Abstract
The utility model discloses a kind of one axis intermediate supports test mechanism of speed changer, the one axis intermediate supports test mechanism of speed changer includes bearing mounting base, bearing cover, wherein：The bearing mounting base is circumferentially distributed through-hole, is equipped with the first seam allowance close to the through hole, first seam allowance is circumferentially distributed threaded hole, and center is equipped with central through hole；The bearing cover is circumferentially evenly distributed with heavy mouth, and the threaded hole of the heavy mouth and bearing mounting base is fixed by screw-driving, and the second seam allowance in central through hole can be simultaneously embedded with central through hole size fit by being equipped at the heavy mouth.The structure design of the utility model is reasonable, compact, upgrading is transformed on the basis of existing test-bed, cost is saved, pass through effective cooperation of mechanical structure, under the premise of fully considering experiment, the support of an axis is used as by bearing, during experiment, the significant vibrations for reducing an axis, make experiment rationally effectively complete.
Description
Technical field
The utility model is related to a kind of one axis intermediate supports testing machines of speed changer for speed-changer synchronizer life test
Structure.
Background technology
With the continuous development of auto industry, automotive transmission technology is also increasingly updating.For new work transmission knot
For structure, when carrying out speed-changer synchronizer life test to it on existing test-bed, input shaft rotating speed vibrations are larger, influence
The normal examination in speed-changer synchronizer service life.
Invention content
The purpose of this utility model is that solve the problems, such as that input shaft vibrations are larger during transmission test, provide a kind of knot
Structure reasonable design, safely and effectively one axis intermediate supports test mechanism of speed changer.
The purpose of this utility model is achieved through the following technical solutions：
A kind of one axis intermediate supports test mechanism of speed changer, including bearing mounting base, bearing cover, wherein：
The bearing mounting base is circumferentially distributed through-hole, and the first seam allowance, first seam allowance are equipped with close to the through hole
Circumferentially distributed to have threaded hole, center is equipped with central through hole；
The bearing cover is circumferentially evenly distributed with heavy mouth, and the threaded hole of the heavy mouth and bearing mounting base is twisted by screw
It fastens, the second seam allowance in central through hole can be simultaneously embedded with central through hole size fit by being equipped at the heavy mouth.
The utility model has the following advantages：
The structure design of the utility model is reasonable, compact, and upgrading is transformed on the basis of existing test-bed, saves
Cost by effective cooperation of mechanical structure, under the premise of fully considering experiment, the support of an axis is used as by bearing, is being tried
During testing, the vibrations of an axis are significantly reduced, experiment is made rationally effectively to complete.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of bearing mounting base；
Fig. 3 is the sectional view of bearing mounting base；
Fig. 4 is the structure diagram of bearing cover；
Fig. 5 is the sectional view of bearing cover.
Specific embodiment
The technical solution of the utility model is further described below in conjunction with the accompanying drawings, however, it is not limited to this, every
Technical solutions of the utility model are modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of protection of the utility model.
As shown in Figs. 1-5, one axis intermediate supports test mechanism of speed changer provided by the utility model include bearing mounting base,
Bearing cover, wherein：
The bearing mounting base is circumferentially uniformly distributed there are four through-hole 1, and mounting base seam allowance 4, installation are equipped at through-hole 1
Seat seam allowance 4 is circumferential to be uniformly distributed there are four threaded hole 2, and 4 center of mounting base seam allowance is equipped with central through hole 3；
The bearing cover is circumferentially uniformly distributed that there are four heavy mouth 5, four institutes of four heavy mouths 5 and bearing mounting base
It states threaded hole 2 to fix by screw-driving, being equipped at the heavy mouth 5 can simultaneously be embedded in 3 size fit of central through hole
Cover board seam allowance 6 in heart through-hole 3.
In the utility model, through-hole 1 and the testing stand rebound through-hole of bearing mounting base tighten fixation by bolt, and pacify
It fills seat seam allowance 4 with testing stand rebound to coordinate, ensures the concentricity of installation, bearing cover sinks the screw thread of mouth 5 and bearing mounting base
Hole 2 is fixed by screw-driving, is reached compression axis and is made use, the central through hole 3 of bearing mounting base places bearing, one axis of speed changer
Bearing is inserted into, finally reaches the vibrations purpose of an axis during reduction transmission test.
