Abstract

The invention discloses a kind of door and window bevel type gear gearbox, including casing, also include being pivotally supported at rotary shaft on casing, the driven gear being non-rotatably secured in rotary shaft and the driving gear engaged with driven gear by bearing, the diameter of the driven gear is more than active diameter, the output shaft drive connection of the driving gear and motor, the driven gear and driving gear are bevel type gear.The gearbox can realize the rotating of door and window when power is off by the way of driving gear and driven gear engagement, and can also make motor more stable during driving door and window movement.

Description

A bevel gear gearbox for doors and windows

technical field

The invention relates to the field of door and window transmission, in particular to a bevel gear box for doors and windows.

Background technique

The electric drive part of traditional aluminum alloy doors and windows adopts chain or belt transmission to realize the closing and opening of doors and windows, which cannot work in the case of power failure, low stability and inconvenient maintenance.

Contents of the invention

The main purpose of the present invention is to provide a bevel gear gearbox for doors and windows, which can ensure the normal use of doors and windows in the case of power failure, is convenient for maintenance, and has high stability.

In order to achieve the above purpose, the technical solution adopted by the present invention is: a bevel gear gearbox for doors and windows, including a box body, which is characterized in that it also includes a rotating shaft that is rotatably supported on the box body by a bearing, and is non-rotatably fixed. The driven gear on the rotating shaft and the driving gear meshed with the driven gear, the diameter of the driven gear is larger than the driving diameter, the driving gear is connected with the output shaft of the drive motor, the driven gear and the driving gear All are bevel gears.

Preferably, the driving gear is adjustable along its axis.

Preferably, a motor hole is provided on the box body, and the driving motor passes through the motor hole and is connected to the driving gear for transmission.

Preferably, the rotating shaft has a protruding part protruding from the box, and the protruding part is connected with the transmission device of the door and window.

Preferably, there is a slit extending axially along the rotation axis on the protrusion.

Compared with the prior art, the present invention has the following beneficial effects:

The gearbox uses bevel gears to decelerate. On the one hand, when the power is off, the doors and windows can be reversed. On the other hand, it can also make the drive motor more stable when driving the doors and windows to rotate.

Detailed ways

The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

As shown in Figure 1-3, a bevel gear gearbox for doors and windows includes a box body 1, a rotating shaft 2 rotatably supported on the box body 1 through a bearing 5, and a secondary shaft non-rotatably fixed on the rotating shaft 2 The driving gear 3 and the driving gear 4 meshed with the driven gear 3, the driving gear 4 is connected with the output shaft of the driving motor, specifically, the driving motor is inserted into the driving gear 4 from the motor hole 6 provided on the casing 1 connect.

Both the driven gear 3 and the driving gear 4 adopt bevel gears, which can realize positive and negative rotation on the one hand, and are more stable with respect to chains or belts on the other hand. The transmission ratio of the driving gear 4 and the driven gear 3 is 1:2.

In order to be able to compensate for the wear of the gear, the driven gear 3 is set to be able to move axially relative to its axis. When the gear wears, the compensation can be realized by adjusting the position of the driven gear 3 in its axial direction, ensuring Forward and reverse stability.

One end of the rotating shaft 5 has a protruding part 8 protruding from the box body 1, and a notch 81 extending axially along the rotating shaft 2 is provided on the protruding part 8, through which the notch 81 is conveniently connected with the transmission device of the door and window.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description are only the principles of the present invention. Variations and improvements, which fall within the scope of the claimed invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
