Technical field
The invention belongs to test tool testing fields, specifically a kind of main reducing gear driving and driven bevel gear back lash
Measuring device and measuring method.
Background technology
Since either offroad vehicle is mostly front-engine rear-drive or 4 wheel driven to current limousine, car will ensure the comfortable of vehicle
Property, offroad vehicle will ensure also to ensure the comfort of vehicle outside cross-country ability, therefore for the engagement of the transmission gear in rear axle
Required precision is relatively high, if gear backlash is larger, will generate larger noise in entire transmission process, while by
Percussion between gear can cause gear to be damaged, to make the lost of life of gear;If gear backlash compared with
It is small, gear can be made unstable in transmission process, the heat generated in operational process is excessive, causes gear ablation etc. occur bad
The generation of operating mode, therefore rational gear backlash is just most important for entire transmission system.
When dividing shell-type main gearbox assembly to measure gear backlash, due to this kind of structure type and common main deceleration
Device assembly structure is variant, and when measuring principal and subordinate bevel gear back lash, general test method is traditional main gearbox assembly
The tooth top position of driven wheel of differential big end, fixed input flange, clockwise or inverse time are directly vertically acted against with dial gauge contact
Needle rotates driven wheel of differential, when it is front and back be in contact respectively at drive bevel gear when, recorded in front and back rotation process from dial gauge,
The reading of dial gauge, it is considered that the reading is the back lash of driving and driven bevel gear static state, divides shell-type main gearbox assembly
Due to it is entire actively from bevel gear inside housings, directly can not measure driving and driven bevel gear with measuring instrumentss from outside
Back lash, it is therefore desirable to which clearance test is engaged by a set of tooling auxiliary tool.
By patent searching file, do not find that the tooling that the main gearbox assembly gear backlash of the type measures is auxiliary
Tool and methods are introduced in a kind of seal chamber internal gear back lash measurement method of Patent No. CN2001036107.6
Test method is not suitable for this kind of main gearbox assembly gear backlash and measures.
