Sealing structure of spindle insert and spindle insert provided with same

Abstract

The invention discloses a sealing structure of a spindle insert. The sealing structure comprises a bearing seat, a spindle bearing arranged in the bearing seat, a sealing cap, a washer and a seal ringlocated between the sealing cap and a washer, wherein the sealing cap and the washer are arranged in the bearing seat, the seal ring is provided with a central hole for a spindle rod to penetrate through, and the inner circumferential face at the central hole is provided with a spiral groove for blocking lubricating oil. The sealing structure of the spindle insert is provided with the seal ring with the spiral groove, the spiral groove has the blocking effect on lubricating oil, and the lubricating oil is pushed into the spindle insert, so that the lubricating oil is not gathered at an upperbearing of the spindle insert, lubricating oil leakage is decreased, and the oil supplementing period of a spindle is prolonged.

Description

technical field [0001] The invention belongs to the technical field of spinning equipment, in particular, the invention relates to a sealing structure of a core and a core having the same. Background technique [0002] The spindle is one of the main components of twisting and winding on the spinning frame, and it is an assembly with a slender rotary shaft supported by two points as the main body. [0003] The spindle bladder of the existing spinning spindle is mainly composed of a shock-absorbing coil spring, an elastic tube, a positioning sleeve, a bearing seat, a spindle bearing, a sliding bearing, a spindle bottom pad and a flat spindle bottom. The spindle bearing and the bearing seat constitute the upper support, and the elastic tube and The sliding bearing constitutes the lower support, and the bottom of the flat ingot is located below the sliding bearing. [0004] The spindle rod of the spinning spindle rotates at high speed and accompanied by high-frequency vibration...

AI Technical Summary

Problems solved by technology

[0005] The oil storage space of the existing spun spindles is limited, the oil replenishment cycle of the sharp pole spindles is generally 10 days to 15 days, and the high-speed high-performance flat-bottomed spindles generally need to be refueled after about 3 months of operation. The refueling operation is more complicated and the workload is heavy.

Stoppage for refueling will result in loss of output, oil consumption and increased labor. Therefore, the length of spindle lubricating oil refueling cycle will directly affect the spinning cost and production efficiency of textile enterprises.
