Abstract
The utility model discloses a wind power planetary gear support device which comprises a planetary frame (1), a planetary shaft (2), a planetary gear (5), an inner ring gear (8) and a sun gear (9), wherein both ends of the planetary shaft (2) extend to the mounting inner hole of the planetary frame (1), the planetary gear (5) is supported on the planetary shaft (2) through a bearing, the planetary gear (5) is meshed with the inner ring gear (8) through the sun gear (9), the planetary gear (5) is supported on the planetary shaft (2) through two symmetrically-distributed left and right conical bearings (3,7), and the left and right conical bearings (3,7) are mounted back to back. As the wind power planetary gear support device adopts two conical bearings without outer rings and mounted back to back to support the planetary gear, on one hand, the bearing space size is reduced, and the structure size limitation of the planetary gear is solved; on the other hand, the support rigidity of the planetary shaft is effectively improved, so the wind power planetary gear support device has the advantages of ingenious design, simple structure, easy implementation, good reliability and long service life.
Description
Technical field
The utility model belongs to the planetary pinion technical field, specifically, relates in particular to a kind of planetary no outer ring of wind-powered electricity generation cone bearing support device that is used for.
Background technique
Epicyclic train generally includes planet carrier, planet axis, planet wheel, ring gear and sun gear, wherein, the central position of ring gear is provided with sun gear, between ring gear and sun gear, the annular space is arranged, planet wheel is in the gap between sun gear and the ring gear, to being meshed with sun gear, extroversion is meshed with ring gear, and can make circular movement in described gap in the planet wheel.Described planet wheel is bearing on the planet axis by bearing, and planet axis is installed in the planet carrier.At present, the planetary support device of wind-powered electricity generation adopts full roller cylindrical bearings, because of its no retainer, has the roller damage risk of skidding, and because of this bearing size is bigger, and limited the physical dimension of planet wheel; In addition, adopt at planetary pinion under the situation of helical teeth, because the existence of its upset tilting moment produces the bearing roller bearing area and changes, bearing will reduce actual life greatly.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of wind-powered electricity generation planetary pinion support device that can effectively improve the planet axis rigidity of support.
The technical solution of the utility model is as follows: a kind of wind-powered electricity generation planetary pinion support device, comprise planet carrier, planet axis, planet wheel, ring gear and sun gear, wherein the two ends of planet axis are stretched in the installation endoporus of planet carrier, on planet axis, support planet wheel by bearing, this planet wheel is by sun gear and ring gear engagement, its key is: described planet wheel by about the cone bearing of two symmetric arrangement be supported on the planet axis, and left and right cone bearing adopts back-to-back installation.
The utility model changes the full roller cylindrical bearing between planet axis and the planet wheel cone bearing of two back-to-back installations into, when being convenient to Bearing Installation, has effectively improved the rigidity of support of planet axis, and has eliminated the risk of skidding and damaging.
Above-mentioned left and right cone bearing constitutes by inner ring and roller, and wherein inner ring is solidly set on the planet axis, forms conical raceway between inner ring and planet wheel, and described roller is installed in this taper shape raceway.Two cone bearings do not have the outer ring, and the planetary pinion inner hole surface has reduced the bearing space size like this as the outer ring of cone bearing, have solved the physical dimension restriction of planet wheel.
Between above-mentioned left cone bearing and right cone bearing spacer ring is installed, this spacer ring is set on the planet axis.Spacer ring has increased the bearing area of bearing roller, has further improved the rigidity of support of planet axis.
Between above-mentioned planet carrier and right cone bearing spacer is housed, spacer is set on the planet axis.Can control the inside play of two cone bearings by the thickness of regulating spacer, guarantee two cone bearing work normally and efficiently.
Beneficial effect: the utility model no outer ring bevel gear by two back-to-back installations on planet axis is supported planet wheel, has reduced the bearing space size on the one hand, has solved the physical dimension restriction of planet wheel; On the other hand, effectively improve the rigidity of support of planet axis, had characteristics such as design is ingenious, simple in structure, enforcement is easy, good reliability, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of parts such as planet carrier 1, planet axis 2, left cone bearing 3, spacer ring 4, planet wheel 5, spacer 6, right cone bearing 7, ring gear 8 and sun gears 9, wherein planet axis 2 is positioned at planet carrier 1, the two ends of planet axis 2 are stretched in the installation endoporus of planet carrier 1, cone bearing 3, the 7 supporting planet wheels of installing by left and right two back-to-back symmetries on planet axis 25, this planet wheel 5 is by equally distributed sun gear 9 on the circumference and ring gear 8 engagements.Described left and right cone bearing 3,7 constitutes by inner ring and roller, and wherein inner ring is solidly set on the planet axis 2, forms conical raceway between inner ring and planet wheel 5, and described roller is installed in this taper shape raceway.Left and right cone bearing 3,7 adopts the design of no outer ring, and the inner hole surface of planet wheel 5 is as the outer ring of cone bearing, and this structure has reduced the bearing space size, has solved the physical dimension restriction of planet wheel.Simultaneously, adopt carburizing and quenching to handle to planet wheel 5 endoporus, to improve its hardness, wear resistance and fatigue strength.
As can be known from Fig. 1, between left cone bearing 3 and right cone bearing 7 spacer ring 4 is installed, this spacer ring 4 is set on the planet axis 2, and spacer ring 4 has increased the bearing area of bearing roller, has further improved the rigidity of support of planet axis.Between described planet carrier 1 and right cone bearing 7 spacer 6 is housed, spacer 6 is set on the planet axis 2.Thickness by regulating spacer 6 is controlled to be negative value with the inside play of left cone bearing 3 and right cone bearing 7, and so left cone bearing 3 just can be resisted the upset tilting moment that is produced when planet wheel 5 meshes with ring gear 8 and sun gear 9 well with right cone bearing 7.
