Description
Technical field
The utility model relates to a kind of balance suspension assembly preventing bearing inner ring from rotating.
Background technology
Existing balance suspension assembly generally comprises equalizing bar and two strut mounts, two strut mounts are fixed by welding in the two ends of equalizing bar, spring block is set on balance shaft by oscillating bearing, then by black nut, oscillating bearing is carried out axial location on balance shaft, because of matching requirements, for ease of adjusting the tolerance clearance of oscillating bearing, the oscillating bearing inner ring of black nut homonymy is free-running fit with coordinating of balance shaft, under the effect of heavy lift, when spring block rotates around balance shaft, the inner ring of oscillating bearing there will be rotation phenomenon, balance shaft is caused to wear and tear, impact balance outstanding assembly integral service life.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is that the prevented bearing inner ring providing a kind of structure simple, safe and reliable rotates, thus the balance suspension assembly preventing balance shaft from wearing and tearing.
For achieving the above object, the utility model is by the following technical solutions:
A kind of balance suspension assembly preventing bearing inner ring from rotating, comprise equalizing bar and two strut mounts, described two strut mounts are fixed by welding in the two ends of equalizing bar, on each strut mount, equal close-fitting is fixed with balance shaft, one end of balance shaft is provided with step, this step is stuck in a side of strut mount, the other end of balance shaft extends the another side of strut mount, described balance shaft is arranged with spring block, two spaced oscillating bearings are provided with between described spring block and balance shaft, the end thread that described balance shaft extends strut mount another side is connected with black nut, this black nut is for being fixed on balance shaft by oscillating bearing, described black nut and with its with side oscillating bearing inner ring on stop pin is installed.
Described black nut is provided with the first lock pin aperture.
The inner ring of described oscillating bearing is provided with the second lock pin aperture.
The second lock pin aperture that the inner ring of described oscillating bearing is arranged is at same circumferentially uniform 3 rounds that arrange, and often arranges 4.
Described stop pin diameter is φ 8mm, and stop pin is through modifier treatment, and quenching and tempering hardness is HRC38 ~ 45.
The utility model adopts above technical scheme, relative fixing is carried out by black nut with the inner ring of its homonymy oscillating bearing by stop pin, can effectively prevent oscillating bearing inner ring from rotating and balance shaft is worn and torn, thus improve the whole service life of balance suspension assembly, because the inner ring of oscillating bearing is provided with 3 rounds, often arrange 4, totally 12 the second lock pin aperture, after can ensureing that black nut is fastening and putting in place, lock pin aperture on black nut can communicate with the lock pin aperture on the inner ring of oscillating bearing, is convenient to the installation of stop pin.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is the configuration diagram of a kind of balance suspension assembly preventing bearing inner ring from rotating of the utility model;
Fig. 2 is the configuration diagram of black nut in the utility model;
Fig. 3 is the configuration diagram of oscillating bearing inner ring in the utility model.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 or Fig. 3, the utility model comprises equalizing bar 1 and two strut mounts 2, described two strut mounts 2 are fixed by welding in the two ends of equalizing bar 1, on each strut mount 2, equal close-fitting is fixed with balance shaft 3, one end of balance shaft 3 is provided with step 31, this step 31 is stuck in a side of strut mount 2, the other end of balance shaft 3 extends the another side of strut mount 2, described balance shaft 3 is arranged with spring block 4, two spaced oscillating bearings 5 are provided with between described spring block 4 and balance shaft 3, the end thread that described balance shaft 3 extends strut mount 2 another side is connected with black nut 6, this black nut 6 is for being fixed on balance shaft 3 by oscillating bearing 5, described black nut 6 and with the inner ring of the oscillating bearing 5 of its homonymy on stop pin 7 is installed, stop pin 7 diameter is φ 8, stop pin 7 is through modifier treatment, quenching and tempering hardness is HRC38 ~ 45.
Described black nut 6 being provided with two the first lock pin aperture 8, first lock pin aperture 8 is through hole, and the first lock pin aperture 8 diameter is φ 8mm, and hole width between centers is 135mm.
Circumferentially being laid with of the inner ring of the oscillating bearing 5 of described black nut 6 homonymy 3 ranked second lock pin aperture 9, and often row is 4 second lock pin aperture 9, second lock pin aperture 9 degree of depth is 10mm, and the second lock pin aperture 9 diameter is φ 8mm.
The first lock pin aperture 8 on black nut 6 installs a stop pin 7 with in the second lock pin aperture 9 on relative oscillating bearing 5 inner ring.
The utility model carries out relative fixing by stop pin 7 by black nut 6 with the inner ring of its homonymy oscillating bearing 5, effectively can prevent oscillating bearing 5 inner ring from rotating and balance shaft 3 is worn and torn, thus improve the whole service life of balance suspension assembly.
