Description of the drawings
Fig. 1 is a kind of crank connecting link assembly for exempting from oil filter of the utility model；
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of crank connecting link assembly for exempting from oil filter as shown in Fig. 1 to 2, including：Left crank 3, right crank 6, song
Handle pin 7, connecting rod 5, disc 2；The major part of connecting rod 5, left crank 3, right crank 6 are connected by crank-pin 7, and connecting rod 5 is located at left song
6 between handle 3 and right crank；Needle bearing 4 is equipped between the major part of connecting rod 5 and crank-pin 7；Left crank 3 is close to axle portion side
Large end face has annular groove, and 2 location and installation of disc has the in the annular groove, and between disc 2 and crank-pin 7
One gap 20；Left crank 3 has grease channel, which is communicated in the first gap 20；Crank-pin 7 have blind hole and with
First gap 20 connects；7 middle part of crank-pin has the oilhole of radially setting, one end connection needle bearing 4, other end connection institute
State blind hole.
A kind of crank connecting link assembly for exempting from oil filter as shown in Figures 1 and 2, further includes deep groove ball bearing 1, timing
Sprocket wheel 8, deep groove ball bearing 1 are installed on first axle cervical part of esophagus of the left crank 3 close to big end, and left end is set by 8 right end of timing sprocket
The flange put is limited, and in addition 2 left end of disc is limited by 1 inner ring of deep groove ball bearing, and disc 2 and deep-groove ball
