Description

Technical Field

[0001] The invention relates to the technical field of air-jet spinning machines, and in particular to a spinning cup motor for directly driving a spinning cup to rotate and a method for installing the same. Background Art

[0002] The spinning methods are mainly divided into ring spinning and open-end spinning. Open-end spinning was originally used for denim, but now its use has been expanded to bedding, knitted fabrics, woven fabrics and other occasions. With the increase in the rotor speed, open-end spinning has replaced the application of ring spinning in more and more occasions. Open-end spinning machines are divided into semi-automatic joint open-end spinning machines and fully automatic joint open-end spinning machines according to the different jointing methods. Each open-end spinning machine has 300-600 rotor bearings. If the rotor is single-motorized, each open-end spinning machine will use 300-600 rotor motors.

[0003] Semi-automatic piecing air spinning machine - manual assistance, automatic piecing at normal spinning speed according to the program. Semi-automatic piecing air spinning machine (hereinafter referred to as "semi-automatic") generally adopts double-row centripetal ball rotor bearings and tangential belt transmission. Its advantages and disadvantages are derived from this: the structure is simple, but the spinning speed must be consistent with the piecing speed, the piecing efficiency is low at high speed and the piecing quality is poor. In addition, no matter which type of semi-automatic air spinning is around 100,000 revolutions, the tangential belt will vibrate and the transmission will be unstable. The general solution is to increase the tangential belt pressure, but this will increase energy consumption and shorten the life of the tangential belt and bearings. In addition, the automatic lubrication system is generally not used, and the refueling cycle is long (the main reason for the short bearing life), so the long-term actual rotor speed of almost all semi-automatic air spinning is maintained below 105,000rpm.

[0004] Everyone in the textile industry knows that if the spinning machine speed in the final process is increased by 10%, the factory's net profit may double. Due to the instability of high-speed transmission and serious bearing loss, the actual rotor speed of the existing belt-driven semi-automatic air-spinning has a ceiling obstacle of 110,000 rpm per minute. The price of a domestic semi-automatic single spindle is 2,500-4,000 yuan; 110,000rpm-150,000rpm can only rely on imported fully automatic air-spinning equipment, and the price of a single spindle is 11,000-15,000 yuan. In a sense, it can be said that in order to achieve a rotor speed of 110,000-150,000 rpm, textile factories are willing to spend several times more to buy high-priced equipment.

[0005] Fully automatic piecing air spinning machine - manipulator (industrial robot) assists in speed reduction piecing, high-speed spinning Fully automatic piecing air spinning machine (hereinafter referred to as "full automatic") has two transmission modes for the rotor bearing, one is radial support wheel + axial air floating transmission mode (hereinafter referred to as support wheel type); the other is magnetic suspension bearing + permanent magnet motor (hereinafter referred to as magnetic suspension motor). In order to achieve high-speed spinning while still having good piecing efficiency and piecing quality, these two fully automatic machines both adopt the method of "speed reduction piecing, high-speed spinning".

[0006] Because single-motor transmission can realize multi-variety production with low power consumption per unit output, and because of the large speed reduction joint, lower grade cotton can be used (because the bearing of the support roller type uses compressed air to assist axial support, the energy consumption is higher, and the speed reduction joint of the support roller type has a limited range, so lower grade cotton cannot be used), but due to the high cost of magnetic levitation bearings + permanent magnet motors, high technical difficulty of high-speed permanent magnet motors, and high intellectual property barriers, there is no second company that has officially launched a single-motor driven air spinning machine.

The heat dissipation rib plate cylinder is provided with radially arranged top screw holes 31, and the top screw holes 31 cooperate with the housing top screw holes 33 arranged on the housing, so as to facilitate the front top screw 38 or the rear top screw to pass through and fix the C-shaped ring from the radial direction. That is, the heat dissipation rib cylinder is set as a discontinuous cylinder, and its cross section forms a slit, and two holding holes are set at the corresponding positions of the slit, and holding bolts and nuts are set at the holding holes. When the housing is positioned, tighten the holding bolts and nuts to complete the fixing of the housing. The heat dissipation rib plate or the housing can be fixedly connected to the air-spinning machine, and other components are attached to it. However, it is obviously the best solution to fix the heat dissipation rib on the whole machine. When the heat dissipation rib plate and the whole machine are fixedly connected, two oil filling pipes and several cooling air pipes are arranged on the heat dissipation rib plate cylinder, so that it is convenient to plug and unplug the motor housing, and there is no need to remove these pipes.

When the front bearing sleeve 18 enters the front hole 6 of the housing, the front bearing positioning mark 61 corresponds to the housing positioning mark 62 until the front bearing 5 enters the predetermined axial position. Arriving at this position indicates that the concave-convex matching mechanism between the rear bearing 7 and the rear axial positioning flange 54 is correctly matched and in place, so that the front bearing lubrication hole 16 and the front lubrication hole 37 of the housing are matched, connected and positioned;

[0044] S2: Then tighten the front top screw 38 to make the first C-shaped ring 35 hug the front bearing sleeve 18, and tighten the rear top screw 43 to make the second C-shaped ring 40 hug the rear bearing sleeve 22, so as to complete the fixing of the overall structure of the plug-in integrated rotor bearing device 1 in the housing 2;
