Abstract
A mandrel for a spinning machine or a yarn twister comprises a rotating axostylus supported in a bearing box of the mandrel by a mid-bearing and a vertical thrust bearing. The vertical thrust bearing comprises a vertical thrust bearing box cylinder arranged in a centering tube. The mid-bearing part of the centering tube is clipped in the bearing box of the mandrel, and the vertical thrust bearing part is supported movably in radial direction on the bearing box of the mandrel by a damping coil-spring. A twisted ring groove is arranged, so a flexible area is formed between the mid-bearing and the vertical thrust bearing of the centering tube. More than half part of the flexible area is extended to the damping coil-spring without any support.
Description
Technical field
The present invention relates to a kind of axle that is used for spinning machine or twisting machine, it comprises a rotary shaft, this axostylus axostyle relies on an intermediate bearing and a step bearing to be bearing in the bearing housing of axle, step bearing comprises a step bearing case tube that is arranged in the centring tube, centring tube is sandwiched in the bearing housing of axle at the intermediate bearing place, and can be supported on the spindle bearing case by the damping helical spring at the step bearing place with moving radially, because a spiral helicine annular groove is arranged, this centring tube has a flexible region between intermediate bearing and step bearing, this flexible region does not reach in the damping helical spring with partly having supporting.
Background technology
The prior art of this axle is the application 11 36 918 of and examination open in Germany.In the disclosure document, related to a kind of safety device that prevents that removable axle top accident from flying off.This document has been showed a kind of common embodiment in relevant diagram, but does not describe in detail, and according to this embodiment, it provides and has started mentioned the sort of centring tube, and this centring tube is owing to a spiral helicine annular groove thereby comprise a flexible region.This centring tube is bearing on the total length of damping helical spring usually, so flexible region is to place the outside, in other words, is positioned at damping helical spring top.And for above mentioned open source literature, among the embodiment that does not have to describe in detail that it is showed, this flexible region has not reached in the damping helical spring with partly having supporting.Be different from the elaboration of standard design for this embodiment, in open source literature, do not provide.
For above mentioned the sort of axle, its trend is littler diameter and shorter axostylus axostyle length.Thereby can realize higher running speed.Yet because the cause of toroidal helical groove, centring tube can not be tending towards littler diameter and keeps synchronously with axostylus axostyle aspect this above-mentioned.When jackshaft holds when dwindling because of axostylus axostyle shortens with the spacing of step bearing, centring tube needs more to go deep into damping helical spring zone inevitably together with its flexible region.Yet this flexible region should not be bearing on the damping helical spring, because otherwise the flexibility of flexible region inside will be lost.
Summary of the invention
Task of the present invention is specially for spindle shaft designs a kind of axle mentioned above, and compared with general spindle shaft at present, the littler length of its diameter is shorter, particularly at the diameter at intermediate bearing place less than existing standard size 6.8mm.
According to the present invention, reach nothing supporting flexible portion in the damping helical spring greater than half of total flexible region, finish this task thus.
According to the present invention, it provides a calculation criterion for axle above mentioned and that very likely showed by prior art by accident, and this criterion does not come into question in above-mentioned open source literature.Especially, when not having the subtotalled that does not stretch into damping helical spring zone in supporting ground and be approximately 2/3rds of flexible region and grow, produced a kind of axle that is bearing at the step bearing place on the damping helical spring.And shown that this is enough.The bending strength of centring tube does not weaken because of the damping helical spring.What be different from current standard is, centring tube be bearing in damping helical spring length about 1/3rd on.
These and other purpose of the present invention, feature and advantage can become clearer from following detailed description to embodiment.
Description of drawings
Accompanying drawing shows according to axle cutaway view of the present invention.
The specific embodiment
According to the present invention, the axle 1 that is arranged vertically and is designed to annular shaft comprises a spindle shaft that can be driven in rotation 2, and the step bearing 4 that above-mentioned spindle shaft 2 is made up of the intermediate bearing 3 of a roller bearing form and one two parts supports together.Intermediate bearing 3 and step bearing 4 all are arranged in the spindle bearing case 5 that is made from multiple components.
Step bearing 4 bears the thrust plate 12 of axial force by one and 11 in the step bearing case tube of a bearing radial force is formed.Step bearing case tube 11 is fixed on itself and is clipped in centring tube 13 in the bearing head 9 by interference fit 14.Centring tube 13 includes a spiral helicine groove 15, makes the flexibility of centring tube 13 reach the degree of expectation, so it can move radially at step bearing 4 places.
The gap that has an annular between the cylindrical form interior surface of sleeve 7,8 and the cylindrical outer surface of centring tube 13, and damping helical spring 16 just is contained in this gap in a kind of known mode.Damping helical spring 16 is arranged in the oil bath device by whole.Rely on two via holes 17,18 on the positioning pipe 13, holding the annular space of damping helical spring 16 and communicating with oil bath device in the step bearing 4.Centring tube 13 is bearing on the spindle bearing case 5 by damping helical spring 16.And the spacing ring 19 of damping helical spring 16 by the top supports.
Axle 1 is connected on axle bed 20 (only representing with chain-dotted line) with the axle of other many adjacency by a kind of known mode.Axle 1 has also disposed a driving flywheel (not shown), and all driving flywheels all can bring driving in the vertical upwardly extending continuous transmission of machine by one.
The present invention be more particularly directed to a kind of axle 1, less than current standard, or rather, diameter is less than 6.8mm at the diameter at intermediate bearing 3 places for its axostylus axostyle 2.Owing to dynamic (dynamical) reason, when the diameter that holds when jackshaft reduced, the bending strength of spindle shaft 2 should not be lowered, so the spacing of intermediate bearing 3 and step bearing 4 must be dwindled.Centring tube 13 mills out a helical groove 15 in 360 ° of scopes, make centring tube 13 have a softer flexible region B, and reached in the zone of damping helical spring 16.Not weakened for the effect that makes this flex region B, so the flexible region section B of centring tube 13 can not support by damped helical spring 16, so a subregion T of flexible region reaches in the damping helical spring 16.According to the present invention, this subregion T surpasses half of flexible region B.The subregion T that does not reach in the damping helical spring 16 preferably is approximately 2/3rds of flexible region B with having supporting.
Through showing that 13 of centring tubes are bearing in 1st/3rd of about damping helical spring 16 length, and are enough.Centring tube 13 mainly is exactly damped helical spring 16 supportings at step bearing 4 places, and the above and below of this position all has very long one section not to be supported.Though the contraction in length of spindle shaft 2, the bending strength of centring tube 13 is not weakened.
