What structure was usually fixed, when needing cabinet to do idle running, gear can not efficiently separate out, or some point
From structure is complicated, manufacturing cost is higher.
Summary of the invention
The purpose of this utility model is provided between a kind of gear and axis for the above-mentioned problems in the prior art
Separation and the simple separate type gear-driven assembly of structure can be intermeshed.
The purpose of this utility model can be realized by the following technical scheme: a kind of separate type gear-driven assembly, including
Cooperate gear, main shaft and the tooth shaft being arranged, and the gear clearance is matched on main shaft and is connected by key, the gear
Outer teeth can be intermeshed with tooth shaft, the position of medium tooth shaft and main shaft is mutually perpendicular to, which is characterized in that the tooth
It is provided with the inconsistent clamping of both ends of the surface of two angles and gear of a shift fork and shift fork on wheel, is vertically arranged on the shift fork
The adjusting rod of integral structure is provided with the position limiting structure for preventing it from rotating automatically on the adjusting rod.
The principle of this separate type gear-driven assembly are as follows: gear clearance, which is matched on main shaft, realizes sliding, and sliding passes through
Realize that shift fork rotated by adjusting rod in shift fork, the angle of shift fork gear face will be acted on a thrust make gear and
Tooth shaft separation, similarly can be such that gear and tooth shaft engages again, further, in order to after shift fork is adjusted by reversed thrust
It can fix, there is position limiting structure on adjusting rod, wherein position limiting structure also acts as fixed shift fork when gear and tooth shaft engaged transmission
With the effect of gear.
In a kind of above-mentioned separate type gear-driven assembly, one is offered with the joint of gear on the main shaft and is led to
Hole, the both ends of the through-hole are fixed with flat key, and the flat key includes integrated fixing end and limited post, the limit
Column is in interference fit in through-hole, and wherein the length of limited post is the half of through-hole, has and two flat keys on the gear
The keyway matched.By two flat key symmetric designs, it is more firm to make the cooperation of gear and main shaft, and flat key passes through limit
Column is installed in through-hole, and relative to the integral structure of traditional flat key and main shaft, manufacturing process is simpler, facilitates production.
In a kind of above-mentioned separate type gear-driven assembly, the external margin of the fixing end is rounded structure.Circle
The design of corner structure facilitates the installation and sliding of gear.
In a kind of above-mentioned separate type gear-driven assembly, the axially extending formation in a wherein end face for the gear and master
The interconnecting piece of axis cooperation.The sliding amplitude that interconnecting piece can increase gear prevents gear to be detached from slipping with flat key.
Compared with prior art, this separate type gear-driven assembly makes to realize between gear and tooth shaft by the design of shift fork
Separation has the advantages that the simple manufacturing cost of structure is low with engagement.
