Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically is chatted
State, can be replaced by other equivalent or alternative features with similar purpose.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, the first crankshaft bearing 4, bent axle and the first Cycloidal Wheel are provided between one end of bent axle 11 and gland 6
First eccentric part bearing 5 is installed between 7；Second crankshaft bearing 12 is installed between the bent axle other end and wheel seat 15, bent axle with
Second eccentric part bearing 10 is installed between second Cycloidal Wheel 9.The outer ring of the first eccentric part bearing 5 is connected with the first Cycloidal Wheel 7,
The outer ring of the second eccentric part bearing 10 is connected with the second Cycloidal Wheel 9.Needle roller 8 is evenly distributed in the inner side semicircle orifice of pin wheel housing 1
It is interior.First base bearing 2 is installed between gland 6 and pin wheel housing 1, the second base bearing 16 is installed between wheel seat 15 and pin wheel housing 1.
It is whole to constitute single axle cycloidal-pin wheel engagement transmission mechanism.
