The novel belt tensioning mechanism has a simple structure; the adjusting and mounting plate of the novel belt tensioning mechanism is connected with the adjusting screw through the rotating shaft so as to save the space and achieve wide adjusting range and reliability and stability in tensioning; and meanwhile, a buffer cushion is added so as to reduce the vibration and the noise.
Description
Technical field
The utility model relates to a kind of tensioning mechanism, is specifically related to a kind of belt tension mechanism of belt power plant.
Background technique
The belt power plant are applied in numerous machinery as a kind of transmission device commonly used, scrape as ceramic brick and calm down in the thick equipment or the like, because belt is not a perfectly elastic body, work under tensioning state for a long time, can relax because of plastic deformation occurring.This just makes the initial tension of band transmission reduce, and transmission capacity descends, even loses efficacy.For guaranteeing band transmission proper functioning, must replenish tensioning in good time.As shown in Figures 1 to 3, present known its structure of conventional belt tensioning mechanism comprises frame 1, regulates mounting plate 2 and adjusting screw rod 3.There are two kinds of mounting types in the belt power plant, a kind of is that belt motor 5 is installed on the adjusting mounting plate 2, driven pulley 41 is installed on the frame 1, another kind is that the belt motor installation is liked on the frame, driven pulley is installed in to be regulated on the mounting plate, its both mounting points are opposite, but Principles of Regulation are the same.Now with first kind of existing belt tension mechanism principle of mounting type explanation, belt power plant driven pulley 41 is installed on the frame 1, belt motor 5 is installed in to be regulated on the mounting plate 2, the rotating shaft of belt motor 5 connects driving pulley 42, these adjusting mounting plate 2 one ends are articulated on the frame 1 by hinging shaft 6, the other end is provided with waist shape adjusting mounting groove 21 and is connected with adjusting screw rod 3 one ends, the other end of described adjusting screw rod 3 is articulated on the frame 1 by hinging shaft 6, its tensioning principle is: by changing adjusting screw rod 3 at the relative position of regulating waist shape adjusting mounting groove 21 on the mounting plate, change and regulate mounting plate 2 angles of inclination, thereby regulate to be installed in and regulate belt motor 5 and driving pulley 42 on the mounting plate 2, reach the distance of regulating between driving pulley 42 and driven pulley 41 central rotating shafts, realize the tensioning adjusting.The regulation range of this structure is regulated the restriction of waist shape adjusting mounting groove 21 on the mounting plate, for increasing regulation range, just must increase the length that waist shape is regulated mounting groove, the size of regulating mounting plate so also increases big thereupon, and increase the length of regulating mounting plate in limited space, increase cost on the one hand, may the space take place with other equipment on the other hand and interfere, design mechanical difficulty and increase.The mounting groove of above-mentioned adjusting screw rod and waist shape adjusting simultaneously is fixedly clamped by locking nut 8 (described locking nut is divided into upper locking nut 81 and lower locking nut 82), locking nut gets loose under the shock effect of belt motor work easily, it is unreliable to cause the tensioning of belt tension mechanism to be regulated, and influences belt power plant transmission stability.
The model utility content
The purpose of this utility model is at the problems referred to above deficiency, the novel belt tension mechanism that provides that a kind of conserve space and regulation range are big, tensioning is reliable and stable.
In order to achieve the above object, the utility model is by the following technical solutions:
Novel belt tension mechanism, comprise frame, regulate mounting plate and adjusting screw rod, described adjusting screw rod one end is articulated on the frame by hinging shaft, and described adjusting mounting plate one end also is articulated on the frame by hinging shaft, and the described adjusting mounting plate the other end is connected by a rotating shaft with the other end of adjusting screw rod.
Further, the utility model comprises two adjusting screw rods, and it is connected with the rotating shaft two ends by locking nut respectively.
Above-mentioned adjusting mounting plate is provided with bearing and is connected with rotating shaft.
In order to reduce vibrations, above-mentioned hinging shaft is connected with frame by fixed block, and is provided with cushion pad between fixed block and the frame.
The utility model is simple in structure, and its adjusting mounting plate is connected by rotating shaft with adjusting screw rod, and conserve space and regulation range are big, tensioning is reliable and stable; Increase cushion pad simultaneously, reduce vibrations and reduce noise.

Below by the drawings and specific embodiments the utility model is further described:
Embodiment
Shown in Fig. 4 to 5, novel belt tension described in the utility model mechanism is applied to be used to regulate the tensioning state of belt in the belt power plant.
Novel belt tension described in the utility model mechanism, comprise frame 1, regulate mounting plate 2 and adjusting screw rod 3, driven pulley 41 is installed on the frame 1, regulate on the mounting plate 2 belt motor 5 is installed, driving pulley 42 is installed in the belt motor rotating shaft, is connected by belt between driving pulley 42 and the driven pulley 41.Described adjusting screw rod 3 one ends are articulated on the frame 1 by hinging shaft 6, and described adjusting mounting plate 2 one ends also are articulated on the frame 1 by hinging shaft 6, and described adjusting mounting plate 2 the other ends are connected by a rotating shaft 7 with the other end of adjusting screw rod 3.
Further, the utility model comprises two adjusting screw rods 3, and it is connected with the rotating shaft two ends by locking nut 8 respectively, and described locking nut is divided into upper locking nut 81 and lower locking nut 82, by the be locked position of adjusting screw rod 3 of its acting in conjunction.
Above-mentioned adjusting mounting plate 2 is provided with bearing and is connected with rotating shaft 7.
In order to reduce vibrations, above-mentioned hinging shaft is connected with frame by fixed block 9, and is provided with cushion pad 10 between fixed block and the frame.
Below come the utility model is further described by concrete tensioning Principles of Regulation:
Unclamp two adjusting screw rod upper locking nuts at first respectively, be fit to, tighten two upper locking nuts at last respectively and get final product with spanner synchronization regulation lower locking nut to belt tension.
In whole adjustment process, the adjusting screw rod elevation angle is with the automatic variation of screwing of lower locking nut, and respective change also takes place in the position of regulating mounting plate, thereby changes the centre distance of principal and subordinate's belt wheel.In the process that the adjusting screw rod elevation angle changes, it is vertical with adjusting screw rod that rotating shaft keeps automatically, can guarantee effectively that like this upper locking nut, lower locking nut and packing ring thereof and rotating shaft reliably compress.Improve the rigidity of whole belt power plant, vibrations are reduced, noise lowers.
This structure can realize regulating driving and driven center distance of belt wheel in a big way in the confined space, thereby makes belt remain tensioning, for the proper functioning of belt power plant provides guarantee.Advantages such as this structure has simple in structure, and is easy to operate, and tensioning is reliable.
