Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] like figure 1 As shown, a drawing roller sleeve bearing, which includes: a bearing shell 1, a bearing mandrel 2 and a screw 9; the outer circle of the bearing shell 1 is provided with an annular groove, and an oil filling hole 11 is arranged in the annular groove, and an elastic ring 12 Embedded in the annular groove and block the oil filling hole 11, the inner hole of the bearing shell 1 is provided with two R-shaped inner channels, and one end of the bearing mandrel 2 is provided with a cone outer circle, the taper and size of the cone outer circle are the same as the top roller mandrel The inner taper hole of the bearing housing 1 is matched, and the non-tapered outer circle of the bearing mandrel 2 is provided with two R-shaped outer channels. The position of the outer channels matches the R-shaped inner channel of the bearing shell 1, and there is...

Abstract

The invention discloses a drawing leather roller sleeve bearing which comprises a bearing shell and a bearing core shaft. Two inner R-shaped trenches are formed in an inner hole of the bearing shell. An external cone circle part is arranged at one end of the bearing core shaft, and the taper and size of the external cone circle part are matched with those of an inner cone hole of a leather roller core shaft. Two external R-shaped trenches are formed in an external non-taper circle part of the bearing core shaft, and the position of the external trenches is matched with the inner R-shaped trenches of the bearing shell. Steel balls are arranged in the inner R-shaped trenches of the bearing shell and the corresponding external R-shaped trenches of the bearing core shaft in a sleeving mode. The steel balls are evenly spaced through holders. A sealing ring and a positioning loop are pressed into inner holes in the two ends of the bearing shell correspondingly. The sealing ring and the external cone circle part of the bearing core shaft are placed at the same end. The drawing leather roller sleeve bearing has the advantages of operation stability, low temperature rise, no oil leakage, long oil replenishing period and the like.

Description

technical field [0001] The invention relates to a special part of a draw frame, in particular to a sleeve bearing of a draw frame top roller. Background technique [0002] At present, the drawing frame drafting top roller on the roller drafting draw frame is an important drafting part, and its quality directly affects the evenness of the roving. The traditional draw frame drafting top rollers include: top roller mandrel and draw frame top roller sleeve bearings. The outer circles at both ends of the roller mandrel are respectively set in the needle roller bearings without an inner ring to form a rolling pair. During the operation of the drawing top roller, the sleeve bearing of the drawing top roller generates a large amount of heat and is prone to oil leakage. Maintenance The workload is heavy, and the quality of the sliver is not stable. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior ...
