Abstract
The utility model discloses a kind of gears meshing normal gap and detect frock, relate to machinery manufacturing technology field; Comprise the base plate that two pieces of back up pads be arranged in parallel and a piece are connected to two pieces of described back up pad bottoms, be provided with in coaxial the first groove of arranging and the second groove two pieces of described support plate top surface.Compared with prior art, the utility model can solve the measurement of existing gears meshing normal gap not only wastes time and energy but also measure inaccurate problem.
Description
Technical field
The utility model relates to technological equipment manufacturing technology field, especially a kind of frock for measuring normal gap when mated gear engages.
Background technology
When designing and developing a kind of new product, the size of the normal gap (back lash) wherein after mated gear engagement or span often have influence on the performance of product, at present, the measurement of paired meshing gear normal gap, general employing is measured the method for the thickness of galvanized wire again or is adopted the method for clearance gauge filling backlash to measure after galvanized wire being put between cog occlusion, these two kinds of methods not only waste time and energy but also measure inaccurate; Another kind method adopts three-coordinates measuring machine to measure, but this method needs to drop into larger fund, and measure more time-consuming, and cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of gears meshing normal gap and detects frock, and the measurement that it can solve existing gears meshing normal gap had not only been wasted time and energy but also inaccurate problem.
In order to solve the problem, the technical solution adopted in the utility model is: this gears meshing normal gap detects frock and comprises the base plate that two pieces of back up pads be arranged in parallel and a piece are connected to two pieces of described back up pad bottoms, is provided with in coaxial the first groove of arranging and the second groove two pieces of described support plate top surface.
In above technical scheme, further scheme can be: described first groove and described second groove are the semi-circular recesses be set in parallel.
Further: described first groove and described first groove are the V-type groove be set in parallel.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect: 1, simple, the low cost of manufacture of the utility model structure; 2, the utility model is for detecting the normal direction back lash of mated gear, easy to operate, measures accurately.

Fig. 1 is the front view of the utility model embodiment 1.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the detection schematic diagram of a pair gears meshing normal gap.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment 1:
Gears meshing normal gap as shown in Figure 1 and 2 detects frock, comprise two pieces of back up pads be arranged in parallel 2, one piece of base plate 4 is had at two pieces of back up pad 2 lower weld, the bottom surface of base plate 4 is concordant with the bottom surface of two pieces of back up pads 2, have the first groove 1 and the second groove 3 that have in the first groove 1 and the second groove 3, two pieces of back up pads 2 at the end face of two pieces of back up pads 2 are coaxial setting; First groove 1 of the present embodiment and the second groove 3 are the semi-circular recesses be set in parallel, namely the axial line of the first groove 1 and the second groove 3 is parallel to each other, first groove 1 and the second groove 3 are semi-circular recesses, the spacing of the axial line of the first groove 1 and the second groove 3 equals the reference radius sum of gear to be measured, and their axial line is parallel to each other and mutually vertical with back up pad.
During work, A, the first gear 5 of a pair gear to be detected and the second gear 6 are set on the first gear measurement mandrel 7 and the second gear measurement mandrel 8; B, the first gear measurement mandrel 7 and the second gear measurement mandrel 8 to be placed in the first groove 1 and the second groove 3 respectively, to use the first gear 5 and the second gear 6 to be in engagement; C, the second gear measurement mandrel 8 to be fixed, and the measurement contact measuring dial gauge 9 is touched the non-mesh tooth face of the first gear 5; D, rotate the first gear measurement mandrel 7 lightly, make the flank of tooth of the first gear 5 encounter the flank of tooth of the second gear 6, measure dial gauge 9 and obtain reading one; Rotate the first gear measurement mandrel 7 more lightly, the flank of tooth of the first gear 5 is made to encounter another flank of tooth of the second gear 6, measure dial gauge 9 and obtain reading two, reading one and reading two are subtracted each other the normal gap numerical value namely obtaining the first gear 5 and the second gear 6, as shown in Figure 3.
Embodiment 2:
First groove 1 and the second groove 3 are the V-type groove be set in parallel, and other features are identical with embodiment 1.
Claims (3)
1. a gears meshing normal gap detects frock, it is characterized in that: comprise the base plate (4) that two pieces of back up pads be arranged in parallel (2) and a piece are connected to two pieces of described back up pad (2) bottoms, be provided with in coaxial the first groove (1) of arranging and the second groove (3) at two pieces of described back up pad (2) end faces.
2. gears meshing normal gap according to claim 1 detects frock, it is characterized in that: described first groove (1) and described second groove (3) semi-circular recesses for being set in parallel.
3. gears meshing normal gap according to claim 1 detects frock, it is characterized in that: described first groove (1) and the V-type groove of described second groove (3) for being set in parallel.
