Description
Technical field
The utility model belongs to a kind of textile machine parts, particularly relates to a kind of cladding spindle through improved vibrationproof well.
Background technology
Cladding spindle is a kind of textile machine parts, is mainly used in coating machine, and the spindle blade of spindle is hollow, and its effect is, the heart yearn of covering filament is by the through hole of spindle blade during work, and spindle blade rotates and makes yarn on heart yearn, thereby forms covering filament.The existing spindle that generally uses is that bearing is installed on the spindle blade, and bearing is provided with bolster outward, and bolster is provided with shock-absorbing sleeve outward, but this spindle bearing capacity is poor, and stability is bad, and noise increases in use for some time.Chinese patent 99229270.0 discloses a kind of cladding spindle, this utility model patent improves the spindle support of spindle, between the metal (upper of spindle blade and spindle support, the rubber shock-absorbing sleeve up and down that directly is enclosed within outside the bearing is set respectively, at the cover plate of the upper end of spindle support adapter sleeve outside spindle blade, in the hope of improving bearing capacity and stability.In this utility model patent, last rubber shock-absorbing sleeve is to be arranged to up-small and down-big truncated cone-shaped, and ingot lid downside be provided with the corresponding diameter of this truncated cone-shaped be up-small and down-big loop configuration, will go up rubber shock-absorbing sleeve and compress and make it stable by the ingot lid being screwed in spindle support.The structure relative complex of this cladding spindle, thereby manufacturing cost improves.Chinese patent 200520101124.5 discloses a kind of noiseless cladding spindle, and it is can fill with lubricating oil in spindle support, and metal (upper can be immersed among the lubricating oil.This utility model patent has overcome prior art because the high speed rotating of spindle blade causes bearing wear, thereby causes the defective that service life is short, noise is big.Yet this noiseless cladding spindle exists complex structure, problem that manufacturing cost is high equally.
The utility model content
The utility model has proposed a kind of cladding spindle for solving the deficiency that above-mentioned prior art exists, and this cladding spindle reasonable in design, manufacturing cost reduce relatively, and has stability preferably, long-play under the environment of high speed rotating.
The technical solution of the utility model is:
A kind of cladding spindle comprises spindle blade, spindle support, ingot lid, upper bearing (metal), lower bearing, ingot pulley, goes up coupling sleeve, lower link cover, spring, tightly is placed in the last rubber ring and the following rubber ring in upper bearing (metal) and the lower bearing outside, at the through hole that is axially arranged with of described spindle support; Bearing is installed on described through hole top and last rubber ring place reaches with the upper part, and the diameter at bottom installation lower bearing and following rubber ring place and following position is bigger than the middle part.
The hole wall that bearing and last rubber ring position are installed in described through hole top is provided with the groove that is used to settle rubber ring; Perhaps described through hole top is installed the hole wall at bearing and last rubber ring position and is arranged to the surface of revolution of an oblique straight line around central shaft, and the diameter of described through hole at this position increases from bottom to top gradually.Correspondingly, the described rubber ring of going up is made as O shape rubber ring; The perhaps described rubber ring of going up is made as the truncated cone-shaped rubber ring that is axially arranged with through hole and is provided with groove in hole wall.
About institute's fortune lower bearing, be equipped with the end face rubber ring on the outer ring of both ends of the surface; Described end face rubber ring places the disc bayonet socket.
In the utility model, two bearings can be by rubber ring is stable well up and down up and down.The design of last rubber ring position hole wall makes rubber ring can be stabilized in this position and the effect that needn't rely on ingot lid to compress, upper bearing (metal) under the effect of last rubber ring, the energy even running.Therefore, saved the circulus of ingot lid downside in the utility model, the ingot lid only need possess dust reduction capability.On the outer ring of both ends of the surface the end face rubber ring is set about the lower bearing, lower bearing not only is subjected to down the effect of rubber ring, and under the effect of end face rubber ring, thereby its operation is more steady.
In the utility model, install bearing and last rubber ring place reaches with the upper part on spindle support axially extending bore top, and the diameter at bottom installation lower bearing and following rubber ring place and following position is bigger than the middle part, form the protruding seat of disc and the disc convex shoulder of broad respectively, thereby saved under the last rubber ring and pad or elastic scheibe on the following rubber ring.
The utility model is reasonable in design, and structure is simplified, and manufacturing cost reduces, and has improved resistance to shock to a great extent, and making it can long-time steady operation under the environment of high speed rotating.

Fig. 1 is a kind of embodiment schematic diagram of the utility model.
Fig. 2 is the another kind of embodiment schematic diagram of the utility model.
The specific embodiment
As shown in Figure 1, comprise spindle blade 2, spindle support 8, ingot lid 6, upper bearing (metal) 10, lower bearing 13, ingot pulley 5, last coupling sleeve 1, lower link cover 3, spring 4, last rubber ring 7 and following rubber ring 14.Spindle support 8 be axially arranged with through hole, bearing 10 is installed on this through hole top and last rubber ring 7 places reach with the upper part, and the diameter at bottom installation lower bearing 13 and following rubber ring 14 places and following position is bigger than the middle part, form the protruding seat of disc and the disc convex shoulder of broad respectively, and on the hole wall of installing bearing 10 and last rubber ring 7 positions, be provided with the groove 9 that is used to settle rubber ring 7; Last rubber ring 7 is an O shape rubber ring.On the outer ring of lower bearing both ends of the surface about in the of 13, be equipped with end face rubber ring 12; End face rubber ring 12 places disc bayonet socket 11.
