Abstract
A kind of lubricating arrangement of novel worm drive lead screw pair, it is characterised in that: at described nut two ends, oil storage set is installed.In oil storage set, side ring surface forms shoe cream room with leading screw, nut side.By grease in shoe cream room to lead screw pair uniform application lubricating oil.Outside described oil storage set, elastic sealing ring is installed.Elastic sealing ring endoporus matches with threads of lead screw contact surface, and forms relative motion with leading screw, and the lubricating oil escaped after being extruded takes in shoe cream room, and by the oilhole of nut, it is achieved the oil pressure in the lubricant reservoir of nut two ends, the balance of oil mass.Oil nozzle can make-up oil at any time simultaneously.Overcome the shortcoming that under high speed, case of heavy load, drip lubrication can not set up effective elastohydrodynamic lubrication film, reach again timely oiling simultaneously, reduce lubricating oil and damage leakage, it is not necessary to often make-up oil, solve the problem that worm drive lead screw pair even lost efficacy because of lack of lubrication heating.
Description
Technical field
This utility model relates to the lubrication technology of worm drive lead screw pair, the lubricating arrangement of a kind of novel worm drive lead screw pair.
Background technology
Worm drive lead screw pair is the same with other transmissions, should be lubricated between the contact surface of transmission, and to reduce the frictional dissipation of transmission, the extraneous foreign body such as dust to be avoided enters in transmission.Therefore, in addition to dust-proof seal ring or protective cover being installed at leading screw exposed parts, in addition it is also necessary to the contact surface of transmission is lubricated.One of traditional lubrication mode of worm drive lead screw pair, is periodically to be applied to grease be lubricated in the contact surface of transmission.But grease escapes the contact surface of transmission after being touched face extruding, it is relatively big that lubricating oil damages leakage, and in short-term, lubricating oil cannot self-supporting supplement again, the heating of worm drive lead screw pair is caused even to lose efficacy.The traditional lubrication another way of worm drive lead screw pair is drip lubrication.And drip lubrication is under high speed, severe duty, it is difficult to set up effective elastohydrodynamic lubrication film.
Avoid drip lubrication can not set up the shortcoming of effective elastohydrodynamic lubrication film, overcome and smear the deficiency that lubricating oil or lubricating damage leakage is bigger, be technical problem urgently to be resolved hurrily in worm drive lead screw pair lubrication.
Number of patent application: 201310077939.3 " a kind of lubricating device and lubricating method of ball screw pair " patent, is improved above-mentioned technical problem.But its box body installed is sleeved on leading screw cylindrical, the grease smeared escapes contact surface after being touched face extruding, and lubricating oil damages the big problem of leakage and do not solves.
Summary of the invention
Technical problem to be solved in the utility model is to provide the lubricating arrangement of a kind of novel worm drive lead screw pair, overcome the shortcoming that under high speed, case of heavy load, drip lubrication can not set up effective elastohydrodynamic lubrication film, reach timely oiling simultaneously, reduce lubricating oil and damage leakage, it is not necessary to often supplement.
In order to solve above-mentioned technical problem, this utility model provides the lubricating arrangement of a kind of novel worm drive lead screw pair.Realizing with following technical scheme: the lubricating arrangement of a kind of novel worm drive lead screw pair, including nut, leading screw, oil storage set, elastic sealing ring, oil storage set is installed at described nut two ends.Nut is provided with oil filler, and oil filler is provided with fuel filler neck.Described nut is provided with the oilhole running through nut two ends, oil filler is connected by described oilhole with chamber, side ring surface in oil storage set, described oil storage set is sleeved on screw mandrel cylindrical, in oil storage set, side ring surface forms shoe cream room with leading screw, nut side, the outside of oil storage set installs elastic sealing ring again additional, elastic sealing ring endoporus matches with threads of lead screw contact surface, and with the motion of lead screw pair, the lubricating oil income shoe cream room of transmission contact surface is escaped after being extruded, described elastic sealing ring endoporus matches with threads of lead screw contact surface, and forms relative motion with leading screw ".
This utility model, installs oil storage set at nut two ends.In oil storage set, side ring surface forms shoe cream room with leading screw, nut side.By grease in shoe cream room to lead screw pair uniform application lubricating oil.And elastic sealing ring endoporus and threads of lead screw contact surface match, and forming relative motion with leading screw, the lubricating oil escaped after being extruded takes in shoe cream room, and by the oilhole of nut, it is achieved the oil pressure in the lubricant reservoir of nut two ends, the balance of oil mass.Oil nozzle can make-up oil at any time simultaneously.Overcome the shortcoming that under high speed, case of heavy load, drip lubrication can not set up effective elastohydrodynamic lubrication film, reach again timely oiling simultaneously, reduce lubricating oil and damage leakage, it is not necessary to often make-up oil, solve the problem that worm drive lead screw pair even lost efficacy because of lack of lubrication heating.

Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.Embodiment
As shown in Figure 1, 2, for the lubricating arrangement of a kind of novel worm drive lead screw pair, it is made up of lead screw pair nut 100, leading screw 5, oil storage set 200, elastic sealing ring 3 etc..Oil storage set 200 is installed at described lead screw pair nut 100 two ends 102.Nut 100 is provided with oil filler 103, and oil filler 103 is provided with fuel filler neck 4.Described nut 100 is provided with the oilhole 101 running through nut two ends 102, and oil filler 3 is connected by described oilhole 101 with chamber, side ring surface 203 in oil storage set 200.
As shown in Figure 1,3, described oil storage set 200 is sleeved on screw mandrel 5 cylindrical, and in oil storage set 200, side ring surface 201 forms shoe cream room 6 with leading screw 5, nut side 102.The outside 202 of oil storage set 200 installs elastic sealing ring 3 again additional.Elastic sealing ring 3 endoporus matches with leading screw 5 thread contact face, and with the motion of lead screw pair, escapes the lubricating oil income shoe cream room 6 of transmission contact surface after being extruded.Described elastic sealing ring 3 endoporus matches with leading screw 5 thread contact face, and forms relative motion with leading screw 5.
