Problems solved by technology

[0003] The direction of the transmission device is usually divided into two directions: x-axis and y-axis. For a transmission device with a long transmission length, it is necessary to ensure that the length of the toothed belt cannot be too long or too short, otherwise the toothed belt will not be vertical or not due to gravity. Horizontal, after several times of high-speed transmission, the non-vertical or non-level situation of the toothed belt will become more and more obvious, which will reduce the load of the main drive toothed belt pulley, thus directly affecting the normal operation of the transmission device

Embodiment

[0018] Example: such as figure 1 with figure 2 As shown, the toothed belt tensioning device in this embodiment mainly includes a base 1, a toothed block 2 and a toothed belt pressing block, wherein the toothed block 2 and the toothed belt pressing block are installed on the bottom of the base 1 respectively. The inside of the cavity is semi-closed, and the toothed belt pressing block is located above the toothed block 2.

[0019] Such as Figure 2-4 As shown, the cross-section of the base 1 is trapezoidal, and the openings at both ends of the semi-closed cavity inside it are inclined downward. A toothed block 2 is placed at the left and right ends of the semi-closed cavity surrounded by the base 1. The edge of the toothed block 2 is flush with the edge of the cavity surrounded by the base 1. Convex teeth that match the tooth profile. The base 1 is provided with a narrow and long through hole 13, and a bolt 14 is arranged in the narrow and long through hole 13, and the too...

Abstract

The invention relates to the field of mechanical equipment, in particular to a toothed belt tensioning device. The toothed belt tensioning device is characterized by comprising a base. A semi-sealed cavity is formed in the base in a cut-through mode. A toothed block is arranged in the semi-sealed cavity and fixedly connected to the base, and convex teeth are arranged on the surface of the toothed block. A pressing block is arranged above the toothed block, an interval is reserved between the pressing block and the surface of the toothed block, and the pressing block is installed in the base. The end surface of the opening end of the semi-sealed cavity, one lateral surface of the toothed block and part of the pressing block all incline downwards. The toothed belt tensioning device has the advantages that the toothed block is arranged in the trapezoid base, so that it is guaranteed that a toothed belt does not slide in a fixing device; the waist in the trapezoid structure can also guarantee that the toothed belt keeps tensioned or vertical or horizontal all the time.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a toothed belt tensioning device. Background technique [0002] The toothed belt is a common transmission part in the transmission device. The toothed belt must have sufficient tension in the transmission device to ensure that the force generated between the toothed belt and the drive toothed belt prevents the toothed belt from slipping, thereby ensuring the transmission normal operation of the device. [0003] The direction of the transmission device is usually divided into two directions: x-axis and y-axis. For a transmission device with a long transmission length, it is necessary to ensure that the length of the toothed belt cannot be too long or too short, otherwise the toothed belt will not be vertical or not due to gravity. Horizontal, after multiple times of high-speed transmission, the non-vertical or non-level situation of the toothed belt will become more and more o...
