Description
Technical field
The utility model belongs to chain saw technical field, particularly relates to a kind of lubricant oil output unit.
Background technique
Chain saw be for lumbering, the power tool of beta pruning and producing material.Under working condition, the chain saw of chain saw needs to carry out lubricated.The mechanically operated pump oil such as worm gear, the worm screw mode that the many employings of existing chain saw oil supplying device are traditional, complicated structure, processing cost and the assembly cost of component are higher.
Summary of the invention
The utility model provides a kind of lubricant oil output unit, is intended to solve one of above-mentioned technical problem of the prior art at least to a certain extent.
The utility model realizes like this, a kind of lubricant oil output unit, comprise the pump housing, oil inlet pipe, oil outlet tube, pump cover, pulsed tube and pumping diaphragm, the oil-feed side of the pump housing is located at by described oil inlet pipe, the fuel-displaced side of pump cover is located at by described oil outlet tube, described pump cover is located at above the pump housing, and described pulsed tube is located on pump cover, and described pumping diaphragm is located between pump cover and the pump housing.
The technological scheme that the utility model embodiment takes also comprises: described oil inlet pipe and oil outlet tube form oil-feed path and fuel-displaced path in the pump housing, pump chamber and pulse chamber is also comprised between described pump cover and the pump housing, described pump chamber is positioned at below pump cover, described pulse chamber is positioned at above pump cover, and described pump chamber is connected with oil-feed path and fuel-displaced path respectively.
The technological scheme that the utility model embodiment takes also comprises: also comprise pulsed tube, and described pulsed tube is located on pump cover, and one end of described pulsed tube is connected with pulse chamber, and the other end is connected with chain saw engine crankcase.
The technological scheme that the utility model embodiment takes also comprises: also comprise one-way valve, between the oil-feed path that the oil inlet pipe that the pump housing is located at by described one-way valve is connected with pump chamber.
The lubricant oil output unit of the utility model embodiment forms transmission of power by pulse pressure, relative to the lubricant oil output unit of traditional worm and gear transmission of power, its part cost with and assembly cost reduced largely, there is better economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lubricant oil output unit of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, is the structural representation of the lubricant oil output unit of the utility model embodiment.The lubricant oil output unit of the utility model embodiment comprises oil inlet pipe 1, oil outlet tube 2, pulsed tube 3, pump cover 4, the pump housing 5, pumping diaphragm 6, one-way valve 7; Wherein, the oil-feed side of the pump housing 5 is located at by oil inlet pipe 1; The fuel-displaced side of pump cover 4 is located at by oil outlet tube 2, and in the pump housing 5, forms oil-feed path (not shown) and fuel-displaced path (not shown) by oil inlet pipe 1 and oil outlet tube 2; Pump cover 4 is located at above the pump housing 5, and pumping diaphragm 6 is located between pump cover 4 and the pump housing 5, and what described pump cover 4 and the pump housing 5 inside are formed spatially separates down, forms pump chamber 7 and pulse chamber 8 respectively; Pump chamber 7 is connected with oil-feed path and fuel-displaced path respectively and carries out oil storage, between the oil-feed path that the oil inlet pipe 1 that the pump housing 5 is located at by one-way valve 9 is connected with pump chamber 8.Pulsed tube 3 is located on pump cover 4, and one end of pulsed tube 3 is connected with pulse chamber 8, and the other end is connected with chain saw engine crankcase (not shown) inner space.
The working principle of the lubricant oil output unit of the utility model embodiment is: lubricant oil is by entering in the pump chamber 7 in the pump housing 5, the pressure pulse produced in crankcase during rotation chain saw engine crank is delivered in pulse chamber 8 through pulsed tube 3, the pumping diaphragm 6 between pump cover 4 and the pump housing 5 is made to produce vibration by pulse pressure, allow the space of pump chamber 7 changes and mineralization pressure is poor, thus lubricant oil is sucked from oil inlet pipe 1, and pump from oil outlet tube 2 after pump chamber 7; And can under the effect of pressure difference, pass through the unidirectional control of one-way valve 9 or regulate the oil pump capacity of lubricant oil output unit under chain saw idling mode.
The lubricant oil output unit of the utility model embodiment forms transmission of power by pulse pressure, relative to the lubricant oil output unit of traditional worm and gear transmission of power, its part cost with and assembly cost reduced largely, there is better economic benefit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
