Embodiment 1

[0019] Such as Figure 1-Figure 2 As shown, the transmission shafts 2 corresponding to the spiral bevel gears 13 of the upper reducer 1 and the lower reducer 3 with the same structure are arranged in the vertical direction, and the drive shafts 2 of the upper reducer 1 and the lower reducer 3 correspond up and down and pass through ten thousand Knuckle connection, the phases of the output shafts of the upper reducer 1 and the lower reducer 3 are the same, and the steering of the two transmission shafts 2 is also the same. The gear boxes 9 of the upper reducer 1 and the lower reducer 3 are respectively provided with anti-stirring oil devices 11.

[0020] The universal joint connects the upper and lower speed reducers together, and keeps the phases of the output shafts 16 and 18 consistent during power transmission. The anti-scrambling oil device 11 divides the lubricating oil in the gear box 9 in the body 8 into two parts. When the gears are running at high speed, only the lubr...

Embodiment 2

[0023] On the basis of Embodiment 1, the upper reducer 1 is equipped with a first external forced lubrication system, the first forced lubrication system includes oil pipes, oil tank 4, filter 5 and gear pump group 7, the outlet of oil tank 4 passes through filter 5 and The gear pump unit 7 is connected to the gear case 9 of the upper reducer 1, and the oil pipe between the gear pump unit 7 and the upper reducer 1 is provided with an air cooler 6, and the temperature rise of the gear case 9 of the upper reducer 1 is lower than 45°C. The forced lubrication of the external oil tank can make the lubricating oil directly spray the gears and bearings, which can further reduce the oil level in the gearbox and further reduce the oil churning loss; the high-temperature lubricating oil of the gear box 9 passes through the outlet at the bottom of the Under the action, it returns to the oil tank, and the gear pump unit 7 sucks the filtered high-temperature lubricating oil out of the oil t...

Embodiment 3

[0025] On the basis of Example 2, the lower reducer is equipped with a second external forced lubrication system. The second external forced lubrication system is the same as the first external forced lubrication system. It can be set separately, or share a set of oil tank, filter and gear pump group, so as to reduce investment, improve efficiency and facilitate maintenance.

Abstract

The invention discloses a double-side needling machine speed reducing system and belongs to the field of double-side needling machine speed reducers. The double-side needling machine speed reducing system comprises an upper reducer and a lower reducer which are oppositely arranged and identical in structure. The double-side needling machine speed reducing system is characterized in that transmission shafts of spiral bevel gears of the upper reducer and the lower reducer are perpendicularly arranged, transmission shafts of the upper reducer and the lower reducer are vertically opposite, connected via a universal joint and identical in rotating direction, output shafts of the upper reducer and the lower reducer are identical in phase position, and oil-stir preventing devices are respectively arranged in gear boxes of the upper reducer and the lower reducer. The upper reducer and the lower reducer are integrally connected via the universal joint, phase positions of the output shafts are kept consistent during power transmission process, each oil-stir preventing device separates lubricating oil in each gear box into two parts, only the lubricating oil in the oil-stir preventing devices is stirred when gears rotate at high speed, oil stirred by the gears is low in amount, so that heating is low, and oil stirring loss is greatly reduced. The double-side needling machine speed reducing system is efficient, energy-saving, compact in structure, strong in stability, convenient to maintain, good in lubricating and sealing effects, normal in warming, and low in noise.

Description

technical field [0001] The invention belongs to the field of reducers for double-sided needling machines, and in particular provides a speed reducing system for double-sided needling machines. Background technique [0002] With the continuous development of the national economy, the needling machines in the textile industry have gradually developed from single-sided needling machines to double-sided needling machines. Double-sided needling machines are twice as efficient as single-sided needling machines. Mainly, the PSF series reducer has been successfully matched with the double-sided needling machine, which has played a positive role in promoting the development of the double-sided needling machine industry. [0003] Chinese patent 201120186879.5 discloses an acupuncture drive reducer, which consists of two first-stage helical gear reducers and two spiral bevel gear reducers, the two helical gear reducers are arranged up and down in the same direction, and the two helical...
