RV speed reducer based on CTC (Centralized Traffic Control) circular arc and single circular arc few tooth difference planetary transmission
A technology of planetary and reducer with less tooth difference, applied in the direction of gear transmission, transmission, transmission parts, etc., can solve the problem that cannot meet the requirements of severe working conditions of aerospace servo mechanism, the coefficient of gear tooth coincidence is small, and the difficulty of miniaturization is increased. Large and other problems, to avoid the possibility of interference, the contact area of the gear teeth is large, and the structure is compact.

[0019] The present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0020] Such as figure 1 , figure 2 with image 3 As shown, the present invention provides an RV reducer based on CTC circular arc and single circular arc and small tooth difference planetary transmission, including a fixed seat 1, an input end flange 2, an eccentric shaft 3, a bearing baffle 4, and a planetary gear 5. Gear shaft 6, first input end positioning pin 7, external gear 8, output end flange 9, second input end positioning pin 10, spring washer 11, bearing retaining ring 12, needle bearing 13, eccentric shaft support bearing 14. Flange support bearing 15, hexagon socket head screw 16.
[0021] Such as figure 2 As shown, the eccentric shaft 3 is two shafts distributed up and down. Two external gears 8 are sleeved on the two eccentric shafts 3. The phase angles of the two external gears 8 are different by 180°. Each external gear 8 is sleeved on the b...
