Specific embodiment
More detailed description is done to the embodiment of the utility model below in conjunction with attached drawing and reference numeral, makes to be familiar with ability
The technology people in domain can implement according to this after this specification is studied carefully.It should be appreciated that specific embodiment described herein is only solving
The utility model is released, is not used to limit the utility model.
A kind of planet wheel bearing of planetary reducer, including：It bearing inner race 1, bearing outer ring 2, ball 3, sponge ring 6 and leads
To unit 4；The ball 3 is arranged on bearing inner race 1 and in the gap of bearing outer ring 2, the sponge ring 6 is arranged on bearing inner race
1 inside, sets pilot unit 4 between the bearing inner race 1 and sponge ring 6, the pilot unit 4 is inverted U shape, pilot unit 4
The end face that is contacted with sponge ring 6 of inverted U-shaped bottom end be equipped with opening, two openings on the inverted U-shaped top of pilot unit 4 are arranged on rolling
At contact slit aperture between pearl and ball, two openings on the inverted U-shaped top of pilot unit 4 are equipped with arcuate nozzle 5, described
5 top of arcuate nozzle is provided with spray-hole, and the spray-hole is made of at least three circular holes, and the bearing outer ring 2 is with being equipped with rolling
Coolant is housed between the inner ring of pearl 3；By being equipped with ball 3 between bearing inner race 1 and bearing outer ring 2 so that planetary reduction gear
At work, bearing inner race 1 is not directly contacted with machine when being rotated with bearing outer ring 2, and bearing inner race is reduced by the rotation of ball 3
1 friction generated when being rotated with bearing outer ring 2, reduces the abrasion of bearing inner race 1 and bearing outer ring 2, extends service life,
Reduce repair and the number replaced, it is cost-effective；
By being equipped with lubricating oil in 1 inside setting sponge ring 6 of bearing inner race, the sponge ring 6, when planetary reducer turns
When dynamic, sponge ring 6 is caused to oppress, the lubricating oil in sponge ring 6 is made to pass through in the circumference where pilot unit 4 flows to ball 3,
So that the lubricating oil that ball 3 contacts becomes more, reduce the abrasion of bearing inner race 1 and bearing outer ring 2, extend bearing inner race 1 and axis
The service life of bearing outer-ring 2 realizes the self-lubricating function of bearing, without manually adding lubricating oil, reduces answering for addition lubricating oil
Miscellaneous degree, it is simple and quick, and play the role of mute, reduction noise using sponge ring；
Wherein, pilot unit uses inverted U-shaped, inverted U shape so that the lubricating oil in sponge ring 6 can there are two channel
To flow to ball 3 so that the rate of outflow of lubricating oil is accelerated, and two openings on inverted U-shaped top be arranged on ball and ball it
Between contact slit aperture at so that lubricating oil can be evenly is distributed on ball 3, and 5 top of arcuate nozzle of pilot unit
Spray-hole cause lubricate oil spurts range it is wider, make full use of lubricating oil；The bearing outer ring 2 is with being equipped with the interior of ball 3
Equipped with coolant between circle, the thermal energy that the coolant avoids planetary rotating speed machine from being generated in high-speed rotation is damaged caused by bearing
Consumption, accelerated heat distribute, reduce the temperature of speed reducer, extend the service life of bearing.
It is along the circumferential direction uniformly arranged in the circle that the ball 3 forms in the gap by bearing inner race 1 and bearing outer ring 2,
And ball 3 at least sets 20；Ball is uniformly arranged so that gap smaller between ball and ball can accommodate more rollings
Pearl so that planetary reducer has more balls to participate in rotation, further reduces friction, reduces loss；The ball 3 can
To be adjusted according to practical bearing size, transformation is flexible.
The bearing inner race 1 and bearing outer ring 2 are made of high-strength aluminum alloy material die casting；Due to the proportion of aluminium alloy
It is lighter than cast iron, make the weight saving of bearing inner race 1 and bearing outer ring 2, so as to reduce the overall weight of planetary reducer, subtract simultaneously
The output hollow shaft of asteroid speed reducer is to the load of bearing, while the heat-conductive characteristic of aluminum alloy materials is than the heat transfer of cast iron
Performance is good, and the thermal energy that planetary reducer generates is made to distribute the temperature for soon, reducing speed reducer, enables the longer life expectancy of bearing and gear,
The aluminum alloy materials of high intensity also can guarantee the measuring body external force effect of high tensile when keeping out use.
The pilot unit 4 is along the circumferential direction uniformly arranged, and pilot unit 4 is at least 17；The pilot unit 4 is equal
Even setting makes lubricating oil uniformly flow to ball, makes full use of lubricating oil, reduces the waste of lubricating oil, cost-effective, and is oriented to
Unit 4 can be according to the number of the transformation flexible transformation pilot unit 4 of the number of ball 3.
The inside of the bearing outer ring 2 and the contact surface of ball 3 is equipped with dustproof groove 7, and the dustproof groove 7 is circumferentially interior uniform
Setting；The dustproof groove 7 is recessed inwardly the arc groove to be formed for medial surface, for preventing dust from entering in ball so as to influence
The effect of lubricating oil, while increase the cleanliness factor of ball.
7 bottom of dustproof groove is equipped with the Storage Box of an arc shape；The Storage Box of 7 bottom of the dustproof groove setting is used to store up
The extra lubricating oil that sponge ring 6 flows to ball is deposited, lubricating oil is avoided to flow out, while avoid the wave of lubricating oil when excessive
Take.
The above content is the further descriptions made with reference to specific preferred embodiment to the utility model, it is impossible to recognize
Determine specific embodiment of the present utility model and be confined to these explanations.For the common skill of the utility model technical field
