Gyro-precession type reducer

Abstract

The invention discloses a gyro-precession type reducer. The reducer comprises a machine shell, an input axis and an output axis, wherein the input axis is integrated by two support axis sections at the head end and the tail end and a tilting axis section between the two support axis sections; the support axis section at the head end is rotatably arranged on the machine shell; the support axis section at the tail end is rotatably arranged at the head end of the output axis; axes of the two support axis sections and the axes of the output axis are coaxially arranged, and the axes of the tiltingaxis and the axes extended line of the two support axis sections are on the same plane and intersected; and the two support axis sections are in rotatable assembly with the corresponding machine shell and the output axis through a self-aligning roller bearing. The axes of the tilting axis section of the input axis and the axes of the support axis sections at two ends are on the same plane and intersected, so the reducer facilitates to the alignment of position references and process making so as to improve the production efficiency and reduce errors, and adopts radial jumping load which is generated when the tilting axis section rotates and is endured by the self-aligning roller bearing so as to improve the service life.

Description

technical field [0001] The invention relates to a precession reducer, which belongs to reduction machinery. Background technique [0002] At present, the main development direction of deceleration machinery is large transmission ratio, large load capacity, and small volume. Due to the small number of teeth of the traditional multi-stage involute gear reducer that participates in meshing at the same time, it has a large volume and low load capacity; therefore At the same time, the cycloidal gear meshing transmission technology with a large number of meshing teeth has been gradually applied to the field of reduction machinery, such as the commercially available cycloidal pinwheel reducer, but the cycloidal pinwheel reducer has a rotating arm bearing that bears a lot of force, and the output pin mechanism Easy to wear and relatively low service life. Another example is the Chinese patent No.: ZL982379749, title: a precession reducer disclosed in the utility model manual of the...

Another example is the Chinese patent No.: ZL982379749, title: a precession reducer disclosed in the utility model manual of the precession reducer. This patent document proposes a tapered roller ring gear on a planetary gear and two ends The corresponding design concept of rolling friction meshing between bevel gears to transmit power has not yet constituted a complete technical solution that can be manufactured in the industry. Therefore, it is necessary to propose a precession reducer that meets the needs of industrialization and has market competitiveness.
