Description
Technical field
The utility model belongs to yarn finish field of mechanical technique, especially related with bevel gear with a kind of four twist spindles.
Background technique
The structure of four twist spindles includes upper and lower two spindles connected by steering mechanism, and the upper spindle blade of upper spindle is under
A twisting plate is respectively set on the lower ingot rod of spindle, lower ingot rod is all concentrated by same root tengential belt by main motor and provides power drive
It is dynamic, it realizes that upper spindle blade is inverted with respect to lower ingot rod by steering mechanism's transmission turning, one turn of yarn plus four is twisted to realize.It is existing
There is four twist spindles steering mechanism to support the structure of upper spindle blade and lower ingot rod using the switching of upper bevel gear, needs to occupy spindle blade under
Supporting and space between spindle blade, and participate in bearing the weight of spindle, when high-speed motion, upper spindle blade was easy to produce shaking, turning machine
Structure is easy to produce vibration, and influences each other, or even is easy to produce resonance, causes entire spindle vibration larger, can not adapt to high speed
Operating；Bevel gear material is steel, is metal friction between gear, noise is big, quick abrasion, and the service life is short.
Utility model content
The utility model aim aims to solve the problem that the bevel gear of existing four twist spindles steering mechanism need to occupy spindle blade and lower ingot
The connection supporting and space of bar, bevel gear noise be big, quick abrasion defect, provides a kind of four twist spindles suitable for running at high speed and bores
Gear.
For this purpose, the utility model uses following technical scheme: a kind of four twist spindles are with bevel gear, characterized in that the cone
Gear includes metallic framework and injection molded in the plastics gear ring on skeleton, and skeleton includes having the cylindrical part of inner cavity and being connected to
The flange portion of cylindrical part top and diameter convex offers the annular recess that at least one of diameter concaves, flange portion edge on skeleton
It circumferentially is provided with multiple limit holes and screw hole, the wheel rim of gear ring is bonded with the flange portion bottom surface, is formed on the wheel rim of gear ring
It protrudes into the pillar of the limit hole and is caught in the bulge loop of the annular recess, circumferential direction and axis are carried out to gear ring by pillar and bulge loop
To limit.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The gear ring material is PEEK plastics.
The limit hole be through-hole, limit hole top aperture be the bellmouthed orifice of big mouth upward, pillar top be with
The trumpet-like head of limit hole top aperture corresponding matching can form axial grip limit to gear ring.
The cylindrical part bottom end is formed with the position limiting convex ring to inner cavity radial direction convex, can be to other components of four twist spindles
Axial limiting effect is formed, bevel gear function is increased, simplifies four twist spindles structure.
The utility model can achieve it is following the utility model has the advantages that 1, using cylindrical part top connection evagination flange arrangement, lead to
The screw hole crossed in cylindrical part inner cavity and flange portion can form jacket-type installation, and spindle blade and lower ingot rod directly supports formula in realization
Structure adapts to the space requirement of four twist spindles steering mechanism, avoids steering mechanism from bearing upper spindle gravity, when reduction runs at high speed
Generate vibration；2, bevel gear is molded gear teeth structure using skeleton, uses PEEK special plastic as gear ring material, improves wear-resisting
Property and thermal stability, extend service life, reduce noise, have adapted to four twist spindles and have run at high speed requirement；3, pass through setting
Pillar and limit hole cooperation circumferential position limiting structure, bulge loop and annular recess cooperation axial limit structure, improve gear ring and
The binding force of skeleton improves bevel gear structural stability, adapts to the requirement that runs at high speed.

Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1 to 4, the utility model includes metallic framework 1 and injection molded in the PEEK plastic teeth on skeleton
Circle 2, skeleton 1 includes the cylindrical part 14 with inner cavity and the flange portion 13 for being connected to cylindrical part top, offers twice on skeleton 1
The annular recess 15 that diameter concaves, flange portion is circumferentially arranged, and there are three limit hole 12 and three screw holes 11, and screw hole 11 is for twisting
Dress connect the screw of fastening with other components, and limit hole 12 is through-hole, and 12 top aperture of limit hole is the loudspeaker of big mouth upward
The wheel rim in shape aperture, gear ring 2 is bonded with 13 bottom surface of flange portion, and the pillar 22 for protruding into limit hole 12 is formed on the wheel rim of gear ring 2
With the bulge loop 21 for being caught in annular recess 15, pillar top is the trumpet-like head with limit hole top aperture corresponding matching, is passed through
Pillar and bulge loop carry out circumferential and axial limit to gear ring.14 bottom end of cylindrical part is formed with the position limiting convex ring to inner cavity radial direction convex
16, can other components of four twist spindles be formed with axial limiting effect, increase bevel gear function, simplify four twist spindles structure.
