Abstract
The invention relates to a shaft, in particular to a shear shaft structure. The structure comprises a transmission shaft (1), a product main shaft (2) and sealing rings (3), wherein the transmission shaft (1) is connected with the product main shaft (2) through a spline; and the sealing rings (3) are arranged at joints of the transmission shaft (1) and the product main shaft (2). As the sealing rings (3) are arranged at the joints of the transmission shaft (1) and the product main shaft (2), when the transmission shaft drives the product main shaft to rotate, the sealing rings (3) can achieve a sealing effect on lubricating grease on the spline for connecting the transmission shaft (1) with the product main shaft (2); and meanwhile, the elastic action of the sealing rings (3) can substantially attenuate vibration caused by the transmission shaft, so that the service life of a product bearing is prolonged.
Description
Technical field
The present invention relates to a kind of axle, particularly to a kind of shearing axle construction.
Background technology
For rotating machinery, in prior art, power transmission shaft and product main shaft directly carry out rigidity and connect
Connect.This structure, it is impossible to effectively slow down the oscillating load of drive system, causes drive system
Vibration directly passes to product by power transmission shaft, so that product bearing is increased because of stress, leads to lose too early
Effect.
Content of the invention
Present invention solves the technical problem that being：One kind is provided can effectively to slow down drive system vibration,
Improve the axle construction of life of product.
The technical scheme is that：Described structure includes power transmission shaft 1, product main shaft 2 and
Sealing ring 3, power transmission shaft 1 and product main shaft 2 pass through spline connection, power transmission shaft 1 and product master
The junction of axle 2 is provided with sealing ring 3.
As one kind improvement of the technical program, the middle part of power transmission shaft 1 is machined with protection end face.
As one kind improvement of the technical program, the protection end face of power transmission shaft 1 is internal to be tied for hollow
Structure.
Beneficial effects of the present invention are：Because the technical program is in power transmission shaft 1 and product main shaft 2
Junction be provided with sealing ring 3.When power transmission shaft drives the rotation of product main shaft, sealing ring 3 is
The grease being connected between power transmission shaft 1 and product main shaft 2 at spline can be sealed,
The elastic reaction of sealing ring 3 can significantly slow down the vibration that power transmission shaft brings simultaneously, improves product
Bearing life.
Brief description
Fig. 1 is the structural representation of the present invention
In figure：1 is power transmission shaft, and 2 is product main shaft, and 3 is sealing ring.
Specific embodiment
Below in conjunction with the accompanying drawings the technical program is described in further details.
As shown in figure 1, power transmission shaft 1, product main shaft 2 and sealing ring 3, power transmission shaft 1 and product
Product main shaft 2 passes through spline connection, and the junction of power transmission shaft 1 and product main shaft 2 is provided with sealing
Circle 3.The maximum feature of this technical scheme is, fluted on power transmission shaft 1, peace in groove
Equipped with sealing ring 3.This groove is located at the junction of power transmission shaft 1 and product main shaft 2.Power transmission shaft
When driving the rotation of product main shaft, sealing ring 3 i.e. can be between power transmission shaft 1 and product main shaft 2
Connect the grease at spline to seal, the elastic reaction of sealing ring 3 can be significantly simultaneously
Slow down the vibration that power transmission shaft brings, improve product bearing life.
In addition, being machined with protection end face at the middle part of power transmission shaft 1.I.e. at the middle part of power transmission shaft 1
It is machined with the part that diameter is less than two ends diameter.This structure ensure that when product occurs clamping stagnation,
Only power transmission shaft 1 ruptures.Avoid the injury to product main shaft 2 during product clamping stagnation, fall
Low maintenance cost.
During in order to product rotation clamping stagnation is effectively ensured, power transmission shaft 1 is only allowed to rupture, in power transmission shaft 1
Mid diameter be less than two ends diameter position machined inner chamber.The size of this inner chamber can basis
The intensity requirement of axle and shearing moment require to be designed.
Claims (3)
1. a kind of axle construction, it is characterized by：Described structure includes power transmission shaft (1), product main shaft (2) and sealing ring (3), power transmission shaft (1) and product main shaft (2) pass through spline connection, and the junction of power transmission shaft (1) and product main shaft (2) is provided with sealing ring (3).
2. a kind of axle construction according to claim 1, it is characterized by：The middle part of power transmission shaft (1) is machined with protection end face.
