Detailed Description
As shown in fig. 1-3, a high-strength anti-drop double sprocket comprises 2 sprocket bodies, as shown in fig. 2, the high-strength anti-drop double sprocket body comprises a first sprocket body 1 and a second sprocket body 2 which are arranged side by side, the first sprocket body 1 and the second sprocket body 2 are jointly sleeved on an axle 3, and a certain gap is reserved between the first sprocket body 1 and the second sprocket body 2 for installation of an anti-wave mechanism. The size of the gap is determined by the specific size of the anti-fluctuation mechanism, and the gap is not suitable to be too large, and is usually about 5-10 CM.
As shown in fig. 2, an anti-fluctuation mechanism is arranged between the first wheel body 1 and the second wheel body 2, the anti-fluctuation mechanism includes a supporting rod 4, one end of the supporting rod 4 is provided with a shaft sleeve 5, and the shaft sleeve 5 is sleeved outside the wheel shaft 3 and connected with the wheel shaft 3 through a central bearing to form a running fit. Through rotating the supporting rod 4, the direction of the anti-fluctuation mechanism can be adjusted at will to meet the requirement of chain assembly. As shown in fig. 1, the other end of the strut 4 extends obliquely to the upper sides of the first wheel body 1 and the second wheel body 2, and mounting shafts 6 are arranged on both sides of the strut 4.
Install and be provided with chain pinch roller 7 on the axle 6, chain pinch roller 7 and installation axle 6 normal running fit, and the position of the chain pinch roller 7 of both sides is relative with first wheel body 1 and second wheel body 2. That is, the chains mounted on the first wheel 1 and the second wheel 2 can be pressed by the corresponding chain rollers 7 to prevent the fluctuation. Because the utility model discloses a branch 4 is installed on shaft 3 through axle sleeve 5, considers compressing tightly fixedly, the anti-fluctuation mechanism is still including being used for compressing tightly the regulator that compresses tightly on the chain with chain pinch roller 7.
To the chain of different models, its width has certain difference, in order to realize better compressing tightly, realizes the miniaturization of device simultaneously, the utility model discloses should the supporting chain pinch roller 7 of adaptation. For this reason, chain pinch roller 7 should be convenient for change and assembly, as shown in fig. 2, the end of overhanging of installation axle 6 is provided with external screw thread and adaptation has fastening nut 15, the one end that installation axle 6 is close to branch 4 is provided with interior fender head 16, and installs and overlap in proper order on the axle 6 along keeping away from the direction of branch 4 and be equipped with interior plane bearing 17, chain pinch roller 7, outer plane bearing 18 and fastening nut 15. The chain pinch roller 7 is connected with the mounting shaft 6 through a wheel bearing, and the chain pinch roller 7 is compressed tightly through a fastening nut 15 in the axial direction. In this way, the chain pinch roller 7 can be quickly replaced by removing the fastening nut 15, the outer flat bearing 18 and the like. The inner flat bearing 17 and the outer flat bearing 18 can ensure stable rotation of the chain pinch roller 7. In order to further improve the transverse limiting effect of the chain pinch roller 7 on the chain, two ends of the chain pinch roller 7 are provided with protective edges 19, and the space between the protective edges 19 is matched with the chain.
The utility model discloses in the use, with the chain installation back that targets in place, rotate branch 4, branch 4 drives the chain pinch roller 7 of installing on it and compresses tightly the chain to guarantee the tensioning of chain. Because axle sleeve 5 adopts the pivoted mode to install on shaft 3, its regulation that conveniently carries out the angle can adapt to the installation demand of various differences, utilizes to compress tightly the chain with 4 end installation's of branch chain pinch rollers 7 and compresses tightly the chain that the regulator can be quick, and it is also very convenient to use. The double-row chain wheel form combining the first wheel body 1 and the second wheel body 2 is adopted, so that the double-row chain wheel has larger transmission load and is suitable for high-strength transmission operation.
About compressing tightly the concrete structure of regulator, the utility model discloses the mode that can adopt does, a coil spring, and coil spring's one end is connected with branch 4's middle part, and the other end is connected with fixed basis to take tight branch 4 through coil spring, and then take tight chain pinch roller 7. However, in order to adapt the pressing force, it is also possible that, as shown in fig. 3, the pressing adjuster includes a fixing base 8, and a hinge lug 9 is provided above the fixing base 8 and connected to one end of a threaded sleeve 10 through the hinge lug 9. And a matched adjusting screw rod 11 is arranged in the other end of the threaded sleeve 10, one end, far away from the threaded sleeve 10, of the adjusting screw rod 11 is connected with one end of a connecting rod 12, and the other end of the connecting rod 12 is connected with the middle section of the supporting rod 4 through a tension spring 13. The middle section of the connecting rod 12 is provided with a rotary joint 14.
By rotating the adjusting screw rod 11, the length of the screw rod 11 extending into the threaded sleeve 10 can be adjusted by dry-frying, so that the overall length of the compression adjuster is changed to meet various different tensioning pressure requirements. Theoretically, the longer the adjusting screw 11 extends into the threaded sleeve 10, i.e., the shorter the length of the compression adjuster, the greater the tensioning pressure can be provided; otherwise, the smaller the size is, and the staff can carry out allocation according to the actual situation.
