Description

Technical Field

[0001] This utility model relates to the field of window openers, and in particular to a fire-fighting electric window opener for a natural fire-fighting smoke exhaust window system. Background Technology

[0002] Currently, the planetary reduction mechanisms commonly used in the market are all open-type internal, with the planetary gear fixed shaft rotating at a single head. During operation, they have poor stability, high noise, and small assembled parts that are not easy to operate. Summary of the Invention

[0003] The purpose of this invention is to improve stability during transmission, reduce operating noise, extend product lifespan, and facilitate product assembly and production.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: Our product uses a ball cage planetary gear unit (2) as the two-set reduction gear method for planetary reduction. The planetary gear (2-1) is fixed to the ball cage shell (2-4) through the planetary gear fixing shaft (2-2), and the sun gear (2-3) is fixed to the ball cage shell (2-4) with screws. Finally, a whole ball cage planetary gear unit (2) is formed, which surrounds the planetary gear (2-1) and fixes the planetary gear fixing shaft (2-2) on both sides, making it more stable, smoother to run, and with lower noise. It turns scattered gears into a unit part, making assembly more convenient and accurate, less likely to be missed, and improving assembly efficiency and assembly quality.

[0005] The advantages of this invention are: stable structure, long service life, smooth operation, and low noise.

[0006] Easy to assemble, improving assembly efficiency Attached Figure Description Figure 1 This is a structural diagram of the overall internal structure of the planetary gearbox of a shaft-type window opener according to this utility model.

[0007] Figure 2 This is a finished product display diagram of a planetary gearbox structure for a shaft-type window opener according to this utility model.

[0008] Figure 3 This utility model relates to a ball-cage planetary gear unit.

[0010] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0011] like Figure 1 As shown, the ball cage planetary gear unit (2) is located inside the motor reducer housing (3) and is used to reduce the speed of the motor (5) through the planetary gear set to increase the output torque.

[0012] like Figure 3 As shown, the ball cage planetary gear unit (2) uses a planetary gear fixing shaft (2-2) to fix the planetary gear (2-1) to the ball cage shell (2-4), and uses screws to fix the sun gear (2-3) to the ball cage shell (2-4), forming a unit part as a whole.

[0013] Example 1: Our company's ball cage planetary gear unit (2) is used as a two-set reduction gear method for planetary reduction. The planetary gear (2-1) is fixed to the ball cage shell (2-4) through the planetary gear fixing shaft (2-2), and the sun gear (2-3) is fixed to the ball cage shell (2-4) with screws, thus forming an integral ball cage planetary gear unit (2). The planetary gear (2-1) is surrounded by the planetary gear (2-1), and the planetary gear fixing shaft (2-2) is fixed on both sides, making it more stable, smoother in operation, and with lower noise. The scattered gears are turned into a unit part, making the assembly more convenient and accurate, less likely to be missed, and improving the assembly efficiency and assembly quality.

[0014] This solution can also achieve the above functions by adjusting the number of planetary gears.

[0015] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
