Abstract
The utility model discloses a double-stage driving servo planetary reducer with an excellent fixing effect. The double-stage driving servo planetary reducer comprises an input flange and an internally toothed annulus connected to the input flange through a screw, wherein an input shaft is arranged in the input flange through bearings of the input shaft; an output shaft is arranged in the internally toothed annulus through bearings of the internally toothed annulus; the input shaft is connected to a primary sun gear mutually matched with a primary planet gear; the primary planet gear is connected to a primary planet carrier connected to a secondary sun gear; the secondary sun gear is matched with a secondary planet gear connected to a secondary planet carrier; the secondary planet carrier is connected to the output shaft; the primary planet gear and the secondary planet gear are respectively arranged on a needle roller through bearings of the planetary gears in a rotating manner; and the input shaft is connected to a motor shaft of a servo motor through an inner hexagon screw. The double-stage driving servo planetary reducer has the advantages of small size, high processing precision, low noise, low energy consumption and good transmission effect as the input shaft and the motor shaft are connected through the inner hexagon screw.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to the servo planetary speed reducer of a kind of two-stage transmission.
Background technique
Planetary pinion in the planetary speed reducer is except can be as fixed axis gear rotating round oneself rotatingshaft, their rotatingshaft is also along with the axis of planet carrier around other gear (sun gear) rotates, rotation around own axis becomes rotation, rotation around other Gear axis is called revolution, planet just as in the solar system hence obtains one's name.Is connected by key between input shaft and the motor shaft in the existing planetary speed reducer, is rigid connection, machining accuracy is bad, and noise is big, the energy consumption of generating heat height, and the transmission effect is bad.
The model utility content
Technical problem to be solved in the utility model is: the servo planetary speed reducer of two-stage transmission that a kind of good fixing effect is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the servo planetary speed reducer of two-stage transmission, comprise: input flange, the ring gear that is connected with input flange by screw, in input flange, be provided with input shaft by bearing of input shaft, in ring gear, be arranged on output shaft by the ring gear bearing, described input shaft is connected with the one-level sun gear, one-level sun gear and one-level planet wheel cooperatively interact, the one-level planet wheel is connected with primary planet carrier, primary planet carrier is connected with the secondary sun gear, secondary sun gear and secondary planet wheel cooperatively interact, the secondary planet wheel is connected with the secondary planet frame, the secondary planet frame is connected with described output shaft, described one-level planet wheel and secondary planet wheel rotate by planet wheel bearing respectively and are arranged on the needle roller, and described input shaft is connected with the motor shaft of actuating motor by socket head screw.
The utility model has the advantages that: be connected by socket head screw between the servo planetary speed reducer of above-mentioned two-stage transmission, input shaft and motor shaft, good fixing effect, body is less, the machining accuracy height, noise is little, and energy consumption is low, and transmission is effective.
