Description
Technical field
The utility model belongs to technical field of engineering machinery, and in particular to a kind of pivoting support component and land leveller.
Background technique
Currently, the land leveller rear axle produced both at home and abroad is mainly made of rear axle ontology and left-right balance box assembly, rear axle sheet
It is provided with main reducing gear in vivo, rear axle ontology is bolted on vehicle frame, to guarantee the smooth precision of land leveller not by operation
Face is uneven the influence of operating condition, and left-right balance case can be realized relative to rear axle ontology and be swung up and down.
In existing structure, opposite swing mainly is realized using following two connection type between tandem-driving bogie and rear axle ontology:
First is that using sliding bearing (copper sheathing or composite-material abrasive set), it is real using copper sheathing between tandem-driving bogie and rear axle ontology
It is now opposite to swing, it is had the following disadvantages using copper sheathing structure；1) after the abrasion of existing copper sheathing, semiaxis force-bearing situation is poor, causes
Between bearing life substantially shorten；2) copper sheathing maintenance frequency is higher, time-consuming and laborious；3) copper sheathing is vulnerable part, and service life is short, need to determine
Phase replacement, use cost are high.
Second is that rolling bearing structure is used, as shown in Figure 1, realizing phase using rolling bearing between tandem-driving bogie and rear axle ontology
To swing, pivoting support outer ring 7 is bolted with tandem-driving bogie, is sealed by outside O-ring 1, pivoting support inner ring 2 and wheel side
Reducing gearbox is bolted, and is sealed by inside O-ring 3, and pivoting support inner ring 2 and outer ring 7 are sealed by outside framework oil seal 4,
Outside framework oil seal 4 is fixed by sunk screw 5 and flange 6.Although the pivoting support of the structure meets tandem-driving bogie swing
Characteristic, it is not easy to wear, it seals more reliable.But the outside framework oil seal structure is fixed by flange, need to use a certain number of bolts
If flange is fixed on pivoting support inner ring by sunk screw, mounting structure is complicated.Meanwhile outside framework oil seal structure is positioned only at back
The side for turning bearing can not seal for the other side of pivoting support, and in actual use, pivoting support needs
Grease up is wanted, if grease adding is excessive, causes lubricating grease to overflow from pivoting support far from the side of outside framework oil seal, simultaneously
Also it is easy absorption dust, leads to Fast Wearing between pivoting support inner ring and pivoting support outer ring.
Therefore, the structure of pivoting support how is improved, to simplify structure, sealing performance is improved, is still art technology
Personnel's technical problem urgently to be resolved.
