Embodiment

[0017] Such as figure 1 As shown, a compact planetary transmission structure includes a planetary gear 5 and a sun gear 2. The planetary gear 5 is axially connected to the planet carrier 6 of the current stage, and the sun gear 2 is installed on the planet carrier 6 of the current stage. The end of the wheel 2 away from the planet carrier 6 of the current stage is connected with the planet carrier 3 of the front stage.

[0018] In this embodiment, the planetary gear 5 is connected to the current-stage planetary carrier 6 through a planetary shaft 7 . The planetary gear 5 is keyed to the planetary shaft 7 . The planetary gear 6 of the current stage is connected to the sun gear 2 through the top block 8 of the current stage. The sun gear 2 is connected to the front-stage planet carrier 3 through the front-stage top block 1 . A shaft retaining ring 4 is arranged between the sun gear 2 and the front stage planet carrier 3 .

[0019] In consideration of practical use, the shaft...

Abstract

The invention discloses a compact planetary transmission structure. The compact planetary transmission structure comprises a planet gear and a sun gear, and is characterized in that the planet gear is in shaft connection with a current-stage planet carrier, the sun gear is mounted on the current-stage planet carrier, and the end of the sun gear, far away from the planet carrier, is connected with a preceding-stage planet carrier. According to the invention, as the sun gear is connected with the preceding-stage planet carrier and is simultaneously in meshed transmission with the planet gear for deceleration, a shaft check ring is used for positioning the planet carrier, and the inner end part of the sun gear is subject to carburizing and quenching, the rigidity is improved, the gap of the preceding-stage planet carrier is ensured, and normal meshing is guaranteed. The sun gear saves time, improves the efficiency, and saves the structure space of a speed reducer, as well as the processing time and cost.

Description

technical field [0001] The invention relates to a compact planetary transmission structure. Background technique [0002] At present, when most planetary reducers on the market transmit power, the sun gear has two teeth, one drum-shaped tooth is connected to the previous planetary structure, and an involute tooth is meshed with the planetary gear through an inner gear sleeve. slow down. This structure has many internal parts and a large space, especially the sun gear, which requires a certain undercut distance. In addition, there are two tooth shapes, which lead to high processing costs and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects and provide a compact planetary transmission structure that saves time, improves efficiency, saves the structural space of the reducer, saves processing time and cost. [0004] In order to solve the above problems, the technical solution adopt...
