Abstract
The utility model discloses a stepless speed changing planet speed changer which comprises a central gear (3), a first planet gear (4), a planet carrier (8), a fixed ring (5) and a moving ring (6), wherein the first planet gear (4) is movably contacted with the central gear (3); a first rotating shaft (7) of the first planet gear (4) is connected with the planet carrier (8); and the fixed ring (5) and the moving ring (6) are respectively contacted with a gear surface of the first planet gear (4). The stepless speed changing planet speed changer is characterized in that a second output shaft (9) of the planet carrier (8) is connected with a sun gear (12) which is meshed with a second planet gear (11); and the second planet gear (11) is connected with an output shaft (13) by a rotating arm (14); and the sun gear (12) and the second planet gear (11) are installed inside a gear ring (10). In the planet speed reducer, a second output shaft of the planet carrier is further connected with a speed reducing mechanism formed by the sun gear and the second planet gear, so that the transmission ratio of the speed reducer can be increased, the carrying capacity is greatly improved, and the performance of the speed reducer is improved.
Description
Technical field
The utility model relates to a kind of retarder, particularly be the stepless change retarder.
Background technique
At present, the stepless change retarder uses more extensive, its basic structure is to have planet wheel, central gear and planet carrier to constitute, its planet wheel moves in turn with the center and contacts, also having of contacting with planet wheel decided to encircle and rotating ring, side at central gear is provided with belleville spring, when belleville spring compresses, the rotating ring of planet wheel one side is moved axially, the working surface of central gear and planet wheel is pressed against each other, and after rotating ring moves axially, planet wheel is moved radially, after planet wheel moved, the centre distance of rotating shaft and planet carrier changed on the planet wheel, thereby changed the rotating speed of planet carrier.The speed changer of this structure, its velocity ratio and bearing capacity are relatively poor; Simultaneously, because the contact surface of deciding ring, rotating ring and central gear is the plane, thereby decides ring and belong to line with rotating ring with the taper wheel face and contact, the working efficiency of speed changer can reduce like this.
The model utility content
In view of the deficiency that background technique exists, the technical problems to be solved in the utility model provides a kind of velocity ratio and the stronger stepless speed-changing gear retarder of bearing capacity.
For this reason, the utility model is realized by the following technical solutions: a kind of stepless change planetary transmission, comprise central gear, first planet wheel, planet carrier, fixed ring and rotating ring, described first planet wheel moves in turn with the center and contacts, first rotatingshaft of described first planet wheel is connected with described planet carrier, described fixed ring contacts with the wheel face of first planet wheel respectively with rotating ring, second output shaft that it is characterized in that described planet carrier connects sun gear, described sun gear and the engagement of second planet wheel, described second planet wheel connects output shaft by pivoted arm, and the described sun gear and second planet wheel are installed in the gear ring; The described contact surface of deciding ring, rotating ring and central gear and first planet wheel is a curved surface.
In the utility model, connect the reducing gear that the sun gear and second planet wheel constitute again on second output shaft of planet carrier, make the velocity ratio of retarder obtain enlarging, bearing capacity is greatly improved, and has improved the performance of retarder.After the contact surface of deciding ring, rotating ring and central gear become curved surface from the plane, improve the working efficiency of retarder, avoided the interference of surface of contact physical dimension simultaneously.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this stepless speed-changing gear retarder, comprise central gear 3, first planet wheel 4, planet carrier 8, surely encircle 5, rotating ring 6, described first planet wheel 4 and central gear 3 moving contacts, first rotatingshaft 7 of described first planet wheel 4 is connected with described planet carrier 8, describedly encircle 5 surely and contact with the wheel face of first planet wheel 4 respectively with rotating ring 6, side at central gear 3 is provided with belleville spring 2, second output shaft 9 of described planet carrier 8 connects sun gear 12, described sun gear 12 and 11 engagements of second planet wheel, described second planet wheel 11 connects output shaft 13 by pivoted arm 14, and the described sun gear 12 and second planet wheel 11 are installed in the gear ring 10; Describedly encircle 5 surely, the surface of contact of rotating ring 6 and the central gear 3 and first planet wheel 4 is curved surface.When input shaft 1 input power, drive central gear 3 and rotate, central gear 3 passes through the frictional force transmission with first planet wheel 4 of both sides.When the belleville spring 2 of central gear 3 one sides pressurizes, make rotating ring 6 move axially, make central gear 3 and both working surfaces of first planet wheel 4 be pressed against each other simultaneously, because encircling 5 surely maintains static, moving axially of rotating ring 6, realize moving radially of first planet wheel 4, first planet wheel footpath 4 is after moving, first output shaft 7 on it just changes with the center of planet carrier 8, the rotating speed of the planet carrier 8 that changes so, after second output shaft, 9 outputs on the planet carrier 8, again by sun gear 12, the transmission of second planet wheel 11 and gear ring 10 outputs to output shaft 13, has so just reached the purpose of gearing down, the retarder of this structure, its velocity ratio range of choice is bigger, and its bearing capacity height, has improved the working efficiency of retarder simultaneously.
Claims (2)
1. stepless change planetary transmission, comprise central gear (3), first planet wheel (4), planet carrier (8), fixed ring (5) and rotating ring (6), described first planet wheel (4) contacts with central gear (3) is moving, first rotatingshaft (7) of described first planet wheel (4) is connected with described planet carrier (8), described fixed ring (5) contacts with the wheel face of first planet wheel (4) respectively with rotating ring (6), second output shaft (9) that it is characterized in that described planet carrier (8) connects sun gear (12), described sun gear (12) and second planet wheel (11) engagement, described second planet wheel (11) connects output shaft (13) by pivoted arm (14), and described sun gear (12) and second planet wheel (11) are installed in the gear ring (10).
