Description

Technical Field

[0001] This utility model relates to the field of belt pulley equipment, and specifically to a belt pulley rotary transmission mechanism. Background Technology

[0002] Belt pulley rotary transmission mechanisms are widely used in industrial machinery, automotive power systems, agricultural equipment and other fields due to their simple structure, low cost and convenient maintenance. They transmit power through the frictional meshing of the belt and the pulley.

[0003] In traditional transmission mechanisms, belt tension relies on the fixed adjustment of the drive pulley's mounting position. Once installed, it cannot dynamically adapt to the belt's natural slack, such as elastic deformation after long-term use or length expansion and contraction due to temperature changes. When the belt is too loose, slippage is likely to occur, which not only reduces transmission efficiency but also accelerates belt wear due to frictional heat. If the belt is too tight, it will increase the load on the pulley and axle, leading to premature bearing failure and shortening the equipment's lifespan.

[0004] Therefore, it is necessary to invent a belt pulley rotation transmission mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a belt pulley rotation transmission mechanism. By setting up a slidingly adjustable auxiliary mechanism, locking components, and positioning components, it can solve the problems in the prior art where the belt tension cannot be dynamically adjusted, resulting in the belt slipping due to being too loose or damaging components due to being too tight, and it cannot adapt to the natural slackness or length changes of the belt.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a belt pulley rotation transmission mechanism, comprising,

[0007] The wheel body is provided in two sets, and the two sets of wheel bodies are connected by a belt for transmission.

[0008] An auxiliary mechanism is provided on the outside of the belt body. The auxiliary mechanism includes a base, on which three sets of mounting seats are fixedly installed. Two sets of support members are fixedly connected to the outside of the three sets of mounting seats. A movable member is slidably connected to the outside of the front part of the support member. An auxiliary wheel is rotatably connected to the outside of the movable member through a bearing. The auxiliary wheel contacts the outside of the belt body. A positioning component is slidably connected to the outside of the rear part of the support member. A locking component is provided on the inner wall of the front set of mounting seats.

[0009] Preferably, the locking assembly includes a bolt and a damping nut. The bolt is threaded through and connected to the inner wall of the front set of mounting seats. The rear side of the bolt abuts against the front side of the moving part.

[0010] Preferably, the positioning component includes a movable frame, a fastener, and a slot. The movable frame slides on the outside of the support member.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1 - Figure 3 The pulley rotation transmission mechanism shown includes a pulley body 1 and an auxiliary mechanism 3, specifically:

[0024] The wheel body 1 is provided with two sets of pulleys, which are used to install on the device that needs to be driven, such as the output shaft of the motor and the rotating shaft that needs to be driven. The two sets of wheel bodies 1 are connected by a belt body 2. The belt body 2 is the belt body, usually a V-belt, multi-ribbed belt, etc. By fitting with the groove of the wheel body 1 and the groove of the auxiliary wheel 36, the rotational power of the driving wheel body 1 is transmitted to the driven wheel body 1. Its tension directly affects the transmission efficiency and needs to be adjusted by the auxiliary mechanism 3 to avoid slippage or overstretching.

[0025] The auxiliary mechanism 3 is located on the outside of the belt body 2. The auxiliary mechanism 3 includes a base 31 with mounting holes, which can be fixed to the equipment frame with screws for device installation. Three sets of mounting seats 32 are fixedly installed on the upper part of the base 31, arranged in a triangle along the length of the base 31, for fixing the support member 33. Two sets of support members 33 are fixedly connected to the outside of the three sets of mounting seats 32, which are the sliding tracks of the moving member 34 and the positioning component 38. The moving member 34 is slidably connected to the front outer side of the support member 33, and can slide back and forth along the support member 33 to adjust the contact pressure between the auxiliary wheel 36 and the belt body 2. The auxiliary wheel 36 is rotatably connected to the outside of the moving member 34 through the bearing 35. The bearing 35 reduces frictional resistance and ensures that the auxiliary wheel 36 rotates smoothly and synchronously with the belt body 2. The auxiliary wheel 36 contacts the outside of the belt body 2. The positioning component 38 is slidably connected to the rear outer side of the support member 33. A locking component 37 is provided on the inner wall of the front set of mounting seats 32.

