Definitions

  • the invention is a cycloidal pinwheel reducer which is universal or special on mechanical equipment.
  • the input and output are concentric, and the cycloid wheel rotates and revolves.
  • the output mechanism Due to the limitation of the output mechanism, it is not possible to choose a large model for the swing arm bearing, which is also a weak link of the cycloidal pinwheel reducer.
  • the object of the present invention is to provide a cycloid pinwheel reducer with no output mechanism.
  • the reducer has fewer parts, no output mechanism, and a large-size bearing can also be selected.
  • the technical scheme of the present invention is characterized in that the basic component is composed of two pieces of cycloid wheel, a pin wheel, two rotary arm bearings, a double eccentric input shaft and a box body.
  • the swing arm bearing is not concentric with the cycloid wheel, and the input shaft is not concentric with the needle wheel.
  • the power source drives the input shaft to rotate, which causes the two pieces of cycloid wheel to move in parallel, and the needle wheel rotates and outputs.
  • Figure 1 is a sectional view of the basic structure of a cycloid pinwheel reducer with no output mechanism.
  • Fig. 2 is a sectional view taken along line A-A in Fig. 1
  • Fig. 3 is a structural diagram of a two-piece cycloid pin wheel mounted with a uniform load shaft.
  • Fig. 4 is a sectional view taken along line B-B in Fig. 3.
  • two slewing wheels 1 with a phase of 180 ° are equipped with two slewing ring bearings 2.
  • the center of the slewing ring bearing 2 cannot coincide with the center of the slewing ring 1.
  • the slewing ring bearing 2 is provided with a double eccentric input shaft 3
  • the input shaft 3 and the pin wheel 4 are supported on the body 5 by bearings, and the centers of the input shaft 3 and the pin wheel 4 cannot be coincident, that is, they cannot be concentric, and concentric deceleration cannot be established, which belongs to parallel axis rotation and does not belong to coaxial rotation.
  • the transmission principle is that the power source drives the input shaft 3 to rotate and is transmitted to the cycloidal wheel 1 through the swing arm bearing 2. Since the input shaft 3 is not concentric with the needle wheel 4 and the cycloidal wheel 1, the two-piece cycloidal wheel 1 cannot rotate, only It can revolve, that is, the cycloid wheel 1 moves in parallel, and the needle wheel 4 rotates to output at low speed. The input and output directions are the same. It is a positive mechanism.
  • high-power transmission generally adopts compound tooth profile. This tooth profile has a large backlash.
  • a load-sharing shaft 6 can be installed between the two cycloid wheels.
  • the load sharing shaft 6 does not contact the box body, and it can ensure that the two pieces of cycloid wheels are loaded and transmitted.
  • the basic structure of the present invention shown in FIG. 1 is that the input shaft shaft end can be added with a fixed-shaft gear train to form a combined form.
  • a single stage can be connected in series with multiple stages.
  • the body can be made into a vertical and horizontal type. Box for easy disassembly and maintenance.
  • Cycloidal pinwheel reducer without output mechanism, because the output shaft and input shaft are not concentric, the cycloidal pinwheel reducer eliminates the output mechanism, which has the advantages of fewer parts, easy processing, and enhanced bearing capacity of the swing arm bearing. .

Abstract

Cette invention concerne une unité d'engrenages réducteurs de type épicycloïde qui comprend deux engrenages courbes épicycloïdes, une roue annulaire avec des broches, ainsi qu'un arbre d'entrée qui est excentré par rapport à l'arbre de sortie. Cette invention se caractérise en ce que l'on peut se passer des éléments de sortie spécifiques qui sont utilisés en l'état actuel de la technique, et en ce que l'utilisation d'un palier central de grande taille permet d'obtenir de nombreux avantages comme un nombre de pièces réduit, des exigences moindres quant à la précision d'usinage, ainsi qu'un carter de type horizontal pour cette unité qui peut se partager en une partie haut et une partie bas.
