Description
Technical field
The utility model belongs to measuring tool technical field more particularly to a kind of speed changer assembly is measured with bearing pre-fastening
Tool.
Background technology
The adjustment of bearing pre-fastening is the key link in speed changer assembly, and traditional method of adjustment is direct measurement assembly
Middle (center) bearing height and casing depth obtain gasket installation value by calculating difference.Not only measurement method is cumbersome, efficiency is low, and axis
It is unstable to hold height measurements, seriously affects adjustment quality.
Invention content
The utility model aim is to provide bearing pretightening force measuring tool, reach measurement method is quick, measure value stabilization can
It leans on, ensure to adjust the purpose of quality.
The utility model realizes that above-mentioned purpose adopts the technical scheme that：Bearing pretightening force measuring tool, mainly by mandril,
Fixing device and bearing pressing device composition, the fixing device is mounted on case of transmission, in the fixing device
Upper surface center is connected with mandril, and the bearing pressing device is located in fixing device, and bearing pressing device and fixing device
Coaxially, it is linked together by mandril.
Further, the mandril is screw-rod structure.
Further, the fixing device is mounted on bolt on case of transmission.
The utility model has the beneficial effects that：
Bearing height is measured using bearing pretightening force measuring tool when speed changer assembles, not only measurement method is convenient, fast,
And it ensure that bearing pre-fastening precision and reliability.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, mandril；2, fixing device；3, bearing pressing device.
Specific implementation mode
It is as follows to be described with reference to the accompanying drawings the utility model：
As shown in Figure 1：Bearing pretightening force measuring tool for assembling transmission described in the present embodiment is by mandril 1, fixed dress
2 and the composition of bearing pressing device 3 are set, the fixing device 2 is mounted on bolt on case of transmission, in the fixing device
2 upper surface center is connected with mandril 1, and the mandril 1 is screw-rod structure, and the bearing pressing device 3 is located at fixing device 2
Interior, bearing pressing device 3 and fixing device 2 are coaxial, are linked together by mandril 1, and drive its adjustment by mandril 1.
Bearing pretightening force measuring tool for assembling transmission application method：Fixing device is mounted on transmission case with bolt
On body, mandril 1 is tightened, measure at bearing pressing device 3 from after the bearing cap mounting surface to jackshaft of gear box casing outside bearing
The size of circle keeps bearing cap minimum to the gap of bearing.
