Abstract
The utility model relates to an elastic device for making a rotation part to shift on a high speed axle freely, which belongs to the technical field of mechanical transmission. The elastic device is composed of a stopping block, a corrugated spring and a rotating jacket. Two elastic devices are arranged on both sides of the high speed rotating axle and fixedly connected with the high speed rotating axle by the thread of an inner hole of the rotating jacket. The interior of the rotating jacket is provided with the corrugated spring and the stopping block. The corrugated spring is arranged inside the stopping block and the middle of the rotating jacket, and the stopping block and the high-speed rotating axle keep slide fit. The device has the advantages of simple structure, stable motion, reliable work, long service life, etc.
Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, particularly a kind of elastic device that rotary component is moved freely on high speed shaft.
Background technique
On high-speed rotating shaft, because moving axially of high-speed rotary part causes the position of its supporting part to change, the first critical speed of axle is also changed, and then have influence on the variation of the deformation plance Support Position of axle.
The model utility content
The purpose of this utility model is in order to overcome the problem that prior art exists, a kind of elastic device that rotary component is moved freely on high speed shaft to be provided.
This elastic device is made up of block, ripple spring and rotary sleeve, described elastic device is arranged on the both sides of high-speed rotating shaft, and be connected and fixed by the screw thread and the high-speed rotating shaft of rotary sleeve endoporus, in the running shaft overcoat, ripple spring and block are housed, the ripple spring is arranged on the block inboard, and place the centre of rotary sleeve, block and high-speed rotating shaft are slidingly matched, the crest of ripple spring inserts in the corresponding groove of block, key on the block cylindrical is connected with keyway on the rotary sleeve, with this, transmits axial force by block.The utlity model has simple in structurely, make high-speed rotary part motion steadily, and can on high speed shaft, move freely reliable operation, advantages such as long service life.

Embodiment
As shown in the figure, a kind of elastic device is by block 1, rotary sleeve 2, ripple spring 3 is formed, two elastic devices are arranged on the both sides of high-speed rotating shaft, and the screw thread by rotary sleeve 2 endoporus is connected and fixed with axle, 2 li of rotary sleeves ripple spring 3 and block 1 are housed, ripple spring 3 is arranged on the inboard of block 1, and place the centre of rotary sleeve 2, ripple spring 3 is provided with the sinusoidal crest of four five equilibriums, have four five equilibrium corresponding recesses on the block 1, the crest of ripple spring 3 is inserted in the block corresponding recesses, guarantee that ripple spring 3 and axle do not have relative movement, two keys on block 1 cylindrical are connected with two keyways on the rotary sleeve 2, and slip within it, elastic device and high-speed rotating shaft are rotated synchronously, and block 1 is moved axially on high-speed rotating shaft, and play thrust, when the shaft orientation moving range of the relative axle of high-speed rotary part is 0-1mm, the thickness of ripple spring 3 is that 0.2-0.5mm is best, and its free state overall width is that 4-5mm is advisable.Because the expansion problem after 3 compressions of ripple spring, its external diameter increases along with the increase of decrement, it is stuck not to be rotated overcoat 2 after be compressed, by the internal diameter that calculates ripple spring 3 is Φ 23.5～23.6mm, in decrement is 0 o'clock, external diameter is Φ 31.5～Φ 31.6mm, when decrement reaches 0.5mm, its external diameter is Φ 31.95～Φ 31.95mm, the endoporus of rotary sleeve 2 is Φ 32～Φ 32.25mm, so be unlikely to cause in compression process ripple spring 3 stuck phenomenons to take place.
Claims (4)
1, a kind of elastic device that rotary component is moved freely on high speed shaft, by block, rotary sleeve, the ripple spring is formed, it is characterized in that in rotary sleeve, being equipped with ripple spring and block, the ripple spring is arranged on the block inboard, and places the centre of rotary sleeve, and block and high-speed rotating shaft are slidingly matched, the crest of ripple spring inserts in the corresponding groove of block, and the key on the block cylindrical is connected with keyway on the rotary sleeve.
2, elastic device as claimed in claim 1 is characterized in that described ripple spring has the sinusoidal crest of four five equilibriums.
3, elastic device as claimed in claim 1 is characterized in that described block side has the groove of four five equilibriums, and cylindrical has 2 keys.
4, elastic device as claimed in claim 1 is characterized in that described rotary sleeve has two keyways.
