Abstract
The utility model discloses a novel bearing lubrication structure on a planet gear, comprising a planet carrier, a planet pinion shaft, a bearing and a planet gear, and retainer rings, planet pinion shaft steps and space rings which are axially located at two sides of the bearing, and oil collecting rings which form oil collecting tanks with the side surfaces of the bearing and are arranged between the two sides of the bearing and the retainer rings, wherein the A surface of the oil collecting ring is higher than a bearing ball center, and is away from the planet pinion shaft at a certain distance at the same time, thereby ensuring lubricating oil to enter in the oil collecting tank and ensuring the ball to be lubricated; therefore, when oil level in a tank body is low, the planet gear is operated to any position which is departed from the oil level of the oil tank, the arrangement of the oil collecting ring can still ensure the normal lubrication of the bearing; in addition, the oil collecting ring has simple structure and convenient manufacturing.
Description
Technical field
The utility model relates to a kind of planet wheel transmission lubrication mechanism, and especially a kind of planet wheel upper bearing (metal) lubricates new structure.
Background technique
Under the horizontal installation running of the plane table thermoconductivity meter operating mode, when oil level in the casing when not being very high, after planet wheel ran to and leaves the oil sump pasta, the lubricant oil of planet wheel inner bearing adhesive tape can turn round forward and minimizing gradually along with the continuation of planet wheel, is being unfavorable for very much the lubricated of bearing in such cases.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and provides a kind of planet wheel upper bearing (metal) that can guarantee that the planet wheel inner bearing still can normally lubricate after leaving the oil sump face to lubricate new structure.
Embodiment of the present utility model is:
A kind of planet wheel upper bearing (metal) lubricates new structure, it comprises planet carrier, planet axis, bearing, planet wheel, the back-up ring of axially locating bearing both sides, planet axis step and spacer ring is characterized in that being provided with oil collecting ring between described bearing both sides and the back-up ring, the both sides oil collecting ring is oppositely arranged, and forms oil trap with the bearing side.
The A face of described oil collecting ring is higher than the bearing ball center, the A face simultaneously with planet axis at a distance of the certain interval distance.
The utility model compared with prior art, owing between bearing both sides and back-up ring, be provided with oil collecting ring, the oil collecting ring of both sides is installed relatively to make with the bearing side and is formed oil trap, the A face of oil collecting ring guarantees to be higher than the bearing ball center, simultaneously again with planet axis at a distance of the certain clearance distance, both ensured to bearing ball and provided lubricated, guarantee to have when planet wheel enters oil sump enough spaces that lubricant oil is flowed into again and be full of, therefore, even oil level is not very high in the casing, after planet wheel runs to and leaves the oil sump pasta, the lubricated of bearing still is guaranteed, overcome the defective of prior art, and oil collecting ring is simple in structure, easily manufactured.
Description of drawings
Fig. 1 has provided the utility model structural representation.
Embodiment
In conjunction with the accompanying drawings the utility model embodiment is specifically described again below.
The planet wheel upper bearing (metal) lubricates new structure, as shown in Figure 1, it comprises the planet axis 7 of mounting support in planet carrier 1, be installed in the bearing 4 on the planet axis, bearing inner race one side is made axially locating with planet axis 7 steps, opposite side is made axially locating with spacer ring 6, this spacer ring is set on the planet axis, stretch in the annular groove that inserts planet carrier 1 its outer end, between the back-up ring 2 of bearing outer ring axially locating and the bearing 4 oil collecting ring 5 is set, the oil collecting ring of both sides is oppositely arranged, and forms oil trap 8 with the bearing side, and the lubricant oil in the oil trap provides lubricated for bearing.In order to guarantee the sufficient lubrication of bearing, described oil collecting ring A face design has 2 requirements: 1. the A face must be higher than the bearing ball center, guarantees that ball is lubricated; 2. the A face must have the certain clearance distance at a distance of planet axis, and the A face could guarantee like this that to the big footpath of planet axis centre distance fitness for purpose greater than the bearing ball inner ring lubricant oil can flow in other words, reaches the needs that guarantee bearing lubrication.
Be installed in that circle is processed with two road annular grooves in the planet wheel 3 on the bearing 4, in order to two back-up rings 2 to be installed, back-up ring 2 is used for the location set oil ring, and prevents that planet wheel from moving axially.
The utility model oil collecting ring 5 is simple in structure, easily manufactured.
Claims (2)
1, the lubricated new structure of a kind of planet wheel upper bearing (metal), it comprises planet carrier (1), planet axis (7), bearing (4), planet wheel (3), the back-up ring (2) of axially locating bearing both sides, planet axis step and spacer ring (6) is characterized in that being provided with oil collecting ring (5) between described bearing (4) both sides and the back-up ring (2), the both sides oil collecting ring is oppositely arranged, and forms oil trap (8) with the bearing side.
2, the lubricated new structure of planet wheel upper bearing (metal) according to claim 1 is characterized in that the A face of described oil collecting ring (5) is higher than the bearing ball center, the A face simultaneously with planet axis (7) at a distance of the certain interval distance.
