Abstract
It includes axis that the utility model discloses a kind of loading machine stabilized shaft gearbox gears with the connection structure of axis, adjustment gasket, combines roller bearing, gear, thrust roller bearing, oil cylinder and needle bearing；The axis is fixing piece；The oil cylinder is carried on axis by needle bearing；The gear is carried on axis by combining roller bearing, inner ring and the axis cooperation of the combination roller bearing, and roller is directly and bore cooperation, combination roller bearing carry out axial limiting by the adjustment gasket of left side and the thrust roller bearing of right side respectively；The right end of the thrust roller bearing is directly installed on the end step of oil cylinder.The utility model has the characteristics that structure and assembly are simple, production is low with maintenance cost, safe and reliable, solves the problems, such as that assembly efficiency existing in the prior art is low, difficulty is big and spacing shim not shock resistance is easy to damage and price is high, buying difficulty is big.
Description
Technical field
The utility model relates to loading machine stabilized shaft gearboxes, and in particular to the connection of loading machine stabilized shaft gearbox gear and axis
Structure.
Background technique
Currently, domestic loading machine stabilized shaft gearbox is generallyd use and secured a shaft on cabinet, gear is pacified using double-row roller
For carrying radial load on axis, gear both ends are limited using nonmetallic wear-resistant gasket, while bearing a part of axis
Xiang Li.The structure have the following deficiencies: 1., gear be directly installed on axis using double-row roller, assembly efficiency is low, and when assembly is easy
It falls off, assembly difficulty is big；2., gear both ends limited using nonmetallic wear-resistant gasket, though this gasket wearability is good, do not resist
Impact is easily damaged when assembling gimmick or components precision does not reach requirement, and this wear-resistant gasket is made of special material, state
It inside there is no substitution, price is high and buying is inconvenient.
Summary of the invention
The purpose of the utility model is to overcome drawbacks described above, a kind of structure is provided and assembly is simple, production and maintenance cost
The connection structure of low, safe and reliable loading machine stabilized shaft gearbox gear and axis, to solve assembly effect in the prior art
The problem that rate is low, difficulty is big and spacing shim not shock resistance is easy to damage and price is high, buying difficulty is big.
In order to achieve the above object, the connection structure of the utility model loading machine stabilized shaft gearbox gear and axis includes axis, adjusts
Whole gasket, combination roller bearing, gear, thrust roller bearing, oil cylinder and needle bearing；The axis is fixing piece；The oil cylinder
It is carried on axis by needle bearing；The gear by combine roller bearing be carried on axis, the combination roller bearing it is interior
Circle and axis cooperation, roller directly cooperate with bore, combine roller bearing respectively by the adjustment gasket and right end of left side
The thrust roller bearing in face carries out axial limiting；The right end of the thrust roller bearing is directly installed on the end step of oil cylinder
On.
Above-mentioned loading machine stabilized shaft gearbox gear substitutes original rolling by using roller bearing is combined with the connection structure of axis
Column is mounted directly mode, and gear face limit is changed to thrust roller bearing by original nonmetallic wear-resistant gasket, has following skill
Art feature and the utility model has the advantages that
1., gear carrying radial load is mounted on an axle using combined type roller bearing, assemble simple, high-efficient；
2., gear face limited using thrust roller bearing, structure is mature, and assembly is simple, is not easy because assembling reason
Failure is damaged, while price is lower, purchased without bottleneck.
Detailed description of the invention
Fig. 1 is the connection structure main cross-sectional schematic diagram of the utility model loading machine stabilized shaft gearbox gear and axis.
Appended drawing reference: axis 1, adjustment gasket 2, combination roller bearing 3, gear 4, thrust roller bearing 5, oil cylinder 6, needle roller axis
Hold 7.
Specific embodiment
With reference to the accompanying drawings and detailed description to the connection of the utility model loading machine stabilized shaft gearbox gear and axis
Structure is described in further detail.
Shown in Fig. 1, the connection structure of the utility model loading machine stabilized shaft gearbox gear and axis includes axis 1, adjustment gasket
2, roller bearing 3, gear 4, thrust roller bearing 5, oil cylinder 6 and needle bearing 7 are combined；The axis 1 is fixing piece；The oil cylinder
6 are carried on axis 1 by needle bearing 7；The gear 4 is carried on axis 1 by combining roller bearing 3, the combination roller axle
Hold 3 inner ring and axis 1 cooperate, roller directly and 4 inner hole of gear, combination roller bearing 3 respectively by the adjustment of left side
Gasket 2 and the thrust roller bearing of right side 5 carry out axial limiting；The right end of the thrust roller bearing 5 is directly installed on oil
On the end step of cylinder 6, to guarantee the service performance of the structure.
The gear 4 of the connection structure of above-mentioned loading machine stabilized shaft gearbox gear and axis is installed using combined type roller bearing 3
On axis 1, assemble simple, high-efficient；The end face of gear 4 is limited using thrust roller bearing 5 and adjustment gasket 2 simultaneously,
Structure is mature, and assembly is simple, is not easy to damage failure, while low cost because of assembly reason, buying becomes without bottleneck, final improve
Fast case reliability and assembly efficiency increase enterprise income.
