Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vertical transmission converting devices for porcelain knob breaker, originally
Inventive structure is simple, transmission performance is reliable, high mechanical strength, power loss is small, economic cost is low, is suitable for different voltages etc.
Grade is particularly suitable for super-pressure, in extra-high voltage porcelain knob breaker switchgear.
In order to solve the above problem, the specific technical solution of the present invention is as follows: a kind of vertical biography for porcelain knob breaker
Turn changing device, shell are symmetrical structure, and the link mechanism for swinging connection, the knot of each link mechanism are symmetrically arranged in shell
Structure are as follows: the connecting lever group that two angles are 90 ° is sleeved on transmission shaft excircle, and angle direction is upward, and two opposite connecting lever I, which are rotated, to be connected
Horizontal conveyor connecting rod is connect, horizontal conveyor connecting rod extends to hull outside, and two opposite connecting lever II are rotatablely connected vertical kinematic link, erect
Direct-transmission connecting rod lower end is hingedly connected with connector.Connecting lever is connect with horizontal conveyor connecting rod by pivot pin, ensure that divide-shut brake is driven
The mechanical strength of pin hole position in the process.
The shell is equipped with half-circle locating aperture about center line symmetrical end face, and half-circle locating aperture and transmission shaft are logical
Cross oilless bushing connection.Transmission shaft 9 is connect by axle sleeve 7 with shell 5, and inner ring is matched with axis, and is revolved together with transmission shaft 9
Turn, outer ring matches with mechanism case and plays a supportive role.
The connecting lever I is connect by pin shaft with horizontal conveyor link rotatable, and the connecting lever II is by pin shaft and vertically
Kinematic link rotation connection.
Vertical kinematic link in the symmetrical link mechanism is located at connector two sides, coaxially connected with connector.
The connecting lever I is connect with connecting lever II with transmission shaft using involute spline.
The vertical kinematic link and horizontal plane.
Bring of the present invention has the beneficial effect that angle is 90 ° between two linking arm of connecting lever, can both make to erect to greatest extent
Histogram drives horizontal direction component to move to moving component, and can guarantee that kinematic link is unlikely to too long, to save mechanism
The space of cabinet；Connecting lever is coupled with transmission shaft using involute spline, since the number of teeth is more and uniform force, therefore bearing capacity
Higher, spline is shallow, and root stress collection is medium and small, lighter to the strength reduction of transmission shaft and connecting lever, while also can guarantee good
To neutral and guiding performance.
