A timing belt with easy adjustment

Abstract

This application provides an easily adjustable synchronous belt, relating to the technical field of mechanical transmission. It includes a belt and pulleys, with the belt wound between the pulleys. The synchronous belt also includes a limiting frame, comprising a frame body, a pressure plate, and a limiting bolt. The frame body includes a limiting groove and an opening, with the opening located at the outer end of the limiting groove, and the pressure plate located at the opening. The limiting bolt passes through the frame body, and its front end is threadedly connected to the pressure plate. The belt passes through the limiting groove and rests against the pressure plate. The inner wall of the limiting groove limits the belt's position, preventing wear caused by lateral movement. As the belt rests against the pressure plate, the pressure plate moves outward, causing the upper part of the belt to move outward, increasing the distance between belts and increasing the belt tension, thus ensuring smooth belt operation. During belt operation, the position of the pressure plate can be adjusted outside the limiting frame without needing to insert a wrench between the belts, ensuring operational safety.

Description

Technical Field

[0001] This application relates to the technical field of mechanical transmission, and in particular to a synchronous belt that is easy to adjust. Background Technology

[0002] The core technical attribute of synchronous belts is mechanical transmission. They are a key fundamental component in mechanical engineering for achieving precise synchronous power transmission and motion control. Compared to gear and chain drives, belt drives offer advantages such as simpler mechanisms, lower noise, and lower equipment costs. They are widely used in the power transmission of various machines, penetrating almost all modern industrial, transportation, and consumer product sectors requiring precise transmission. A common type of belt used in machines is a ring-shaped belt fitted onto two pulleys.

[0003] Existing synchronous belts mainly have the following problems: the belt tension is adjusted by adjusting the distance between the pulleys, resulting in large changes in tension at high speeds; the belt is also prone to swaying left and right at high speeds, causing significant wear and affecting the stability of the belt's operating speed. Utility Model Content

[0004] To address the shortcomings of the aforementioned background technology, a synchronous belt that is easy to adjust is proposed.

[0005] This application provides an easily adjustable synchronous belt, including a belt and pulleys, with the belt wound between the pulleys; the synchronous belt also includes a limiting frame, which includes a frame body, a pressure plate, and a limiting bolt. The frame body includes a limiting groove and a slot, with the slot located at the outer end of the limiting groove and the pressure plate located at the slot; the limiting bolt passes through the frame body, and the front end of the limiting bolt is threadedly connected to the pressure plate; the belt passes through the limiting groove and rests against the pressure plate.

[0006] Preferably, the frame is provided with a limiting hole, and the limiting bolt is rotatably located in the limiting hole.

[0007] Preferably, the limiting hole is in the shape of a circular step, and the limiting hole includes a rear part and a front part from the outside to the inside. Both the rear part and the front part are cylindrical, and the bottom diameter of the rear part is larger than the bottom diameter of the front part. The diameter of the front part is adapted to the diameter of the front end of the limiting bolt.

[0008] Preferably, the rear end of the limiting bolt is provided with a limiting nut, and the outer diameter of the limiting nut is adapted to the diameter of the bottom surface at the rear.

[0009] Preferably, the synchronous belt further includes a support plate, which is fixedly disposed on the outer side of the belt; a limiting frame is fixedly disposed on the inner side of the support plate, and the support plate has a connecting hole, which is directly opposite the limiting hole.

[0010] Preferably, the connecting hole is cylindrical, and the diameter of the bottom surface of the connecting hole is not lower than the diameter of the bottom surface of the rear part.

[0011] Preferably, the frame is U-shaped and includes a bottom plate, a left side plate, and a right side plate. The left side plate and the right side plate are arranged parallel to each other, and the distance between the left side plate and the right side plate is adapted to the width of the belt.

[0012] Preferably, multiple limiting holes are provided and evenly distributed on the left and right side plates.

