Embodiment
Rocker arm of coal mining machine thin oil automatic centralized lubrication system, as shown in Figure 1, comprise rocking arm housing 1, lubricating pump 2 and be arranged in the rocking arm housing and comprise the multilevel gear drive mechanism of second driving shaft 3, with rocking arm housing inner chamber as lubricating oil tank, lubricating pump is installed in the rocking arm outside, and links to each other with second driving shaft cylinder side; Fuel outlet or inlet port that the rocking arm housing is provided with inlet port or the fuel outlet that is positioned at bottom, high speed chamber and is positioned at bottom, low speed chamber, the lubricating pump filler opening is communicated with inlet port on the rocking arm housing by oil inlet pipe 4, ball valve 8 and filter 9 are installed on the oil inlet pipe 4, ball valve is between filter and rocking arm housing, filter adopts CGQ magnetic oil absorption filter, the lubricating pump oil outlet is connected with each lubricating point by oil outlet tube 5, adjustable distributor 6 is installed on the oil outlet tube, and the oil outlet place of adjustable distributor sets up LQ in-line oil stream indicator 7.
As shown in Figure 2, lubricating pump 2 is the spline shaft type gear pump, and second driving shaft 3 cylinder sides are provided with internal spline, and lubricating pump adopts key to be connected with second driving shaft; Set up seal ring 11 between the end cap 10 of second driving shaft 3 cylinder sides and the flange plate of lubricating pump.
Shown in Fig. 3,4, the structure of adjustable distributor 6 comprises valve piece 6.1, is opened in a filler opening 6.2 on valve piece top and the some oil outlets 6.3 that are opened in valve piece bottom, be communicated with between filler opening and each oil outlet, each oil outlet is provided with the adjusting screw rod 6.4 of adjust flux size, and adjusting screw rod is provided with the locking nut 6.5 fastening with the valve piece.
The present invention is by namely well-designed to rocker arm of coal mining machine thin oil automatic centralized lubrication system:
1, the setting of fuel tank
With each rocking arm housing inner chamber as lubricating oil tank.
2, inlet port setting
The rocking arm inlet port of adopting day-coal is arranged on bottom, high speed chamber, the rocking arm inlet port of adopting lower floor's coal is arranged on the bottom in low speed chamber, the interchangeability of considering left and right sides rocking arm then all can arrange inlet port in the high, low speed chamber, but the on-the-spot fuel outlet that can stop up when flatly it being drained the oil as rocking arm.
3, oil pump setting
Select the spline shaft type gear pump and link to each other with the second driving shaft cylinder side of processing internal spline, the driving cog wheel pump fuel feeding that turns round when second driving shaft rotates, second driving shaft cylinder side end cap add the O RunddichtringO and link to each other with the gear pump adpting flange and guarantee the sealing of rocking arm.Because the second driving shaft rotating speed is determined, probably is 1000r/min, under this rotating speed, both guaranteed the charge oil pressure of gear lubrication pump, can prolong again its working life, the vice president needs oil mass can select the gear lubrication pump of suitable fuel delivery according to friction, thereby realizes automatic, fixed amount of oil.
4, the filtration of lubrication system
Increase little CGQ magnetic oil absorption filter and the ball valve of volume near the rocking arm inlet port, but consider that more renew cartridge is convenient with maintenance, ball valve will be added in into filter side.
5, the calculating of lubricant oil, accurately distribution and metering
Each friction pair needs oil mass can utilize the corresponding form in related domain, figure and formula to calculate.Since different to each friction pair fuel delivery, so increase adjustable fuel-flow divider at the lubricant pump oil outlet.Each oil outlet of distributor increase LQ in-line oil stream indicator can be intuitively metered fuel charge amount accurately.Adjust the accurate oil supply that adjustable fuel-flow divider is realized each friction pair by observing each friction pair oil stream indicator.
Rocker arm of coal mining machine thin oil automatic centralized lubrication system designs through this: the first, because the coal winning machine body structure is compact, and utilize rocking arm housing inner chamber as lubricating oil tank, need not to take the confined space in each chamber of coal winning machine body.The second, the setting of inlet port does not affect the interchangeability of left and right sides rocking arm.Left and right sides rocking arm such as need exchange, and the new layout of only inlet port of lubrication system need to being connected with lubricant oil connects.Three, utilize second driving shaft driving cog wheel pump running fuel feeding, charge oil pressure, stability of flow, and meet the energy-saving and environmental protection requirement.Four, utilize CGQ magnetic oil absorption filter to filter out the lubricant oil with metal granule and other impurity from the fuel tank sucking-off, effectively protected lubricating pump and promoted the turbidity test of the lubricant oil that enters each lubricating point.Five, increase the lubricants capacity that adjustable fuel-flow divider and LQ in-line oil stream indicator can reasonable distribution enters variant friction pair, avoid blindly lubricated.Fluid is in flowing state during six, owing to self oiling, and institute is so that the better cutting oil of cooler.Seven, basis
Formula (Q-flow L/min, P-pressure MPa, η-total efficiency coefficient 0.85), load P is very little when feeding lubricating point owing to lubricant oil, so the total output of above automatic centralized lubrication system can be very little, can exert an influence hardly for rocking arm cutting power size variation.And only rotate at coal mining machine roller that lubricant pump just turns round when carrying out cut, meet very much the requirement of energy-conserving and environment-protective.Eight, lubrication system architecture is compact, and lubrication effect is accurately reasonable.Therefore, the present invention can be widely used in the rocker arm of coal mining machine thin oil automatic centralized lubrication system, and can promote at the coal winning machine traveling gear, promote quality and the intelligent degree of coal winning machine, obviously reduce the coal winning machine rate of fault, the structure that makes coal winning machine more rationally, reliability is higher, and energy-conserving and environment-protective.
