Abstract
The utility model relates to gear detection equipment, in particular to a detection device for deviation of center lines of a gear internal keyway and a tooth crest. The detection device solves the problem that at present, a device capable of measuring relative position deviation of the center lines of the gear internal keyway and the tooth crest does not exist. The detection device consists of a keyway sample plate, a positioning plate, positioning pin shafts and measuring pins, wherein the center line of the keyway sample plate is superposed with the center line of the internal keyway, the center line of the positioning plate is superposed with the center lines of the tooth crest and the keyway sample plate, the center line of one end of the positioning plate is superposed with the center line of the tooth crest, two sides of gear teeth are respectively provided with two measuring pins, the center line of the other end of the positioning plate is superposed with the center line of tooth roots, and the positioning plate and the keyway sample plate are positioned by using the positioning pin shafts. The detection device is used for detecting gear geometric tolerance, and has the advantages of being high in precision, low in cost, simple in structure, simple and convenient in operation, and good in safety.
Description
Technical field
The utility model relates to the gear checkout equipment, the device of specifically a kind of detection of gear internal keyway center line and gear teeth tooth top position of center line deviation.
Background technology
For the gear that the run-in synchronism requirement is in use arranged, the tooth top center line of the designing requirement gear teeth and the keyway center line of bore have the higher form and position tolerance of ratio of precision.At present, prior art does not also have to carry out its relative position deviation the device of quantitative measurment, can't guarantee the run-in synchronism requirement of gear.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art; The pick-up unit of a kind of gear internal keyway and tooth top centerline deviation is provided, and solving does not have a kind of device can be to the problem of gear internal keyway center line with the measurement of tooth top center line relative position deviation at present.
The task of the utility model is to adopt following measure to realize:
The pick-up unit of a kind of gear internal keyway and tooth top centerline deviation; It is characterized in that: said pick-up unit is made up of keyway model, location-plate, alignment pin and measurement pin; The center line and the said gear internal keyway central lines of the said keyway model of making, the central lines of the center line of the said location-plate of making and said gear teeth tips center line and said keyway model, an end of the said location-plate of making; The tooth top central lines of its center line and said gear; And two said measurement pins, the tooth root central lines of the line of said measurement pin center and said gear centre and said gear, the other end of the said location-plate of making are set respectively in the both sides of the gear teeth; The tooth root central lines of its center line and said gear, said location-plate is connected, locatees with said alignment pin with said keyway model.
The utility model can be measured the position deviation of gear internal keyway center line and gear teeth tooth top center line easy, intuitively, effectively; For the run-in synchronism of the gear pairing of gearing, centering, gear provides technical support; Satisfy the synchronous requirement of transmission, and improve the precision of efficiency of assembling and meshing gear greatly, reduce the gear damage and prolong its serviceable life; Reduce the manpower and materials of maintenance; To promoting the total quality and the prestige of product, positive effect is all arranged, have very strong practicality and economy.
Description of drawings
Fig. 1 be the utility model install and use synoptic diagram (front view);
Fig. 2 is the side view of Fig. 1.
The utility model is further described through embodiment below in conjunction with accompanying drawing.
Embodiment
Like Fig. 1, shown in 2; The pick-up unit of a kind of gear internal keyway and tooth top centerline deviation is formed the center line of the said keyway model 1 of making and said gear internal keyway central lines by keyway model 1, location-plate 2, alignment pin 3 and measurement pin 4; The center line of the said location-plate of making 2 and the central lines of said gear teeth tips center line and said keyway model 1; One end of the said location-plate of making 2, the tooth top central lines of its center line and said gear, and two said measurement pins 4 are set respectively in the both sides of the gear teeth; The tooth root central lines of the line and the said gear of 4 centers and said gear centre is sold in said measurement; The other end of the said location-plate of making 2, the tooth root central lines of its center line and said gear, said location-plate 2 is connected, locatees with the said alignment pin 3 of said keyway model 1 usefulness.
The keyway model 1 of the utility model guarantees its center line and keyway central lines through manufacturing accuracy; Be used for confirming the position of gear keyway center line; Location-plate 2 and keyway model 1 usefulness alignment pin 3 location are guaranteed and keyway central lines and extending on the gear teeth tips center line; Can make keyway center line and theoretical tooth top central lines easily; Utilize then clearance gauge measure on the location-plate two measure pin 4 cylindricals apart from keyway over against the deviation of gear teeth both sides flank profil, thereby draw the position deviation of gear internal keyway center line and gear teeth tooth top center line.
The utility model is used for the relative position deviation of detection of gear internal keyway center line and gear teeth tooth top center line; Solved that prior art can't accurately be located and the measurement that causes is inaccurate, processing and assembly precision is difficult to guarantee, gear can't synchronous operated technical matters, the pick-up unit that a kind of precision is high, cost is low, simple in structure, easy and simple to handle, security is good is provided.
The utility model is because the three-point fix of keyway model 1 and location-plate 2, makes internal keyway center line and gear tooth theory tooth top central lines.It is to design and place according to its position of profile combination of gear tooth that three of the utility model are measured pin 4, can measure the deviation of the outer distance of round gear tooth profile of pin through measuring pin 4.