[0026] like Figure 1 and Figure 2 As shown, the locking assembly 37 includes a bolt 371 and a damping nut 372. The bolt 371 is threaded through and connected to the inner wall of a set of mounting seats 32 on the front side. The rear side of the bolt 371 abuts against the front side of the moving part 34. By rotating the bolt 371, the moving part 34 is pushed to slide backward along the support 33, thereby adjusting the pressure of the auxiliary wheel 36 on the belt body 2 and realizing fine adjustment of the tension. Two sets of damping nuts 372 are provided. The two sets of damping nuts 372 are respectively located on the front and rear sides of the bolt 371 near the set of mounting seats 32 on the front side. After tightening, the position of the bolt 371 is locked by friction to prevent it from loosening in the vibration environment and to ensure the stability of the position of the moving part 34 and the auxiliary wheel 36.

[0027] like Figure 1 - Figure 3As shown, the positioning component 38 includes a movable frame 381, a fastener 382, ​​and a slot 383. The movable frame 381 slides on the outside of the support member 33. The outer side of the movable frame 381 is also equipped with an auxiliary wheel 36 and a bearing 35. The movable frame 381 functions similarly to the movable member 34, moving along the support member 33. It cooperates with the front auxiliary wheel 36 to support the belt body 2 from both sides, enhancing tension stability. The fastener 382 is threaded onto the upper inner wall of the movable frame 381. Tightening the fastener fixes the movable frame 381 in a selected position. Its cooperation with different slots 383 allows for adjustment of the auxiliary wheel 36's position, adapting to changes in the length of the belt body 2. The upper part of the support member 33 has a slot 383, which cooperates with the fastener 382 to form a positioning structure. The lower part of the fastener 382 abuts against the inner wall of the slot 383. The support member 33 is T-shaped. The auxiliary wheel 36 has a groove on its outer side that fits the belt body 2, increasing the contact area with the belt body 2 to improve the tension effect, and the groove edge also constrains the belt body 2 from offset. Multiple sets of slots 383 are evenly distributed, providing different fixed positions, which facilitates quick adjustment of the position of the auxiliary wheel 36 according to the tension requirements of the belt body 2 without the need for fine calibration.

[0028] The working principle of this utility model is as follows: First, two sets of wheels 1 are installed on the output shaft of the power source and the rotating shaft of the driven equipment, respectively. They are connected by winding with belt 2 to form a basic transmission link. The auxiliary mechanism 3 is fixed on the equipment frame by the base 31. The three sets of mounting seats 32 on its upper part support two sets of T-shaped support members 33, providing sliding tracks for the moving part 34 and the positioning component 38.

[0029] According to the initial tension of the belt 2, adjust the position of the auxiliary wheel 36. For the front auxiliary wheel 36, rotate the bolt 371 on the front mounting base 32 to push the moving part 34 to slide backward along the support 33, so that the auxiliary wheel 36 on the outside of the moving part 34 is close to the outside of the belt 2. When the tension of the belt 2 is appropriate, tighten the damping nuts 372 on both sides of the bolt 371 to lock the position of the bolt 371 by friction and prevent the moving part 34 from loosening.

[0030] For the rear auxiliary wheel 36, the sliding frame 381 is adjusted along the support member 33 so that the outer auxiliary wheel 36 fits against the other side of the belt body 2. Then, the fastener 382 on the upper part of the sliding frame 381 is tightened so that its lower part abuts against the corresponding slot 383 in the support member 33. After the rear auxiliary wheel 36 is fixed, the grooves on the outer sides of the front and rear auxiliary wheels 36 fit against the edge of the belt body 2, which ensures the belt body 2 is tensioned by pressure and restrains the belt body 2 from offset by the grooves.

[0031] After the equipment is started, the driving wheel 1 rotates and drives the driven wheel 1 to rotate synchronously through the belt 2. The auxiliary wheel 36 rotates flexibly through the bearing 35 under the action of the friction of the belt 2. If the belt 2 becomes loose due to long-term use, the above steps can be repeated.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
