Abstract
The utility model relates to a planet gear reduction box for avoiding the skidding of center wheel and planet plate. The reduction box can resolve the skidding problem caused by smaller contact surface of center wheel of knurling gear and center hole of planet plate through non round hole match of center wheel and planet plate, the inner gear(7) is arranged between front end cover(5)and rear end cover(6)on reduction box, the inner gear(7) is connected with output shaft(9) through front end cover(5)located out of the bearing, one side of planet plate(2) is matched with planet gear, the center of which is matched with center wheel on transmission shaft, the feature of non round hole matching of center wheel(1) and planet plate(2) can improve transmission efficiency and prolong service life.
Description
Technical field
The utility model relates to the speed reducer device of field of mechanical technique, is a kind of planetary gear reduction box that can prevent that central gear and planet plate from skidding specifically.
Background technique
At present, planetary gear reduction box structure of the prior art generally adopts central gear annular knurl gear to be connected with planet plate circular hole, when some machinery work transmission, because torsion mainly acts on the central gear, but the surface of contact of the center hole of annular knurl gear on the central gear and planet plate is less, this cooperating structure is easy to skid when transmission, cause power to pass not pass by, transmission efficiency is low, and precision is low, and assembling is difficult, the high deficiency of processing cost but also exist.
As mentioned above, there is following deficiency in prior art: skid easily during transmission, transmission efficiency is low, and assembling difficulty and processing cost are high.
Summary of the invention
The utility model skids when having solved the transmission that prior art exists easily, and transmission efficiency is low, and assembling difficulty and the high problem of processing cost provide a kind of non-circular hole by central gear and planet plate to cooperate the planetary gear reduction box that prevents that them from skidding when transmission.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of planetary gear reduction box, be provided with internal gear between front cover on it and the rear end cover, described internal gear links to each other with output shaft by the front cover outer with being located at bearing, planet plate one side and planetary pinion cooperate, match with central gear on being located at transmission shaft in its center, it is characterized in that described central gear and planet plate non-circular hole cooperate, during work, transmission shaft with twisting force to central gear, central gear passes through the cooperation transmission with the planet plate again, non-circular hole interference fit by central gear and planet plate cooperates easy problem of slip with regard to having solved original circular hole, no matter be single-stage or multistage transmission.And make so original because the annular knurl gear wear that skids and cause, thereby the transmission efficiency that causes indirectly is low, and working life is long etc., and deficiency has also obtained solution, make this cooperation transmission efficiency height, and can not skid the precision height, long service life can reach the effect of permanent use.
As preferably, the exterior edge face of planet plate is circular, and its center is that arc body connects plane body, becomes D shape; Central gear hollow, one end profile is a gear, the other end profile is that arc body connection plane body becomes D shape; The D shape profile of the middle heart shape of planet plate and central gear is suitable; During cooperation, the D shape end interference of central gear being deviate from part is pressed in the D shape hole at planet plate center, when transmission, can central gear and planet plate be skidded like this, because can not resemble original problem of slip when causing torsion big because of the surface of contact of annular knurl gear too small when existing in transmission owing to the contact of plane body because torsion mainly acts on the central gear yet.
As preferably, the center of planet plate is that arc body connects some plane bodies, and some plane body knuckles connect; The profile of central gear is that arc body connects some plane bodies, and some plane body knuckles connect.So also can prevent central gear and planet plate because surface of contact less and skid.
As preferably, the planet plate is provided with 3 the 120 uniform circular holes of degree, and these circular holes cooperate by equipped pin and planet wheel cover.
The utility model is skillfully constructed, and is simple in structure, and make easily and promote, and also the transmission efficiency height, long service life.
