A manipulator is an automatic mechanical device widely used in robotics. It can be applied to industrial manufacturing, medical equipment, entertainment services, aerospace manufacturing, semiconductor manufacturing, space exploration, etc. The manipulator PTZ camera gear motor is a drive module used in the mechanical transmission equipment of the PTZ camera. Its main transmission structure is assembled by a driving motor (micro motor) and planetary gearhead (reducer). It is applied to the transmission gear motor module of robotic arm and gripper, short for “robotic gripper motor”. The driving motor can adopt BLDC motor, brush DC motor, stepper motor and coreless motor as the driving source while the micro gearbox can adopt planetary gearhead, cylindrical gearhead, and worm gearhead as the reducer. The technical parameters of manipulator PTZ camera gear motors are often customized for developments, including the output power, speed, gear ratio, torque, voltage, transmission precision, noise, service life, noise, working efficiency, etc.
ZHAOWEI Machinery & Electronics Co., Ltd is devoted to R&D, design and manufacturing of gear drive systems, which are widely applied to automobiles, 5G telecommunication, smart home, medical equipment, consumer electronics, robots, etc. The customized technical parameters of manipulator PTZ camera gear motors provided by ZHAOWEI are shown below:
Diameter: 3.4mm-38 mm
Output power: ﹤50W
Output speed: 5-1500rpm
Gear ratio: 2-2000
Output torque: 1.0 gf.cm -50kgf.cm
Project Name: Smart Motorized PTZ Camera Gearbox
Project Background: The cooperation between smart automatic PTZ platform and camera contributes to a larger monitoring range and greater value in use. It rotates horizontally and vertically under the action of the voltage control (the output voltage of the PTZ platform controller), enabling the camera to focus and capture the desired object for observation over a wide range. This kind of micro gearboxes can be used for PTZ cameras for panoramic aerial photography, UAV aerial photography, landscape photography, group picture, 3D panorama photography, virtual roaming production, etc.
Solution: ZHAOWEI firmly focuses on the development of micro gearboxes. The permanent magnet DC motor is adopted as the transmission mode and the worm gears and helical gears are used for the gearbox. This combination helps to effectively solve the problem brought by the vibration and noise of the motorized PTZ camera. The gap jitter will appear during the operation of the common PTZ platforms, but luckily, ZHAOWEI solves the problems of service life as well as gear backlash by the finite element analysis of the tooth shape.
