Description
Technical field
The present invention relates to worm-gear speed reducer, the upper bearing (metal) self-loopa oil supplying device of especially rectilinear worm-gear speed reducer.
Background technique
The feature that worm-gear speed reducer is all little with its stable drive, vibration, impact and noise, reduction speed ratio is large, versatility is wide, can use with various mechanical equipment coordination, is favored widely in various machine driven system.The bearing lubrication of speed reducer is very important project, and lubricate this on the one hand about bearing in reduction gears at present, Patents and document are very rare, in the bearing lubrication of the worm-gear speed reducer of gear type speed reducer, horizontal, only there are some to study, but the research of rectilinear worm-gear speed reducer is almost nil, its worm screw upper end bearing can only resin tapping lubrication because of the lubricant oil that cannot touch in casing.Small-sized rectilinear worm-gear speed reducer makes simple, cost is low, its upper bearing adopts grease lubrication to meet usage requirement, but large-scale worm-gear speed reducer then can only add enough lubricating grease or again supplement when overhauling when new mounting equipment, cannot add in using process, be difficult to like this meet relevant industries to the bearing lubrication requirement under the long-term high load service condition of speed reducer, the bearing causing speed reducer to cause because of upper bearing (metal) greasy property difference is downright bad, the problem that the speed reducer life-span declines is very general, thus bring great puzzlement to speed reducer manufacturer and user.
Summary of the invention
For overcoming the deficiency that in above-mentioned manufacture and using process, rectilinear worm-gear speed reducer exists, the object of the present invention is to provide the self-loopa oil supplying device that a kind of simple possible, fuel delivery are little, required drive is little.
For achieving the above object, the technical solution used in the present invention is:
Utilize the power transmission of worm-gear speed reducer: worm-wheel shaft to side go here and there the grooved cam mechanism of a roller direct acting relay piston, be combined with piston sleeve with piston assembly, outer cylinder body, cylinder cap; Inlet port and force feed mouth is had in the relevant position of piston sleeve and outer cylinder body, and be provided with one-way valve and filter screen at inlet port place, pressure oil port is equipped with transport pipe, the bearing part of required lubrication is directly stretched to by the siphunculus groove offered in the bottom of speed reducer blind flange, and being provided with return port at another place of blind flange, position becomes asymmetric relation with siphunculus groove.When worm-gear speed reducer works, worm gear drives grooved cam mechanism kinematic, thus drives piston stroking upward, the one-way valve opens at inlet port place, and the lubricant oil in case is inhaled in piston sleeve by filter screen; When cam driven descent of piston, the closed check valve at inlet port place, lubricant oil is pressed in transport pipe by force feed mouth by piston, worm screw upper bearing member is directly supplied by the siphunculus groove bottom blind flange, final lubricant oil is flowed in cabinet by upper bearing (metal) and return port, achieves the self-loopa fuel feeding of speed reducer upper bearing member.
In order to assurance device balance, the thickness of the large radius of described grooved cam is less than the thickness at minor radius place.
The diameter of described piston sleeve and highly very little, coordinates suitable cam profile, to meet the requirement of small flow needed for bearing lubrication, and piston sleeve and outer cylinder body in the height direction under all have surplus, eliminate the impact of straight-moving mechanism.
The theoretical delivery of the upper bearing (metal) parts circulating oil supply device of described rectilinear worm-gear speed reducer worm screw is about 10ml/min, and actual flow can be less than theoretical delivery, meets oil mass needed for bearing lubrication.
The beneficial effect that the present invention has is: the invention enables the lubrication of the upper bearing of rectilinear worm-gear speed reducer to be improved, and is applicable to large-scale rectilinear worm-gear speed reducer.

Embodiment
A kind of upper bearing (metal) self-loopa oil supplying device of rectilinear worm-gear speed reducer, overall structure as shown in Figure 1, mainly comprises rectilinear worm-gear speed reducer housing 1, speed reducer blind flange 2, siphunculus groove 3, spill port 4, upper bearing (metal) parts 5, worm screw 6, worm gear 7, grooved cam 8, worm-wheel shaft 9, the core apparatus 10 of circulation fuel feeding, transport pipe 11.
The core apparatus of described worm gear and self-loopa fuel feeding, as shown in Figure 2, described grooved cam is arranged on the worm gear of speed reducer by key, and then direct acting piston assembly 13 passes through the core apparatus that roller 12 and standard Placement and grooved cam form self-loopa fuel feeding; What coordinate with piston assembly has piston sleeve 16, in the outer cylinder body 17 finally piston sleeve press-in and reducer shell are cast as one, when installing direct acting piston assembly, the cylinder cap 18 matched with outer cylinder body is first equipped with in its bar portion, deviates from piston sleeve to prevent piston assembly; Have inlet port and force feed mouth in the corresponding position of piston sleeve and outer cylinder body, and inlet port place is provided with one-way valve 14 and filter screen 15.When worm-gear speed reducer works, worm gear drives grooved cam mechanism kinematic, thus drives piston stroking upward, the one-way valve opens at inlet port place, and the lubricant oil in case is inhaled in piston sleeve by filter screen; When cam driven descent of piston, the closed check valve at inlet port place, lubricant oil is pressed in transport pipe by force feed mouth by piston, worm screw upper bearing member is directly supplied by the siphunculus groove bottom blind flange, final lubricant oil is flowed in cabinet by upper bearing (metal) and return port, achieves the circulation fuel feeding of speed reducer upper bearing member.
The concrete accessory at the inlet port place of described self-loopa oil supplying device, as shown in Figure 3, the inlet port place of piston sleeve and outer cylinder body is provided with one-way valve and filter screen, when grooved cam mechanism drives piston assembly up, the one-way valve opens of inlet port, lubricant oil enters in piston sleeve, when grooved cam mechanism drives piston assembly descending, the closed check valve of inlet port, makes lubricant oil enter transport pipe by force feed mouth, finally leads to the upper bearing (metal) parts of required lubrication.
Siphunculus groove on described speed reducer blind flange and spill port, as shown in Figure 4, because speed reducer blind flange is just in time pressed on the bearing part of required lubrication, this blind flange has siphunculus groove and spill port, lubricant oil is directly supplied the bearing part of required lubrication by transport pipe by siphunculus groove, finally flow back in cabinet; In addition, too many with oil mass in the space of blind flange for avoiding on bearing, blind flange is provided with spill port, excessive oil is flowed in cabinet by spill port, forms a self-circulating device.
Implementing process of the present invention: according to above-mentioned mode of execution, casting worm-gear speed reducer housing, processing grooved cam and piston assembly and cylinder cap, circulating oil supply device and worm-gear speed reducer are assembled into one, power by worm gear makes circulating oil supply device work, achieves the lubrication of the upper bearing of rectilinear worm-gear speed reducer.Contrast traditional grease lubrication, recycled the lubricant oil in decelerating chassis, the lubrication effect of rectilinear worm screw upper bearing can be improved.
Above-mentioned embodiment is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
