Abstract
The utility model relates to a middle roller driving device of a ring throstle for a textile industry. The utility model comprises a middle roller head section (1), a middle roller drive gear (2) and a middle roller slide seat (3), wherein the middle roller head section is axially and radially supported by the middle roller slide seats (3) which are fixed on bottom seats of slide seats of lathe heads of the throstle; the middle roller slide seats (3) are arranged at both sides of the middle roller drive gear (2); the top parts of the slide seats (3) are fixed into a whole; radial support at both sides uses needle bearings. Thus, the influence for the radial bounce of the head section middle roller caused by the radial acting force of the middle roller drive gear is eliminated and the generation of head section drafting mechanical waves is eliminated. The utility model has the advantages of drafting mechanical wave elimination of the original head section, simple mechanism and easy reformation of original machine types.
Description
Technical field
The utility model relates to the middle roller transmission device of ring throstle in the textile industry.
Background technology
The middle roller transmission device of ring throstle is the critical piece of fine spining machine transmission device, plays an important role in the yarn drafting process.
Be the middle roller transmission device of existing fine spining machine shown in the accompanying drawing 2, it carries out radial support by the middle roller slide to the middle roller head section (1) in middle roller travelling gear (2) left side, is the supporting of side cantilever formula.When the gear drive middle roller, gear drive power upwards is directly delivered on the first section drafting unit, can cause middle roller to beat, and is easy to generate the yarn mechanical wave in the yarn drafting process, and then has influence on the yarn quality of spun yarn prow section drawing-off.
Summary of the invention
In order to overcome above weak point, main purpose of the present utility model aims to provide a kind of new construction middle roller transmission device, to eliminate gear drive power to the influence of first section drafting unit and the mechanical wave of yarn.
The technical problems to be solved in the utility model is: in fine spining machine geared head small space, by changing the structure of existing middle roller transmission device, improve the stressing conditions of middle roller head section, thereby eliminate the middle roller head section circular runout that gear drive caused, convenient simultaneously repacking.
The technical solution adopted in the utility model is: design one simultaneously to middle roller travelling gear both sides carry out radial support the middle roller slide.Described middle roller slide body is a supporting that is positioned at middle roller travelling gear both sides, and two radial supports adopt needle bearing, are the rigidity slide that is connected as a body at its top, and its slide left bottom structure is identical with existing middle roller slide polycrystalline substance.When the gear drive middle roller, gear drive power has been avoided the defective of former side cantilever formula supporting by the radially supporting simultaneously of middle roller slide both sides, has eliminated gear drive power the jumping effect of first section drafting unit and the mechanical wave of yarn are produced.
Effect of the present utility model is: can effectively eliminate since radial load that gear drive produced to the influence of middle roller head section, and a part of structure that only need change existing apparatus can realize, and is simple in structure, easy for installation.

The specific embodiment
The utility model improves on the basis of adopting existing middle roller slide base and middle roller travelling gear (2).Middle roller slide (3) baseplane, the left side links to each other with fine spining machine geared head slide base by bolt, and then middle roller head section (1) both sides that are positioned at middle roller travelling gear (2) both sides are carried out radial support simultaneously.
Claims (2)
1. the middle roller transmission device of ring throstle, comprise middle roller head section (1), middle roller travelling gear (2), middle roller slide, it is characterized in that this middle roller slide (3) is the supporting that is positioned at middle roller travelling gear (2) both sides, its top is the rigidity slide that fuses.
2. the middle roller transmission device of ring throstle as claimed in claim 1 is characterized in that the supporting that is positioned at middle roller travelling gear (2) both sides adopts needle bearing.
