Abstract
The invention discloses a duplex transmission gear of a window opener. The duplex transmission gear of the window opener comprises a superposed tooth profile end face (1), a mounting shaft hole (2), a superposed tooth meshing face (3), a limiting screw (4), a gear meshing reference circle (5) and a gear body (6). The superposed tooth profile end face (1) of the duplex gear is superposed and assembled with the superposed tooth meshing face (3). The mounting shaft hole (2), the superposed tooth profile end face (1) and the superposed tooth meshing face (3) are assembled coaxially. In the assembling process of the gear body (6), the superposed tooth profile end face (1) is provided with an axial limiting mechanism.
Description
Technical field
The present invention relates to a kind of window opener, specifically a kind of window opener duplex transmission gear.
Background technique
Window control has another name called window opener.Adopted widely the control at Smart Home window, the places such as the ventilation smoke exhaust of large buildings place window.The core position gearbox of window opener is that window opener is able to the guarantee of running smoothly.But owing to being subject to the uneven puzzlement of domestic overall machining level of processing and assembly technology, making the window opener gearbox function admirable of every production and being consistent is the problem that each producer faces.The core component of gearbox is the assembling of gear, and tradition is by the trim designs theory of axis hole tolerance fit mode, cannot meet product performance truly consistent.And through running after a while, easily there is the problem that gear " interlock " is interrupted or dally.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of window opener duplex transmission gear, can, guaranteeing, under the prerequisite of assembly precision, to improve efficiency of assembling, utilize simple moulds of industrial equipment, can complete assembling work.
To achieve these goals, the technical solution used in the present invention is: a kind of window opener duplex transmission gear, comprises stack profile of tooth end face, installation axle hole, stack tooth Surface of action, stop screw, gear engagement standard pitch circle, gear body; The assembling that superposes of the stack gear face of duplicate gear and stack tooth Surface of action, base station and basal plane secure fit in assembling; Installation axle hole, stack profile of tooth end face coaxially assemble with stack tooth Surface of action.
The torque that in chain type window opener, worm and gear outputs to rear class utilizes this duplicate gear overlay model assembling.
This duplex gearbox gear is with position-limit mechanism reserved function.
Compared with existing chain type window opener gearbox gear: the present invention arranges duplex stack gear in new-type window opener gearbox.Adopt the gearbox gear of this kind of new-type window opener, in assembly process without transmission that the fit tolerance of axis hole is brought up to very high grade can complete more accurate gear torque.The reserved location that is positioned at the stop screw above gear body is Emergency braking or the control of stroke intelligence of window opener chain output.The assembling of this gear without and the assurance of outer moulds of industrial equipment by the penetrating of central shaft, guarantees that the laminating intensity of one group of gear stack tooth Surface of action can meet the transmission of coaxial and moment of torsion by one group of gear.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2, a kind of window opener duplex transmission gear, comprises stack profile of tooth end face 1, installation axle hole 2, stack tooth Surface of action 3, stop screw 4, gear engagement standard pitch circle 5, gear body 6; The assembling that superposes of the stack gear face 1 of duplicate gear and stack tooth Surface of action 3, base station and basal plane secure fit in assembling; Installation axle hole 2, stack profile of tooth end face 1 and the 3 coaxially assemblings of stack tooth Surface of action; The gear body 6 adopting is carrying out in duplex assembly process, and stack profile of tooth end face 1 needs secure fit and axial limiting mechanism to need external structure to provide.
When needs are assemblied in chain type window opener inside by novel basis window opener duplex transmission gear, first stack profile of tooth end face 1, installation axle hole 2, stack tooth Surface of action 3 are made a distinction; Installation axle hole 2 is used for installation shaft, but will note the quality of fit in gear body 6 holes.
Further, if use this gear on same one-level output shaft, to confirm the best fit tolerance of nest.
Assembling mode is divided into two states:
Duplex assembling use state:
The assembling that superposes of the stack gear face 1 of duplicate gear and stack tooth Surface of action 3, base station and basal plane secure fit in assembling; Installation axle hole 2, stack profile of tooth end face 1 and the 3 coaxially assemblings of stack tooth Surface of action.
State is used in multistage assembling:
The gear that the multistage assembling of using at same axis hole is used, except gear one side at two ends is with this structure, being positioned at inner gear all needs bilateral with this structure.In assembly process, rationally confirm thickness and the optimal engagement tolerance of assembling gear.
The invention is not restricted to the to superpose sector structure of tooth Surface of action 3, cross recess, other concavo-convex cooperatively interact and structure that coaxially mechanical torque is transmitted in assembling also belongs to protection scope of the present invention.
Claims (2)
1. a window opener duplex transmission gear, comprise stack profile of tooth end face (1), installation axle hole (2), stack tooth Surface of action (3), stop screw (4), gear engagement standard pitch circle (5), gear body (6), it is characterized in that, the stack gear face (1) of duplicate gear and stack tooth Surface of action (3) assembling that superposes, base station and basal plane secure fit in assembling; Installation axle hole (2), stack profile of tooth end face (1) coaxially assemble with stack tooth Surface of action (3); The gear body (6) adopting is carrying out in duplex assembly process, and stack profile of tooth end face (1) needs secure fit and axial limiting mechanism to need external structure to provide.
2. a kind of window opener duplex transmission gear according to claim 1, is characterized in that, stack profile of tooth end face (1), stack tooth Surface of action (3) stack assembling conduction rotary torsion.
