oil in the filler opening height of oil exit pipe and the reducer gear case is contour.
As shown from the above technical solution, the utility model is by being provided with liquid level protection device, make that reducer gear case lubricant oil liquid level also can remain on required minimum liquid level under the situation that leakage occurs, the gear dryness engagement for a long time phenomenon in the speed reducer can not occur, can effectively prevent to cause speed reducer to damage because of the accidental release of oil cooling device; And required liquid level protection device investment is little, does not also need manual inspection, good reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the another kind of mode of execution of the utility model.
Embodiment
The utility model oil cooling device is reached and is formed into and out of oil pipe 4,1 and liquid level protection device by gear oil pump 2, heat exchanger 3.As shown in Figure 1; liquid level protection device is a fuel reserve tank 9 that is arranged on the oil outlet tube 1; fuel reserve tank 9 is connected to form connecting vessels in the bottom by oil pipe 7 with reducer gear case 6; fuel reserve tank 9 tops are provided with relief opening 8; the height of relief opening 8 is higher than the highest liquid level of lubricant oil in the reducer gear case 6; the required minimum liquid level of lubricant oil that fuel reserve tank 9 leads in the oil outlet height of oil outlet tube 1 and the reducer gear case 6 is contour, and this minimum liquid level should be able to guarantee to have at least the gear teeth of operative gear 5 to immerse wherein.Lubricant oil in the reducer gear case 6 enters speed reducer 6 by oil inlet pipe 4 after being cooled off through heat exchanger 3 through fuel reserve tank 9, gear oil pump 2 by oil outlet tube 7 again.Because fuel reserve tank 9 is connected to form connecting vessels with reducer gear case 6 by oil pipe 7, in case oil cooling device accidental release, the lubricant oil liquid level in the reducer gear case drops to the height of fuel reserve tank oil outlet at most.
As shown in Figure 2, also for being located at the oil exit pipe 10 in the reducer gear case 6, oil exit pipe 10 is communicated with oil outlet tube 1 liquid level protection device, and the required minimum liquid level of lubricant oil in the filler opening height of oil exit pipe 10 and the reducer gear case 6 is contour.In case oil cooling device accidental release, the lubricant oil liquid level in the reducer gear case 6 drops to the height of oil exit pipe 10 filler openings at most.
