Abstract
The invention discloses a kind of pivoting support of slide construction, belong to engineering machinery field.Which overcome traditional rolling structure pivoting support raceway fatiguability damage, the defect that service life is short, maintenance cost is high.It includes left housing, inner ring, right shell, and the left housing, inner ring, right shell are loop configuration, and the left housing is fixedly connected with right shell, and the outer rim of the inner side and inner ring of left housing and right shell is slidably connected.The present invention is applied to be used on land leveller back axle, and long lifespan, reliability are high, substantially increase product quality.
Description
Technical field
The invention belongs to a kind of engineering mechanical components, specifically, more particularly to a kind of pivoting support of slide construction.
Background technology
At present, domestic land leveller back axle, mostly using main transmission+hub reduction gear+balance box structure.After this land leveller
Bridge slowed down using main transmission increase turn round after transfer power to hub reduction gear through semiaxis, hub reduction gear further slow down increasing turn round by
Double strand chain wheel shaft by power be transferred to Chain conveyer in tandem-driving bogie, tandem-driving bogie slow down again increasing torsion realize three-level slow down.This three-level
Slowing-down structure transmission moment of torsion is big, it is possible to achieve the big power demand of low speed of land leveller work, is widely used.Due to land leveller complete machine
Heavier with back axle, hub reduction gear and tandem-driving bogie attachment structure bear larger turning torque, therefore hub reduction gear and tandem-driving bogie
The reliability of coupling part is particularly important.
Traditional land leveller rear axle wheel reductor decelerator and tandem-driving bogie coupling part has following two structure types：First, support
The bearing of copper sheathing+three (two taper roll bearings and a double-row bearing) structure, this structure existed in the presence of three bearings
Positioning is easily caused middle taper roll bearing and damaged；2nd, rolling revolving supporting structure.This structure avoids the excessively fixed of said structure
Position problem, but rolling revolving bearing contact areas is small, and contact stress is big；Pivoting support is moved back and forth along 15 °~20 ° pivot angles, rolling
Road fatiguability is damaged；Raceway machining accuracy is high, and, it is necessary to be heat-treated, manufacture difficulty is big, and cost is high.Change or maintenance double-row bearing with
And rolling structure pivoting support, maintenance time length, cost height, cause the operating efficiency of land leveller to reduce, production cost is raised, visitor
The economic loss at family is increased.
The content of the invention
It is existing to overcome it is an object of the present invention to provide a kind of reliability height, the pivoting support of the slide construction of use time length
With the presence of the high problem of poor reliability, maintenance cost of traditional land leveller rear axle wheel reductor decelerator and tandem-driving bogie attachment structure in technology
Defect.
The present invention is realized using following technical scheme：
A kind of pivoting support of slide construction, including left housing, inner ring, right shell, the left housing, inner ring, right shell are annular
Structure, the left housing is fixedly connected with right shell, and the outer rim of the inner side and inner ring of left housing and right shell is slidably connected.
Wear-resisting bushing is provided with the top of the inner ring outer rim between left housing.
Wear-resisting packing ring is housed between the inner ring outer rim both sides and left housing, right shell.
It is equipped with the pivoting support in forced filling oil cup, left housing and is provided with oil duct.
Sealing ring A is provided between the left housing and inner ring.
Sealing ring B is provided between the right shell and inner ring.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) pivoting support of slide construction effectively prevent the mistake orientation problem that the bearing arrangement of supporting copper sheathing+three is caused；
(2) the pivoting support contact area of slide construction is big, and contact stress is small and each several part is not required to heat treatment, pivoting support
Long lifespan.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, right shell 10 coordinates with tandem-driving bogie 1 in pivoting support 2 of the present invention, and it is bolted；Revolution branch
Inner ring 8 coordinates with hub reduction gear 3 in holding 2, and is bolted.
As shown in Figure 2 and Figure 3, a kind of pivoting support of slide construction, including left housing 4, inner ring 8, right shell 10, the left housing
4th, inner ring 8, right shell 10 are loop configuration, and the left housing 4 is fixedly connected with right shell 10, and left housing 4 and the inner ring of right shell 10
It is slidably connected with the outer rim of inner ring 8；Left housing 4 and right shell 10 are connected by screw 9.
Wear-resisting bushing 5 is provided with the top of the outer rim of inner ring 8 between left housing 4；The outer rim both sides of inner ring 8 and left housing 4,
Wear-resisting packing ring 6 is housed between right shell 10.
Sealing ring A7 is provided between the left housing 4 and inner ring 8, sealing ring A7 is used to prevent that grease oozes out in pivoting support 2
With it is dust-proof；Sealing ring B11 is provided between the right shell 10 and inner ring 8, sealing ring B11 is used to prevent the oil in tandem-driving bogie 1 from oozing out.
Oil duct is provided with as shown in figure 4, being equipped with pivoting support 2 in forced filling oil cup 12, left housing 4, is needed periodically to slide construction
Pivoting support 2 filling grease.
When land leveller works, inner ring 8 and hub reduction gear 3 are bolted on together, left housing 4, right shell 10 and balance
Case 1 is bolted on together, can be relatively rotated between inner ring 8 and left housing 4, right shell 10, bushing 5 and packing ring therebetween
6 have stronger wearability, and pivoting support 2 bears most complete machine and the weight of bridge, and inner ring 8, the bushing of pivoting support 2
5th, left housing 4, right shell 10 have the ability of carrying heavy duty and lasted a long time.The present invention applies the service life on land leveller back axle
Long, reliability is high, overcomes that traditional rolling structure pivoting support raceway fatiguability is damaged, service life is short, maintenance cost is high
Shortcoming, substantially increases product quality.
