Abstract
The utility model discloses a composite bearing used for roller on a drawing frame, which comprises a core shaft, wherein a bearing is sleeved on the core shaft, the bearing comprises a bearing inner ring which is sleeved on the core shaft, a bearing outer ring is arranged on the outside of the inner ring, a row of steel balls which are arranged in a steel ball retainer are installed between the bearing inner ring and the bearing outer ring, and two rows of quill rollers which are respectively arranged in a quill roller retainer are installed between the bearing inner ring and the bearing outer ring. The composite bearing has the advantages of reasonable structure, non-leakage, uneasy to heating, uneasy to abrade and big carrying power.
Description
Technical field:
The utility model relates to a kind of drawing frame bearing part.
Background technique:
Originally the drawing frame top roller adopts needle roller bearing without inner ring and mandrel cylindrical to form rolling friction pair with bearing part, carries out mandrel work circular movement, and the combination of this form has shortcomings such as easy oil leakage, heating, unsuitable high speed, the damage of working surface fatiguability.
Chinese patent 03279460.6 adopts to add interior cover and deep groove ball bearing structure, has solved leakage of oil heating, unsuitable problem at a high speed, and mandrel has also been realized never wornout, but its bearing capacity still has deficiency.
Summary of the invention:
That the purpose of this utility model is to provide is a kind of rational in infrastructure, oil-proof, be difficult for heating, not easy to wear, the compound bearing of drawing frame top roller that bearing capacity is big.
Technical solution of the present utility model is:
The compound bearing of a kind of drawing frame top roller, comprise mandrel, bearing set on the mandrel, it is characterized in that: bearing comprises the bearing inner race that is sleeved on the mandrel, bearing inner race is provided with bearing outer ring outward, between bearing inner race and bearing outer ring, adorn a row and be arranged on steel ball in the steel ball retainer, between bearing inner race and bearing outer ring, adorn two rows and be separately positioned on needle roller in the needle roller retainer separately.
Two rows are separately positioned on the needle roller in the needle roller retainer separately, the two-end part between the inside and outside circle of bearing; One row is arranged on the steel ball in the steel ball retainer, the intermediate portion between the inside and outside circle of bearing.Bearing inner race adopts conical surface to cooperate with mandrel, and range of taper is 1: 5～1: 50.Bearing two ends dress locating piece, the mandrel end is provided with the fastening screw trip bolt device.In bearing inner race, be positioned at position, mandrel outer end, be provided with the dismounting screw.
The utility model is rational in infrastructure, oil-proof, be difficult for heating, not easy to wear, bearing capacity is big.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
