Description
Technical field
The utility model is related to a kind of noise of rotating shaft spline connection transmission to eliminate structure.
Background technology
It is mechanically operated common structure that rotating shaft is driven by spline connection, and spline connection is usually female splined shaft and is inserted in outward
Splined shaft, internal spline engages transmission rotation torque with external splines, so as to realize machine driving.But due to female splined shaft and outer flower
Sideshake can be formed in the flank of tooth after the assembling of key axle, while torque ripple can be produced when rotating shaft runs at high speed, so as to cause inside and outside flower
There is relative movement in key teeth face, causes tooth surface abrasion, and flank of tooth knock, reduces the service life of spline, and equipment
Running noises increase, and the normal operation of equipment is influenceed when serious.Wherein torque ripple mainly due to spline cogging torque it is uneven,
The concentricity of motor electromagnetic torque ripple, motor three-phase current unbalance and axle is bad etc., and factor is produced.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of noise of rotating shaft spline connection transmission and eliminates structure,
This structure overcomes the defect of conventional spline connection transmission, reduces spline tooth surface abrasion, effectively reduces equipment running noises, extension
Spline service life, it is ensured that the normal operation of equipment.
In order to solve the above technical problems, the noise of the utility model rotating shaft spline connection transmission eliminates structure includes internal spline
Axle and male splined shaft, the female splined shaft is inserted in the male splined shaft and internal spline is engaged with external splines, and this structure also includes
Resilience gear ring, the resilience gear ring is inserted in the shaft end of the male splined shaft and is engaged with the internal spline of the female splined shaft.
Further, each tooth of the resilience gear ring is provided with cavity above wheel rim.
Further, this structure also includes packing ring and nut, and the shaft end of the male splined shaft is provided with external screw thread, the gasket sleeve
Enter the shaft end of the male splined shaft, the nut is twisted the external screw thread in the male splined shaft shaft end and fastens the Elastic Teeth
Circle.
Further, this structure also includes O-ring seal, and the O-ring seal is located at the female splined shaft and male splined shaft
Interface between.
Above-mentioned technical proposal, i.e. this knot are employed because the noise of the utility model rotating shaft spline connection transmission eliminates structure
Structure includes female splined shaft and male splined shaft, and the female splined shaft is inserted in the male splined shaft and internal spline is engaged with external splines,
This structure also include resilience gear ring, the resilience gear ring be inserted in the shaft end of the male splined shaft and with the female splined shaft in
Spline engagement.This structure overcomes the defect of conventional spline connection transmission, reduces spline tooth surface abrasion, effectively reduces equipment operation
Noise, extends spline service life, it is ensured that the normal operation of equipment.
Brief description of the drawings
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings：
Fig. 1 is that the noise of the utility model rotating shaft spline connection transmission eliminates structural representation；
Fig. 2 is the part explosive view of this structure；
Fig. 3 is the A-A direction views of Fig. 1；
Fig. 4 is the B-B direction view of Fig. 1；
Fig. 5 is resilience gear ring schematic diagram in this structure.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the noise of the utility model rotating shaft spline connection transmission eliminates structure to embodiment
Including female splined shaft 1 and male splined shaft 2, the female splined shaft 1 is inserted in the male splined shaft 2 and internal spline is nibbled with external splines
Close, this structure also include resilience gear ring 3, the resilience gear ring 3 be inserted in the shaft end of the male splined shaft 2 and with the internal spline
The internal spline engagement of axle 1.
As shown in Figure 5, it is preferred that each tooth 31 of the resilience gear ring 3 is provided with cavity 32 above wheel rim.Cavity can make bullet
Property gear ring obtains elastic deformation when being engaged with the internal spline of female splined shaft, plays a part of buffering.
Preferably, this structure also includes packing ring 4 and nut 5, and the shaft end of the male splined shaft 2 is provided with external screw thread, the pad
Circle 4 is inserted in the shaft end of the male splined shaft 2, and the nut 5 is twisted the external screw thread in the shaft end of the male splined shaft 2 and fastened described
Resilience gear ring 3.
Preferably, this structure also includes O-ring seal 6, and the O-ring seal 6 is located at the female splined shaft 1 and external splines
Between the interface of axle 2.
In this structure, when by motor-driven rotating shaft in anxious accelerator, the impulsive force of interior external splines is acted on first
Resilience gear ring, forces resilience gear ring to deform, and in eliminating after the sideshake of external splines, inside and outside spline engagement realizes power transmission, this
When have part impulsive force absorbed by resilience gear ring, so as to reduce the stress of spline, it is to avoid interior external spline teeth face is clashed into, extension makes
With the life-span, improve equipment running noises；Simultaneously in rotating shaft normal operation, because torque ripple makes inside and outside spline fitted table
When face produces relative displacement, fretting wear, the displacement can also be absorbed by resilience gear ring, equally played and avoided abrasion, drop
Low noise and the effect for increasing the service life.
Resilience gear ring can be made using metal or working of plastics in this structure, and it has good rigidity and toughness, Neng Goucheng
By certain impact and deformation, to play the cushioning effect of inside and outside spline engagement.
This structure installs resilience gear ring additional by between interior male splined shaft, can effectively reduce noise, reduces spline wear,
Extension spline service life, and simple structure, it is convenient to realize, works well.
