Description

Technical Field

[0001] This utility model relates to the field of window opener technology, specifically to a gear drive device. Background Technology

[0002] The core function of a gear drive is to transmit power from the input shaft to the output shaft, while simultaneously converting speed, torque, and direction of motion. It is widely used in the power transmission systems of mechanical equipment. Gear drives transmit power through gear meshing, converting the power output from an engine or motor into mechanical energy to drive equipment. By using gear combinations with different gear ratios, speed adjustment and torque amplification can be achieved.

[0003] The prior art, "Device with Drive Adapter Gear Structure", application number CN202110430053.7, includes: a rack meshing with a driven mechanism; a driving mechanism meshing with the driven mechanism to drive the drive adapter gear structure to perform linear motion; the drive adapter gear structure is fixed on a drive platform above the drive adapter gear device; a fixed platform is provided above the drive platform; slide rails are fixed on both sides of the fixed platform; a rack on the drive adapter gear structure is fixed below the slide rails; and the drive adapter gear structure drives the drive platform to slide on the slide rails.

[0004] The current drive adapter gear structure is suitable for drive platform applications, but in window opener structures, the current adapter gear drive structure is too large and cannot be matched with the window frame and window opening and closing transmission structure. Summary of the Invention

[0005] This utility model mainly addresses the shortcomings of existing technologies by providing a gear drive device with simple structure, good performance, and strong operational stability. It is a precision mechanical transmission unit integrating driving, deceleration, torque conversion, and direction adjustment. It employs a single-shaft motor, achieving dual-shaft output at both ends of the motor through gear coupling.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A transition gear drive device includes a base with an end cover. A transition gear assembly extending from both ends of the end cover is provided between the base and the end cover. The transition gear assembly includes a planetary geared motor. One end of the planetary geared motor has a drive output shaft that is inserted into and fixedly positioned within the motor. A drive gear is mounted on the drive output shaft. The other end of the planetary geared motor has a driven output shaft with a driven gear. A transition shaft, parallel to the planetary geared motor, is located on the side of the motor. Both ends of the transition shaft have transition gears that mesh with the drive gear and the driven gear, respectively.

[0007] Planetary geared motors provide rotational power and achieve high torque and low speed output through the first stage of reduction via their internal planetary gear sets. The specifications for the driving and driven gears are 20×1.25, and the specifications for the transition gears are 10×1.25. 20×1.25 and 10×1.25 represent the number of teeth × module.

[0008] Preferably, a coupling sleeve is provided between the active output shaft and the planetary geared motor. This compensates for minor shaft alignment errors, buffers impacts, and smoothly transmits the motor torque to the active output shaft.

[0009] Preferably, bearings are provided on both sides of the driving gear, both sides of the driven gear, and both sides of the adapter gear. Deep groove ball bearings are used to ensure smooth, low-friction operation of all rotating components.

[0010] Preferably, the end cap is provided with a number of screws that are threadedly connected and fixed to the base.

[0011] Preferably, the base has several mounting countersunk holes on both sides.

[0012] This invention can achieve the following effects: This invention provides a gear drive device, which, compared with existing technologies, features a simple structure, good performance, and strong operational stability. It is a precision mechanical transmission unit integrating driving, deceleration, torque conversion, and direction adjustment. It employs a single-shaft motor, achieving dual-shaft output at both ends of the motor through a gear drive mechanism.

[0013] Compact structure and high integration: The motor, reducer, gear transmission system and support bearing are highly integrated into a closed unit consisting of a base and end cover, saving installation space.

[0014] Flexible output and strong adaptability: The dual output shaft design, combined with the adapter gear, can easily provide synchronous and unidirectional power output to the equipment on both sides, making it suitable for complex mechanisms that require dual-side drive.

[0015] High transmission precision and good stability: All shafts are supported by precision bearings, ensuring the accuracy of gear meshing, smooth operation, low noise, and low vibration.

[0016] High load-bearing capacity and large torque: The planetary geared motor itself has the characteristic of high torque output, coupled with a robust gear transmission system, enabling the entire device to withstand large loads.

[0017] Easy installation and maintenance: The standardized base (with countersunk holes) and end cap (fixed with multiple screws) design makes the installation, positioning, disassembly and maintenance of the device very simple. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] Example: Figure 1-4 As shown, a transition gear drive device includes a base 1 with two mounting countersunk holes 5 on both sides. An end cover 2 is provided on the base 1, and eight screws 3 are threadedly fitted onto the end cover 2 for fixing. A transition gear assembly 4 extending from both ends of the end cover 2 is provided between the base 1 and the end cover 2. The transition gear assembly 4 includes a planetary geared motor 8. One end of the planetary geared motor 8 has a drive output shaft 14 that is inserted and fixedly positioned within the planetary geared motor 8. A coupling sleeve 13 is provided between the drive output shaft 14 and the planetary geared motor 8. A drive gear 7 is provided on the drive output shaft 14, and a driven output shaft 10 is provided at the other end of the planetary geared motor 8. A driven gear 9 is provided on the driven output shaft 10. A transition shaft 12, parallel to the planetary geared motor 8, is provided on the side of the planetary geared motor 8. Both ends of the transition shaft 12 have transition gears 11 that mesh with the drive gear 7 and the driven gear 9, respectively. Bearings 6 are provided on both sides of the driving gear 7, both sides of the driven gear 9, and both sides of the adapter gear 11.

[0025] Working principle: Power generation and primary reduction: After the planetary geared motor 8 is powered on, its high-speed rotating motor rotor is converted into low-speed, high-torque rotational motion through the planetary reduction mechanism.

[0026] Bidirectional output: The rotational motion is transmitted simultaneously to the active output shaft (14) and the driven output shaft (10) at both ends through the dual output shaft structure.

[0027] Active side drive: Active output shaft 14 drives active gear 7 to rotate.

[0028] Shifting and synchronizing: The rotation of the driving gear 7 drives the shift gear 11 that meshes with it. Since the shift gear 11 is mounted on a fixed shift shaft 12, it rotates around the shaft and simultaneously drives the driven gear 9 that meshes with it.

[0029] Driven output: The final driven gear 9 is driven to rotate and outputs power through the driven output shaft 10.

[0030] Key transmission characteristics: Due to the presence of the adapter gear 11, the driving gear 7 and the driven gear 9 rotate in the same direction. If the driving gear and the driven gear have the same number of teeth, their rotational speeds are also the same; if the number of teeth is different, a second stage of deceleration or acceleration can be achieved.

[0031] In summary, this adapter gear drive device features a simple structure, good performance, and strong operational stability. It is a precision mechanical transmission unit integrating driving, reduction, torque conversion, and direction adjustment. It employs a single-shaft motor, achieving dual-shaft output at both ends of the motor through gear coupling.
