Description

A kind of engine torque extracting machine with built-in oil leab
Technical field
The utility model belongs to diesel engine technologies field, is specifically related to a kind of engine torque extracting machine with built-in oil leab.
Background technique
In the application of heavy-duty engine engineering machinery, general needs rearmounted power take-off drives the hydraulic equipment of engineering machinery to support functions such as turning to.Power take-off assembly includes the precision partss such as bearing, and bearing in order to improve the operating life of bearing, needs machine oil to carry out lubricating bearings under being generally operational in high rotating speed, high hot applied environment.
Present stage is generally lubricated to the bearing in power take-off assembly by the mode of external oil pipe, because engineering machinery vehicle frame kind is many, be difficult to during coupling avoid oil pipe and vehicle frame or other part to interfere, in order to realize coupling, need to design multiple oil pipe, add motor complete machine, after-sales service cost.
In addition, because engineering machinery applied environment is relatively severe, external oil pipe is difficult to avoid because colliding with, foreign impacts and occur breakage, and oil leakage risk is very high, and in high temperature environments, the machine oil of leakage can fire hazard, brings serious potential safety hazard.
Summary of the invention
The purpose of this utility model provides for the problems referred to above the engine torque extracting machine with built-in oil leab that a kind of structure is simple, effectively can avoid oil leakage.
The technical solution of the utility model is achieved in that the engine torque extracting machine with built-in oil leab of the present utility model comprises housing, shaftgear, oil pocket, fore bearing, rear bearing, boss is established at housing forward end, boss there is the oil input channel of straight-through oil pocket, the external port of oil input channel is closed by sealing plug assembly, the front-end face of boss has transition oil duct lead to oil input channel, transition oil duct is corresponding with the oil outlet on backgear room.
Described oil input channel is stepped, and its inner side oil input channel diameter close to oil pocket is 2 ~ 4mm, and outside it, oil input channel diameter is 7 ~ 9mm.
Described sealing plug assembly comprises plug screw and O RunddichtringO.
Advantage of the present utility model:
The utility model is by built-in oil duct, machine oil with certain flow, pressure is ejected in power take-off assembly shell cavity by cylinder body main oil gallery, thus the lubrication realized bearing, this lubricating system effectively can reduce the risk of oil leakage, fully excavates the possibility of each inner body oil duct, effectively reduces motor external bustle pipe number of packages amount, improve level of integration, improve motor to the suitability of different vehicle frame, reduce complete machine, after-sales service cost simultaneously, improve the competitive ability of motor.
Accompanying drawing explanation
Fig. 1 is the built-in oil input channel schematic diagram of power take-off of the present utility model.
Fig. 2 is the stepped oil duct schematic diagram of the utility model structure.
Fig. 3 is the built-in back oil road schematic diagram of power take-off of the utility model structure.
Fig. 4 is power take-off transition oil duct and the backgear room connection diagram of the utility model structure.
Embodiment
The utility model is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is built-in oil input channel overall schematic of the present utility model: the utility model comprises housing 1, shaftgear 2, oil pocket 3, fore bearing 4, rear bearing 5, it is characterized in that: establish boss 6 at housing forward end, boss 6 there is the oil input channel 8 of straight-through oil pocket 3, the external port of oil input channel 8 is closed by sealing plug assembly 9, the front-end face of boss 6 has transition oil duct 7 lead to oil input channel 8, transition oil duct 7 is corresponding with the oil outlet on backgear room.
According in figure shown in arrow, machine oil flows through transition oil duct 7, oil input channel 8 successively from backgear room oil outlet, finally by oil pocket 3 in the oil injection of certain flow, pressure to power take-off housing, thus realizes the lubrication to fore bearing 4, rear bearing 5.
Fig. 2 is the stepped oil duct schematic diagram of the utility model structure: described oil input channel 8 is for stepped, and its inner side oil input channel 8b diameter close to oil pocket 3 is 2 ~ 4mm, and outside it, oil input channel 8a diameter is 7 ~ 9mm.Stepped oil duct can avoid motor main oil gallery pressure to decline, and can improve the injection pressure to power take-off simultaneously.
Described sealing plug assembly 9 comprises plug screw 9a and O RunddichtringO 9b.
Fig. 3 is the built-in back oil road schematic diagram of power take-off of the utility model structure:
According in figure shown in arrow, flow directly to outside power take-off housing 1 by the gap of fore bearing 4 after part machine oil completes lubrication, finally flow in oil sump, enter the built-in back oil road 10 of power take-off housing by the gap of rear bearing 5 after a part of machine oil completes lubrication in addition, finally flow in oil sump.
Transition oil duct 7, stepped oil input channel 8, power take-off housing back oil road 10 are positioned at power take-off housing 1, wherein power take-off housing back oil road 10 is shaped when power take-off housing 1 is cast, and in power take-off housing, oil pocket 3 is made up of fore bearing 4, rear bearing 5 and power take-off housing 1 inwall.
Transition oil duct 7 and stepped oil input channel 8 are shaped by machining, form one section of large aperture oil duct 8a and section small aperture oil duct 8b by machining.Stepped oil duct 8 machines rear needs and installs a sealing plug assembly 9 to seal stepped oil duct at power take-off housing 1.
Fig. 4 is power take-off transition oil duct and the backgear room connection diagram of the utility model structure.
Above-mentioned transition oil duct 7 is by assembly relation, and just in time connect backgear room 12 oil duct oil outlet 12a, the junction plane of transition oil duct and backgear room oil duct is sealed by an embedded sealing gasket 11.
Machine oil with certain flow, pressure in the oil outlet 12a of backgear room 12 is ejected into oil pocket 3 in power take-off housing by transition oil duct 7, stepped oil input channel 8, thus realizes the lubrication to bearing.
After machine oil completes lubrication, by Bearing gaps, the built-in back oil road of power take-off housing, by machine oil water conservancy diversion in engine sump tank.
The utility model can be applicable in the power take-off lubrication applications of 13 liters of automatically controlled and mechanical engines.
