Description
Technical field
The utility model belongs to the measurement technology field of bearing protrusion amount, and what relate generally to is the ordinary surveying device of assembly angular contact ball bearing protrusion amount.
Background technology
The assembly angular contact ball bearing, promptly two covers or the above angular contact ball bearing of two covers in accordance with regulations process measurement select assembly to form.With paired duplex angular contact ball bearing is example back-to-back, when bearing assembles,, make its inner ring end face be lower than outer ring wide end surface zero point more than zero millimeters through apolegamy or special processing, this parameter is called as " protrusion amount ", promptly has certain clearance to exist between the end face of two inner rings.After installation applies load, the end face of two inner rings is also contacted, the elimination gap also is close to, and bearing promptly obtains to add in advance axial load.Simultaneously, the outer ring wide end surface of two bearings also is close under the effect of axial force and becomes as a whole.This class bearing is considerable in the demand in machine tool chief axis market.
This shows that this class bearing is in the major technique in when assembling, guarantee that exactly the protrusion amount between the inside and outside circle end face of bearing gets final product in certain scope.Make bearing the time guarantee earlier that in assembling bearing realizes the condition of pre-interference, promptly two of pairing cover bearings are under the measurement load of regulation, and the protrusion amount of its end face that contacts must can both be guaranteed, and just will whether reach requirement through measurement.
The instrument of measuring bearing protrusion amount at present has pneumatic measuring instrument, electrical measuring instrument and mechanical drive measuring instrument, these measuring instruments not only price are generally higher, and the measurement range of every kind of instrument only comprises a size segmentation, can not cover the variation of the new product gauge size section that emerges in an endless stream.Also there is the unsettled defective of the measured value that causes because of the air pressure instability in pneumatic measuring instrument, affects the stable measured value of protrusion measuring.Electrical measuring instrument exists because of requiring good stability to make its mechanism's complexity cause the low problem of efficiency of measurement.The mechanical drive measuring instrument exists the gear train wearing and tearing to lose and causes the measured value problem of unstable.
Summary of the invention
The purpose of this utility model is to propose a kind of ordinary surveying device that measures assembly angular contact ball bearing protrusion amount.Make that its method for measurement is simple and convenient, measurement range is wide, measuring accuracy is stable, efficiency of measurement is high, cheap, be fit to assembly fast in enormous quantities and measure.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it is propped up by measuring table, distortion load, base and meter and table and is configured to, base, meter and table support all are arranged on the measuring table and can move along it, and the lower surface of described distortion load is provided with the clearance fit face that matches with the external diameter of the internal diameter of measured bearing inner ring or outer ring; In the radially position symmetric design of distortion load the following table groove of perforation is arranged, on the excircle of distortion load, be provided with the hand rest groove, the protrusion amount of itself and base conjunction measuring bearing.
The utility model is reasonable in design, and is simple in structure.Because the load constant of its use, so absolute value is measured the duplicate measurements stable accuracy.This load durability height, using method is simple and convenient, only need should load and support base and measure the horizontal sliding on measuring table of gauge outfit dial framework, can finish the absolute value measurement that applies the conformance with standard measuring principle of inside and outside circle height value algebraic difference (protrusion amount) behind the load.This utility model technology has great practical value, especially then has more practical value in large batch of assembly measurement of assembly measurement, the efficient in-situ of rapid reaction trial production of new products and the more weak small business that does not possess complete high price protrusion measuring instrument of strength.
