Spindle socket specially for textile machinery

Abstract

The spindle sleeve specially for textile machinery includes spindle, casing, inner ring, holder, steel balls, screw bolt and sealing part, and features its short conic spindle nose structure, conic connecting sleeve matching the inner ring extending step of the short cone, and the oiling cup set on the casing. The improved reasonable spindle sleeve structure can avoid the deformation of the slender spindle and friction heating caused by friction between the spindle nose and the casing, and results in long service life, high sealing, no overflow of lubricating grease and caused contamination to rubber roller and sliver. The present invention is suitable for both high speed and low speed textile machinery.

Description

technical field [0001] The invention relates to a special shaft sleeve for textile machinery. Background technique [0002] Shaft sleeves are widely used in textile machinery, especially drawing frames and combing machines. The drawing frame is a key component that determines the drafting and traction quality of the sliver when drawing the sliver. The thickness and evenness of the sliver depend on its Therefore, there are high requirements on the reasonable structure, manufacturing quality and sealing performance of the shaft sleeve. For the defects of conventional needle roller bearings without an inner ring: such as the shaft sleeve is easy to heat, and it is hot to the hand during use; easy to leak oil, the internal grease overflows, pollutes the sliver of the rubber roller, and causes the needle roller bearing to wear due to oil loss, and then Abrasion of the draw frame mandrel affects the quality of the sliver, etc., so it is only barely applicable to the actual situat...

Problems solved by technology

For the defects of conventional needle roller bearings without an inner ring: such as the shaft sleeve is easy to heat, and it is hot to the hand during use; easy to leak oil, the internal grease overflows, pollutes the sliver of the rubber roller, and causes the needle roller bearing to wear due to oil loss, and then Abrasion of the draw frame mandrel affects the quality of the sliver, etc., so it is only barely applicable to the actual situation of the low-speed draw frame. The "new shaft sleeve for the draw frame" of Chinese patent 03279460.6 adopts the advantages of double raceway bearings, And improved to a double row deep groove ball bearing with an inner ring to replace the original needle roller bearing. Due to the adoption of the inner ring bearing structure and the labyrinth dust-proof and leak-proof structure, the mandrel and the inner ring of the bearing adopt a taper combination And so on, the temperature rise is significantly reduced, the mandrel is not easy to wear, the service life is prolonged, and the working effect is better than the original, but there are still unreasonable points in this design: ①The mandrel is long and thin, and it is easy to deform and bend; ②When the bearing is worn and loose ③The sealing between the shaft head and the shell is poor, and there is a gap that makes it easy for flying flowers to enter, thereby increasing the frictional resistance and further Increased bearing wear, resulting in reduced bushing life
