Description
Technical field
The present invention relates to a kind of variable number of teeth external gears, belong to gear structure technical field.
Background technology
In machinery industry, power transmission is very important a ring, and gear drive be important transmission mechanism it
One, have transmission ratio more accurate, it is efficient, it is compact-sized, the advantages of reliable operation, long lifespan.
Currently, during gear box designs, when the speed ratio of gear-box changes, it need to quickly change the tooth of gear
Number, and the gear of machined completion also becomes waste product before, causes the waste of resource, is badly in need of solving as a result,.
Invention content
It is an object of the invention in view of the above-mentioned problems, a kind of variable number of teeth external gear is proposed, to solve existing gear
The needs that change by speed ratio of case design development phase, the problem of leading to the wasting of resources.
The purpose of the present invention is be achieved through the following technical solutions：
A kind of variable number of teeth external gear, is made of, institute external gear mounting base, bidentate mounting blocks, monodentate mounting blocks, mounting blocks block piece
The center for stating external gear mounting base is provided with axis hole, and external gear mounting base outer ring has mounting blocks guide groove, mounting blocks guide groove side to have
Guide groove fans ring notch, and it is tapped blind hole that guide groove, which is fanned on the left of ring notch, and it is through-hole that guide groove, which is fanned on the right side of ring notch, the bidentate installation
Block, monodentate mounting blocks enter mounting blocks guide groove by guide groove fan ring notch and are connected with external gear mounting base, bidentate installation
The outer surface setting of block is there are two the gear teeth, and the outer surface settings of the monodentate mounting blocks is there are one the gear teeth, and monodentate mounting blocks
Middle part has a through-hole, the guide groove that the mounting blocks block piece is mounted on guide groove side by bolt to fan ring indentation, there.
As a preferred embodiment of the present invention, the notch of mounting blocks guide groove side is 43 ° of fan ring notches.
As a preferred embodiment of the present invention, the inner surface of the bidentate mounting blocks and monodentate mounting blocks is provided with type
Shape pedestal.
Beneficial effects of the present invention are that a kind of variable number of teeth external gear is easily changed number of gear teeth, by using this
Kind structure, can quickly change the number of teeth to meet the needs of gear box designs development phase speed ratio variation, save production cost.
