Abstract

A kind of method that relies on centrifugal force to be lubricated.The centrifugal force that relies on the high speed rotating part to produce, oil is thrown away formation from be opened in its inner oil duct lubricated.Avoid the churning loss of the too high generation of oil sump liquid level, also avoid using lubricating pump.

Description

Centrifugal lubricating mode

This is the invention of mechanical field about lubricating method.In the conventional lubrication method, the need of oil immersed type are dipped into lubricated part with higher pasta, thereby churning loss is bigger; Driving type then need use lubricating pump, complex structure and cost is higher.For making pasta can very lowly need not to be dipped into lubricated part to avoid churning loss, also need not use the lubricating pump system, and can proper lubrication, the inventor proposes centrifugal lubricating mode.

Schematic representation Fig. 1 is a sectional drawing.1. be rotating object, radially have radial direction oil 2. in it and can be bore the hole, lead to the axial oil duct 2a that drives vertically in the axle center, lubricant oil in the 2a, when 1 high speed rotating, throw away through exporting 3 in the effect lower edge of the centrifugal force direction of arrow through radial direction oil 2, lubricated 1 surface reaches the part with 1 associated.Fig. 1 disclosed rely on centrifugal force and part inside radially, axially oil duct is thrown to the principle that part surface is lubricated with oil, i.e. the principle of centrifugal lubricating mode.No matter part is to do pure rotational motion, still does motion other space or the plane, as long as have centrifugal force, all can utilize centrifugal force and be opened in the oil duct of part inside, with oil from the part absorbed inside to part surface and throw away form lubricated.

Schematic representation Fig. 2 is the typical structure that explanation throws away oil in oil duct leads to rotating part from oil sump again.The axle that fuses with cam 6, gear 7 is 5 in bearing 9 is supported on support 4.Radially have the radial direction oil 8 of leading to the surface in the cam 6, have radial direction oil 8(in the gear 7 too and lead to the tooth bottom of gear), radial direction oil 8 is communicated with axial oil duct 8a, oil nozzle 10 is installed in the support 4, put in to its outer garden dynamic seal (packing) of one end in the end of

axle

5,10 and 5 is coaxial lines, have oil duct 11 in 10,11 have been communicated with the interior grease chamber 12 of axial oil duct 8a and support 4 in 5,12 are communicated with oil sump 14 through support internal oil channel 13, when 5 high speed rotating, the pull of vacuum that the centrifugal force that is produced forms is drawn onto grease chamber 12 from oil sump 14 through oil duct 13 with oil, suck axial oil duct 8a in 5 from grease chamber 12 through oil nozzle 10 internal oil channels 11 again, be thrown to the surface of part 6.7 through radial direction oil 8, formation to part surface and related part (as with the gear of 7 engagements) lubricate.Arrow has shown that lubricant oil throws away from radial direction oil among the figure.

Oil nozzle 10 is " the oil duct connectednesses " that connect the interior oil duct of interior the oil duct of moving parts and stationary components (or another moving parts), and it is interior and stretch within the stationary components (or another moving parts) that it also can be installed in moving parts.Principle is the same.

If the centrifugal force of high speed rotating part formation does not also have big to can then adopting " oily car " shown in Figure 3 device from the degree of oil sump oil suction.Fig. 3 is schematic representation (sectional drawing).The 15th, the part that slowly runs as shown by arrows with direction is fixed with the oil dipper 16,17,18 that has towards 15 surface depression at outer surface on it.15 when forwarding shown position to, oil dipper 17 is in and utilizes its depression filling position from oil sump 21, rotation along with 15, during near forwarding oil dipper 18 to position, oil in the oil dipper just flows in the axial oil duct 19a along the radial direction oil 19 that communicates with oil dipper and axial oil duct 19a, and 19a is communicated with grease chamber (12) through oil duct through an oil nozzle (10) also as shown in Figure 2, thereby oil is led in the high speed rotating part oil duct, throw away through centrifugal force again.Ball 20 is placed in the axial oil duct 19a, and 15 when rotating, and 20 can block the inside opening of position radial direction oil down by gravity, makes the oil in the axial oil duct not flow back to oil sump along down radial direction oil.When only establishing a radial direction oil, can be without ball 20.The part that slowly runs can be the gear that slowly runs, axle etc.Oil structure should be contained in do not bump other part, again can be in the position of oil sump charge of oil.

13 support wall internal oil channel among class such as Fig. 2, during the boring trouble, also available establishing is loaded on outside oil pipe (as the copper pipe nylon tube) replacement.

Dynamic seal (packing) among Fig. 2 between the outer garden and 5 of class such as oil nozzle 10 inserting ends also can design not really sternly, promptly leaves big gap, and oil can be flowed out from this gap, and the double part that can lubricate as bearing 9 flows back to oil sump again.

Like this, utilize method of the present invention, the oil sump liquid level can be very low, avoids contacting the high-speed motion part and cause churning loss, also without lubricating pump, and can lubricate reliably.

Claims
