Description

Technical Field

[0001] The utility model relates to the technical field of spinning machine equipment, in particular to a main shaft mounting mechanism for a spinning machine. Background Art

[0002] Pulleys are hub-type components primarily used for long-distance power transmission, such as in small diesel engine output and machining equipment. Pulleys are made by spinning a cylindrical material through a spinning machine to create a surface groove. The cylindrical material is then mounted on a corresponding mold and placed near a spinning wheel, which is rotated by a spindle mechanism. Grooves of varying shapes and depths are spun using vertical and horizontal spacing adjustments to achieve the desired spinning effect.

[0003] During pulley processing, the traditional spindle mechanism consists of a spindle rotatably mounted on a spindle mounting base, which is rotatably mounted within the base via several parallel, spaced-apart bearings. However, because pulley processing requires vertical and horizontal spacing adjustments, the spindle of the spinning machine is subject to forces acting in different directions, both horizontally and longitudinally. Simply using parallel bearings for connection results in an unstable spindle installation, which reduces the spindle's service life, compromises the spinning results, and affects the pulley production quality.

[0004] Therefore, on the basis of ensuring the normal use of the spindle, the research purpose of this utility model is to design a spindle installation mechanism for a spinning machine that can further improve the stability of the spindle installation through structural improvements, thereby ensuring the spinning quality and service life.

[0034] The bearing assembly includes a horizontal bearing 3 and an inverted inclined bearing 4 installed in the main bearing seat 1 and sleeved up and down and fixed on the outside of the main shaft 2. The middle part of the inner side of the main bearing seat 1 is embedded with a front bearing seat 5 with an L-shaped cross section through a corresponding chamfer limit.
