Description
Technical field
The utility model belongs to winning equipment field, particularly a kind of stroke bushing of transmission shaft endoporus wear measurement device.
Background technology
Stroke apparatus is a kind of device by both sides transmission shaft transmitting torque and rotating speed, because being outer side drive creeper tread, every side transmission shaft rotates, therefore on the instantaneous force analysis of transmission shaft, it is fulcrum that regarding as of can being similar to be take the little lining of inner side transmission shaft, stress point and the arm of force and transmission shaft, the stress point of wheel junction and two equilibrant that the arm of force is combined into lever of Large lining outside transmission shaft.Analyze thus, in daily production operation process, because stroke apparatus is all the time in high load capacity heavy duty and frequent motion state, therefore very easily cause Large lining endoporus outside stroke transmission shaft to produce wearing and tearing.Yet in the cautious process of everyday devices, because traveling process jolts vibration greatly, outside transmission shaft, lining diameter of bore wear extent is in the time of 1-10 millimeters, on equipment point-detecting personnel range estimation and sense organ, be difficult to measure and differentiate the wear extent of lining endoporus outside transmission shaft, now owing to having there is gap in transmission shaft and lining endoporus, in operational process, the dust that creeper tread takes up very easily thus gap location enters in the gap of transmission shaft and lining.Not only easily stop up thus transmission shaft oil leab, the wearing and tearing of the neck bush endoporus that more easily drives up.Meanwhile; when bushing of transmission shaft endoporus wear extent expands gradually; also cause transmission shaft and the engagement of pitch wheel deflection; also very easily cause thus adjacent strength of gear uneven produce crack a joke, the fault such as broken teeth and off-axis occurs; cause thus equipment failure to be shut down, affect device fabrication operation.
Summary of the invention
The purpose of this utility model is to provide a kind of stroke bushing of transmission shaft endoporus abrasion amount measuring device, obtains stroke bushing of transmission shaft endoporus wear extent, thus for use and the repair work of equipment provides foundation, guarantee equipment intact effectively and carrying out in order of producing.
The purpose of this utility model realizes by following technical proposals.
Stroke bushing of transmission shaft endoporus wear measurement device of the present utility model, is characterized in that by three measuring sticks and the vertical angle measurement chi that three measuring sticks match is therewith formed,
It is right cylinder that one end of the first measuring stick in three described measuring sticks is provided with the screw thread, the other end that match with the oily stifled thread size of transmission shaft end, one end of the second measuring stick and the 3rd measuring stick is provided with the screw thread matching with two the oily stifled thread sizes of axle stub, the other end is right cylinder
Described vertical angle measurement chi is comprised of the dip stick that is provided with the base plate of two pilot holes and phase right angle, one end connection of base plate therewith,
Two pilot holes of described base plate are rectangle mounting hole, and these two rectangle mounting holes and described the second measuring stick and the right cylinder of the 3rd measuring stick are slidably matched,
Centre distance between two described rectangle mounting holes equals two adjacent stifled centre distance of axle head oil of propping up wheel shafts,
The length of described base plate equals the axle head You Du center of transmission shaft to the distance size in the stifled outside of axle head oil of lateral branch wheel shaft.
The cylinder diameter D=10 millimeter of three described measuring sticks, length L=50 millimeter.
The thickness of the base plate of the vertical angle measurement chi of described dip stick is 10 millimeters, is highly 40 millimeters, and the main scale measuring unit of vertical angle measurement chi is millimeter.
The measuring method of this stroke bushing of transmission shaft endoporus wear measurement device comprises the steps:
1) three measuring sticks are tightened on respectively in the axle head oil plug-hole of transmission shaft and adjacent with transmission shaft two wheel shafts,
2) measuring stick of take on two wheel shafts, as point of fixity is installed, is overlapped the slot of a corresponding wheel shaft on the base plate of vertical angle measurement chi respectively in two measuring sticks that inject an axle stub, and is abutted against axle head end,
3) now take the center line that the main scale of vertical angle measurement chi aims at transmission shaft end measuring stick is to detect target, the altitude datum size while measuring respectively the transmission shaft standard assembling of power shovel stroke both sides, and do archives and retain raw readings,
4) in power shovel operational process, by the 3rd) measuring method of step, in good time in the cautious process of equipment, respectively the vertical range of power shovel both sides stroke transmission shaft and two wheel shaft lines is detected, and the numerical value of detection is calculated to comparison by following formula, after converting according to the similar right-angle triangle tangent formula of same acute angle, obtain:
The variable quantity that the greatest wear amount of transmission shaft Large lining endoporus equals transmission shaft end measuring stick height than the actual known distance of uploading two lining outer ends of moving axis is that the height value of vertical angle measurement chi random measurement deducts height value that raw file retains than the distance of upper known transmission shaft little lining outer face and transmission shaft end measuring stick.
The technical solution of the utility model is by making vertical angle measurement chi and three the threaded measuring sticks that are provided with two pilot holes, location by a side transmission shaft and adjacent two wheel shafting oil plug-holes, the vertical drop of take between transmission shafting oil plug-hole center line and the connecting line of two wheel shafting oil plug-hole center lines is master reference size, by the variation of the transmission shaft difference in height that in use lining endoporus wear extent causes, the comparing and converting of the numerical value recording with this measurer and master reference size, obtain the actual value of the wear extent of bushing of transmission shaft endoporus, thereby for equipment use and maintenance provides reliable equipment control foundation.
The utlity model has following advantage: this kind of stroke bushing of transmission shaft endoporus abrasion amount measuring device, by the random installation in daily cautious process, detect, can obtain in time the wear extent of bushing of transmission shaft endoporus, measurer is made simple, measuring process flexible and convenient, can effectively improve cautious work efficiency thus, reduce maintenance labour intensity, effectively save production maintenance cost.
