Title:
ECCENTRIC SWINGING TYPE GEAR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/233345
Kind Code:
A1
Abstract:
An eccentric swinging type gear apparatus, wherein the diameter of needle tooth pin holes is greater than the diameter of needle teeth, and the diameter of a center distribution circle of the needle tooth pin holes is smaller than the diameter of a center distribution circle of the needle teeth so that, on one hand, the lubrication of the needle teeth is facilitated, and on the other hand, the grinding of the needle tooth pin holes is also facilitated, and thus the machining efficiency is improved. The eccentric swinging type gear apparatus comprises: a needle tooth shell (1), the inner circumference of the needle tooth shell (1) being provided with the needle tooth pin holes, and the needle teeth (18) being disposed in the needle tooth pin holes; a planetary carrier (3) mounted on the needle tooth shell (1) in a freely rotatable manner; a pair of main bearings (4, 17), each comprising a roller and an annular body, the annular body being used for supporting the roller, and the pair of main bearings being provided between the outer circumference of the planetary carrier (3) and the inner circumference of the needle tooth shell (1); a crankshaft (10) mounted on the planetary carrier (3) in a freely rotatable manner; and cycloidal gears (15, 16) having teeth engaged with the needle teeth (18), mounted on a crank portion of the crankshaft (10) and disposed between the pair of main bearings (4, 17). The crankshaft (10) rotates to make the cycloidal gears (15, and 16) swing eccentrically, and rotary output is obtained from the needle tooth shell (1) or the planetary carrier (3).
