Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As shown in Figures 1 to 6, the transmission device 1 for being used for light hoisting gear jacking mechanical arm includes a transmission bar assembly 2
With a bearing assembly 3, the bearing assembly 3 includes an axle sleeve 5, one shaft-cup 4 of the top of axle sleeve 5 installation, the inside of axle sleeve 5 installation one
