In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a planetary reducer's double bracing planet carrier, includes the planet carrier main part, is equipped with three planet gear mounting groove in the planet carrier main part, and the inboard of three planet gear mounting groove is connected as a whole, a planetary gear is all installed to the inside of planet gear mounting groove, be equipped with front end hole and rear end hole in the planet carrier main part, planetary gear's inside is equipped with the planet round pin axle, and the both ends of planet round pin axle are fixed in front end hole and rear end hole, be interference fit between planet round pin axle and the front end hole, be transition fit between planet round pin axle and the rear end hole, be equipped with the kingpin between planet round pin axle and the planetary gear.
The utility model discloses an adopt interference and transition fit between planet round pin axle and front end hole, the rear end hole for more convenience when planet gear and planet round pin axle are installed need not use specific frock just can accomplish the installation, can not bring materials such as iron fillings into planet gear's inside when planet round pin axle is installed simultaneously, has guaranteed kingpin and planet gear's normal rotation, has the universality of practicality and use.
Preferably, the number of the rolling needles is multiple, and the rolling needles are connected with each other to form a circular ring.
This setting has guaranteed the stability of transmission for the skew can not appear when the planetary gear rotates.
Preferably, a gasket is arranged on each of two sides of the connection between the planetary gear and the planet carrier.
This setting prevents to produce direct contact between planetary gear and the planet carrier, prevents simultaneously that the inside kingpin of planetary gear from roll-off.
Preferably, one end of the planet pin shaft, which is located at the rear end hole, is provided with an elastic check ring, and the elastic check ring is fixed on the planet carrier main body.
This setting gives a spacing effect to planet round pin axle, prevents that the in-process of using from appearing taking off.
Preferably, two ends of the planet carrier main body are respectively provided with a taper hole, and the taper angle of the taper hole is 60 degrees and is matched with the taper angle of the standard tip.
The arrangement is convenient for two top grinders to grind the excircle and the end surface during processing; the shape and position tolerance of the planet carrier main body can be conveniently detected by positioning the two apexes during detection.
The utility model has the advantages that: simple to operate, easy operation need not to use the frock calibration in the process of installation, can not produce iron fillings in the installation, can not influence planetary gear and rotate, and the transmission is stable simultaneously, and easy dismounting has the practicality and the universality of use.