[0013] The beneficial effects of this utility model are:

[0014] The belt passes through the limiting groove, whose inner wall limits the belt's position, preventing wear caused by lateral swaying. The belt rests against the pressure plate. When the belt moves at high speed, the pressure plate moves outward, causing the upper part of the belt to move outward as well. This increases the distance between the upper and lower parts of the belt, increasing the tension and tightening the belt, ensuring smooth operation. The limiting bolt passes through the frame, and its front end is threaded into the pressure plate. During belt operation, the limiting bolt can be rotated and the pressure plate adjusted using a wrench (Hexagonal) outside the limiting frame, eliminating the need to insert the wrench between the upper and lower parts of the belt and ensuring operational safety.

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] Example

[0027] like Figures 1 to 3 As shown, an easily adjustable synchronous belt includes a belt 1 and pulleys 2, with the belt 1 wound between the pulleys 2. The synchronous belt also includes a limiting frame 3, which includes a frame body 31, a pressure plate 32, and a limiting bolt 33. The frame body 31 includes a limiting groove 311 and a slot 312, with the slot 312 located at the outer end of the limiting groove 311 and the pressure plate 32 located at the slot 312. The limiting bolt 33 passes through the frame body 31, and its front end is threadedly connected to the pressure plate 32. The belt 1 passes through the limiting groove 311 and rests against the pressure plate 32.

[0028] The belt 1 passes through the limiting groove 311. The inner wall of the limiting groove 311 is used to limit the position of the belt 1 and prevent the belt 1 from being worn due to left and right swaying. The belt 1 is against the pressure plate 32. When the belt moves at high speed, the pressure plate 32 moves outward, which drives the upper part of the belt 1 to move outward. The distance between the upper and lower parts of the belt 1 increases, and the tension on the belt 1 increases and becomes tighter, which can ensure the smooth operation of the belt 1. The limiting bolt 33 passes through the frame 31. The front end of the limiting bolt 33 is threaded to the pressure plate 32. During the operation of the belt 1, the limiting bolt 33 can be rotated and the position of the pressure plate 32 can be adjusted by using a wrench (internal hexagon) outside the limiting frame 3. It is not necessary to put the wrench between the upper and lower parts of the belt 1, which ensures the safety of operation.

[0029] The limiting hole 313 is in the shape of a circular step. The limiting hole 313 includes a rear part 3131 and a front part 3132 from the outside to the inside. Both the rear part 3131 and the front part 3132 are cylindrical. The bottom diameter of the rear part 3131 is larger than the bottom diameter of the front part 3132. The diameter of the front part 3132 is adapted to the diameter of the front end of the limiting bolt 33.

[0030] The rear end of the limiting bolt 33 is provided with a limiting nut 331, and the outer diameter of the limiting nut 331 is adapted to the bottom diameter of the rear part 3131.

[0031] The synchronous belt also includes a support plate 4, which is fixedly disposed on the outer side of the belt 1; a limiting frame 3 is fixedly disposed on the inner side of the support plate 4, and the support plate 4 has a connecting hole 41, which is directly opposite to the limiting hole 313. In this embodiment, the limiting frame 3 and the support plate 4 are also connected by bolts, and a connecting bolt 5 is provided between the limiting frame 3 and the support plate 4. The connecting bolt 5 passes through the support plate 4 from the outside to the inside and is threadedly connected to the limiting frame 3. There are 6 connecting bolts 5.

[0032] The connecting hole 41 is cylindrical, and the bottom diameter of the connecting hole 41 is not lower than the bottom diameter of the rear part 3131.

[0033] The frame 31 is U-shaped and includes a base plate 314, a left side plate 315 and a right side plate 316. The left side plate 315 and the right side plate 316 are arranged in parallel, and the distance between the left side plate 315 and the right side plate 316 is adapted to the width of the belt 1.

[0034] Multiple limiting holes 313 are provided and evenly distributed on the left side plate 315 and the right side plate 316; in this embodiment, there are 8 limiting holes 313, 4 on the left side plate 315 and 4 on the right side plate 316.
