Description

High-sealing-performance and high-lubricity lathe spindle structure

Technical Field

The utility model relates to a lathe spindle processing technology field, in particular to high lubricity lathe spindle structure of high leakproofness.

Background

The main shaft means a shaft that receives power from an engine or a motor and transmits it to other members. The principal axis is also called the "optical axis" and is the abbreviation of the "principal optical axis", the diameter of symmetry in the optical train. For example, the major axis of the sphere is a straight line passing through the center of the mirror surface and perpendicular to the mirror surface. The principal axis of a lens or optical axis optical train is the line connecting the centers of the lens faces.

At present, a lathe spindle has some defects when in use, the lubrication of a bearing is not good, the bearing is easy to wear in the continuous operation process, the tightness of a spindle device is not good, and the spindle of a machine tool is easy to enter scrap iron during operation to cause the bearing to be incapable of operating and cause mechanical faults.

The utility model provides a high lubricity lathe main shaft structure of high leakproofness solves above-mentioned technical problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high lubricity lathe spindle structure of high leakproofness solves above-mentioned technical problem.

The utility model provides a high lubricity lathe main shaft structure of high leakproofness which characterized in that: the lathe circle axle passes main shaft, thrust ball bearing, bearing frame, felt oil blanket, turbine, bearing enclosing cover, nut, oil cup and deep groove bearing in proper order, main shaft, thrust ball bearing, bearing frame, deep groove bearing, nut and turbine are fixed to the lathe circle axle, the deep groove bearing is fixed on the bearing frame, thrust ball bearing is located between main shaft and the bearing frame, be equipped with the felt oil blanket between turbine and the nut, the bearing enclosing cover sets up in thrust ball bearing's the outside to fix on bearing frame and main shaft through the bolt of taking the flat pad, be equipped with two oil cups on the bearing enclosing cover, two oil cup mutual symmetries.

Further, the nut is a nylon nut.

Further, the felt oil seal is a wool felt oil seal.

Compared with the prior art, the utility model has the advantages that: be equipped with the bearing housing in thrust ball bearing's the outside, can seal thrust ball bearing, during the metal fillings when avoiding producing get into thrust ball bearing, cause unable normal work, deep groove bearing fixes on the bearing frame, the opposite side of bearing is equipped with the nut, be equipped with the oil blanket between nut and the turbine, can play the sealing action to deep groove bearing, avoid the metal fillings to get into turbine and deep groove bearing, cause the dysfunction, thereby influence the work of lathe, be equipped with the oil cup on the shell, can add lubricating oil in the main shaft through two oil cups, high durability and convenient operation, and good lubrication effect. The utility model relates to a simply, convenient operation, the leakproofness is good, and the main shaft lubricity is good, reduces the friction, guarantees the normal function of main shaft.
