Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] The invention provides a toothed belt pressing device applied to a small stable platform, which is applied to a toothed belt transmission device, mainly aimed at a miniaturized two-axis photoelectric stable platform, and can also be extended to other fields. The toothed belt transmission device includes a support base plate 1. The motor drive shaft 2, the azimuth shaft 3 and the toothed transmission belt 8, the motor drive shaft 2 of the motor 10 is installed in parallel with the azimuth shaft 3, and is fixed on the support base plate 1, and the gear is used between the azimuth shaft 3 and the motor drive shaft 2. The toothed belt 8 is connected, and the load 13 is fixedly connected with the azimuth shaft 3 through the platform frame 12. The toothed belt pressing device of this embodiment includes sliding pulley I4, sliding pulley II14, sliding pulle...

Abstract

The invention discloses a toothed belt pressing device applied to a small stable platform. Two sets of toothed belt pressing devices respectively correspond to a motor drive shaft and an azimuth shaft. Each set of toothed belt pressing devices includes a longitudinal sliding wheel set and a transverse sliding wheel group, the horizontal sliding wheel group moves horizontally to drive the longitudinal sliding wheel to compress the toothed transmission belt, so as to realize the compression of the toothed transmission belt and the transmission device. The invention utilizes the sliding wheel for compression and fixation, and adjusts the degree of compression between the toothed transmission belt relative to the shaft system by adjusting the sliding wheel, which solves the problems of transmission belt slippage, extension, aging, etc., avoids the mechanical resonance of the servo system, and improves the adjustable bandwidth of the servo range; secondly, compared with the traditional two-axis frame photoelectric stabilized platform, it has high transmission efficiency and light weight.

Description

technical field [0001] The invention relates to the field of servo control systems, in particular to a toothed belt pressing device applied to a small stable platform. Background technique [0002] In recent years, there has been more and more market demand for miniaturized photoelectric stabilization platforms, and the main application fields include: security, fire protection, monitoring and other fields. Under the condition of high zoom field of view, the photoelectric stabilization platform not only requires high-precision anti-interference, but also has the characteristics of miniaturization and light weight. The drive mode of the shaft system of the traditional photoelectric stabilized platform is mostly torque direct drive, such as Figure 5 As shown, the advantages are high torque efficiency and high torque reserve. The disadvantage is that the volume and weight are too large, which is not conducive to the spatial arrangement of the whole platform, and it puts forwa...
