The utility model is achieved in that it comprises the measurer axle sleeve, dial gauge is installed on the measurer axle sleeve, the interior body wall of described measurer axle sleeve and the shaft of screw rod are in axial sliding connection, setscrew nut is connected with an end spiral of screw rod, the screw socket end face of setscrew nut and the corresponding connection of running-on end face of the measurer axle sleeve of end together, the axle body and the locating sleeve of measurer axle sleeve are in axial sliding connection, the other end of measurer axle sleeve is connected with tight locking catch melon, tight locking catch melon and tight corresponding being slidingly connected of plush copper of locking plush copper, one end of tight lock plush copper is connected by the inboard wall groove of spring with the measurer axle sleeve, and the other end of tightly locking plush copper is connected with the not end of screw rod.

Described locating sleeve is provided with dog screw, one side of the measuring contacts of the corresponding dial gauge of locating sleeve is the reference measurement end face, described dial gauge is connected with the measurer axle sleeve by supporting, attaching nut, lining and holding screw, the measuring contacts of dial gauge is corresponding with reference measurement end face on the locating sleeve, and locating sleeve is in axial sliding connection by sliding tray on screw and the measurer axle sleeve and measurer axle sleeve.

The shaft of described screw rod is provided with sliding recess and the corresponding connection of directional bolt on the measurer axle sleeve.

Described tight locking catch melon is that four or six of rotational symmetry setting grab melon, connects elastic ring on the tight locking catch melon melon body.

The utility model is owing to use dial gauge just can detect differential side gear gap measurer.This measurer is simple in structure, cost is low, economical and practical.Use this measurer, can measure the differential side gear gap, can reselect the axle shaft gear pad,, thereby reach the drawing requirement, guarantee product quality by increase or minimizing axle shaft gear spacer thickness to the gap is underproof.

Description of drawings

Fig. 1, the utility model are measured the status architecture synoptic diagram.

Among Fig. 1: setscrew nut 1, screw rod 2, measurer axle sleeve 3, attaching nut 4, lining 5, holding screw 6, supporting 7, dog screw 8, locating sleeve 9, tight locking catch melon 10, elastic ring 11, tightly lock plush copper 12, directional bolt 13, spring 14, dial gauge 15.

Embodiment

Embodiment 1: it comprises measurer axle sleeve 3, dial gauge 15 is installed on the measurer axle sleeve 3, the interior body wall of described measurer axle sleeve 3 and the shaft of screw rod 2 are in axial sliding connection, setscrew nut 1 is connected with an end spiral of screw rod 2, the screw socket end face of setscrew nut 1 and the corresponding connection of running-on end face of the measurer axle sleeve 3 of end together, the axle body of measurer axle sleeve 3 and locating sleeve 9 are in axial sliding connection, the other end of measurer axle sleeve 3 is connected with tight locking catch melon 10, tight locking catch melon 10 and tight corresponding being slidingly connected of plush copper of locking plush copper 12, one end of tight lock plush copper 12 is connected with the inboard wall groove of measurer axle sleeve 3 by spring 14, and the other end of tightly locking plush copper 12 is connected with the not end of screw rod 2 by its inboard wall groove.

Described locating sleeve 9 is provided with dog screw 8, one side of the measuring contacts of locating sleeve 9 corresponding dial gauges 15 is the reference measurement end face, described dial gauge 15 is connected with measurer axle sleeve 3 with holding screw 6 by supporting 7, attaching nut 4, lining 5, the measuring contacts of dial gauge 15 is corresponding with reference measurement end face on the locating sleeve 9, and locating sleeve 9 is in axial sliding connection by sliding tray on screw and the measurer axle sleeve 3 and measurer axle sleeve 3.

The shaft of described screw rod 2 is provided with the directional bolt 13 corresponding connections on sliding recess and the measurer axle sleeve 3.

Described tight locking catch melon 10 is that four or six of rotational symmetry setting grab melon, connects elastic ring 11 on the tight locking catch melon 10 melon bodies.

To detect all-cis rear axle differential side gear gap is example, the tight locking catch melon 10 of described measurer, one of inner chamber for taper hole, one for cylindrical hole, outside are right cylinders, be divided into 4 melons or 6 melons with line cutting again integral body processes after; Tight lock plush copper 12 major part cylindricals are that the cone microcephaly is a right cylinder, and inner chamber is a step through-hole, and cylindrical matches with measurer axle sleeve 3 endoporus.

Dial gauge 15 by support 7, attaching nut 4, lining 5 and holding screw 6 be fixed on the measurer axle sleeve 3; Locating sleeve 9 can move axially certain distance on measurer axle sleeve 3, but can not relatively rotate; When measuring differential side gear end play, measurer axle sleeve 3 and tight locking catch melon 10 are inserted in the axle shaft gear splined hole together, locating sleeve 9 end faces contact with the differential bearing end face; When just inserting the axle shaft gear splined hole, elastic body 10 hoops are in loose state on tight lock plush copper 12; Screw dog screw 8 make locating sleeve 9 on the differential carrier axle journal, with the differential mechanism relative fixed; Positioning of rotating nut 1, screw rod 2 is because directional bolt 13 plays the anti-rotation effect, can only move axially, screw rod 2 moves axially the tight lock of drive plush copper 12 and moves, thereby tight lock plush copper 12 taperings force tight locking catch melon 10 external diameters to increase and clamp axle shaft gear, be equivalent to axle shaft gear, tight lock plush copper 12, tight locking catch melon 10, measurer axle sleeve 3, setscrew nut 1 and dial gauge 15 form an integral body, move axially measurer axle sleeve 3, axle shaft gear and dial gauge 15 and then move, the ultimate range that measurer axle sleeve 3 is moved reflects by the variation between the reference measurement end face of dial gauge 15 and locating sleeve 9, promptly is differential side gear end play.Unclamp setscrew nut 1, tightly lock plush copper 12 and move in spring 14 effects, tight locking catch melon 10 is in loose state in elastic ring 11 effect reduced outside diameter; Unscrew dog screw 8, just can take out the utility model.The left and right two of differential mechanism axle shaft gear gap measuring method is the same.
