Abstract
The utility model discloses a kind of thrust bearing of electric shrub and hedge trimmer, including the motor output shaft and ball-screw being connected, bearing block is arranged with motor output shaft, drawn cup needle roller bearing is provided between bearing block and motor output shaft, the bottom of bearing block is provided with plane needle bearing, Plane Ball bearing is provided with the top of bearing block, Plane Ball bearing bottom is set on motor output shaft, and Plane Ball its top is set on ball-screw；Advantage is that the setting of ball bearing increases overall shearing dynamics, reduces caloric value, while alleviate shearing sound.
Description
Technical field
A kind of electric shrub and hedge trimmer is the utility model is related to, more particularly, to a kind of thrust bearing of electric shrub and hedge trimmer.
Background technology
Electric shrub and hedge trimmer is the common tool for trimming various branches in gardens.In Patent No. 201510072074.0
State's patent of invention discloses a kind of electric pruner, and it includes scissors body, and the front end of the scissors body is provided with activity even
The cutting blade and ledger-plate connect；The tail end of the scissors body is connected with shell；It is provided with the shell and promotes the cutting blade
The drive device of operation；The bottom of the shell is provided with trigger；The drive device includes motor, epicyclic gearbox, gear train
And power module；Described motor one end is electrically connected with the power module, and the other end is mutually driven with the epicyclic gearbox；It is described
Epicyclic gearbox is mutually driven with the gear train, using electric pruner of the present invention, has that transmission energy is big, noise
It is small, the characteristics of blade is readily replaceable, and service life is high.But the thrust bearing of such electric pruner uses needle roller axle mostly
Hold, when wait the branch pruned it is thicker or it is more difficult cut when, it may appear that shearing dynamics it is inadequate, the problem of easily heating.
The content of the invention
Technical problem to be solved in the utility model is to provide the electric shrub and hedge trimmer that a kind of shearing dynamics is good, heating is few
Thrust bearing.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of thrust bearing of electric shrub and hedge trimmer
