Novel oil-saving spindle with dynamic self-rotating airflow gap sealing

Abstract

The invention discloses a novel oil-saving spindle with dynamic self-rotating airflow gap sealing, and belongs to the textile machinery industry. Lubricating oil is sealed into an inner cavity of a spindle by dynamic self-rotating airflow gap sealing technology. The novel oil-saving spindle is composed of a spindle rod, a spindle disk, an air gap sealing groove, a rotary airflow bearing sealing cover, a polymer sealing ring, a sealing groove, an upper bearing, an upper bearing seat, a gasket, a spindle foot, an elastic tube, a vibration absorbing coil spring, a spindle bottom, a spindle hook joint part and an axial spring. Spindle oil non-normal loss results from the spindle structure design. In the prior art, the upper bearing of the spindle is open type oil mist thin film lubricating, and the spindle oil evaporates into the atmosphere in an oil mist mode to cause loss. The unique dynamic self-rotating airflow gap sealing technology is used to solve the existing technical shortcomings, and the novel oil-saving spindle is applicable to the transformation of current different spindle oil-saving technologies. The spindle oil filling cycle extends from 3 months to 12-24 months. The operation cost of equipment is reduced; the labor intensity is reduced; the employment of enterprises is reduced; the workload of a spindle oil filling machine is reduced; the needs of spindle oil saving and the like are met.

Description

technical field [0001] The invention belongs to the manufacturing industry of special parts of textile machinery. The dynamic autorotation airflow gap sealing technology is applied to the high-speed rotating operation of the spindle, and the dynamic autorotation airflow gap sealing is implemented on the spindle lubricating oil, and the spindle lubricating oil is sealed by the dynamic autorotation airflow gap sealing technology. It is sealed in the inner cavity of the spindle, thereby prolonging the refueling cycle and service life of the spindle. It is a new type of fuel-saving spindle with a dynamic self-rotating airflow gap seal. Background technique [0002] Spindle is a special part of textile machinery that rotates at high speed on the spinning frame of the textile industry. There are hundreds of millions of spindles in operation across the country. It is the pursuit of textile machinery manufacturing and textile enterprises to develop and adopt spindles that are adapta...

Problems solved by technology

[0014] From the point of view of the structure design of a fuel-saving spindle with patented technology, the sealing groove on the bearing sealing cover is a concave annular groove in the inner hole, and no other sealing medium is installed, and the bearing sealing cover is relatively close to the spindle rod. Large gap fit, the spindle bar itself runs at high speed, and there is no mechanism to prevent the lubricating oil from climbing up the surface of the spindle bar at the stationary bearing seal cover relative to the spindle foot, so this structure cannot implement effective sealing effect, and the lubricating oil will still flow along the upper bearing. The surface of the spindle bar climbs up and penetrates the outer space of the spindle

In essence, the upper bearing, bearing sealing cover, sealing groove, and the spindle rod of the high-speed rotating part are still open structures, and no sealing technology is used, and the actual fuel saving effect is not ideal
