Description
Technical Field
The utility model belongs to the technical field of tensioning mechanisms, and particularly relates to a cylinder tensioning mechanism for a roller gear-joint machine.
Background
At present, after a chain transmission works for a period of time, abrasion, abnormal sound, looseness and the like are generated, the working capacity of the chain transmission is influenced, therefore, a certain initial tension force needs to be ensured by adopting a tensioning measure, the tensioning is mainly performed by adding a tension spring, a spring and the like in the conventional tensioning form on the market, when the conventional roller gear coupling is used, the roller needs to be reversed to meet the use requirement, the roller gear coupling is easy to reduce the mechanical performance after continuously running for a period of time due to the fact that the tension spring has batch quality problems in elasticity and rigidity, the usability of the machine is influenced, particularly, the roller gear coupling needs to be lifted up when being maintained, the tension spring cannot recover to a certain initial tension force after falling, the usability of the machine is influenced finally, and certain loss is caused to a user.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, provides the cylinder tensioning mechanism for the roller gear joint, can solve the problem that the mechanical property of a tension spring is reduced after the tension spring is used for a long time, is extremely convenient to use, and greatly reduces the production cost.
In order to achieve the purpose, the utility model adopts the technical scheme that:
the utility model provides a cylinder straining device for roller tooth connects, includes frame, driven sprocket I, driven sprocket II, drive sprocket, tensioning sprocket, chain, mount, screw rod, telescopic cylinder, swinging boom, motor, speed reducer, frame one side is equipped with the motor, and the motor output is connected with the speed reducer, and the gear that the speed reducer output was established is connected with the gear engagement that drive sprocket one side was established, and drive sprocket passes through the chain and is connected with driven sprocket I, driven sprocket II, tensioning sprocket meshing, and driven sprocket I, driven sprocket II are installed in roller one end with drive sprocket, and tensioning sprocket movable mounting is on the swinging boom, and swinging boom other end movable mounting is in the frame, swinging boom one side swing joint telescopic cylinder.
The telescopic cylinder base is movably provided with a screw rod, the screw rod is installed on a fixing frame through thread engagement, and the fixing frame is fixedly installed on one side of the rack.
Preferably, the telescopic cylinder can be replaced by a hydraulic telescopic oil cylinder or an electric push rod, and the tension can be adjusted freely through telescopic.
Compared with the prior art, the utility model has the beneficial effects that:
1) the motor drives the gear to rotate, the gear drives the driving sprocket to rotate through meshing transmission, power transmission is realized by meshing the driven sprocket I and the driven sprocket II through the chain, finally, the chain tightness is adjusted by increasing the time of tensioning the sprocket, when the gear-type clutch gear machine runs, the air inlet position of the throttle valve of the telescopic cylinder is in an inflated state, and the telescopic cylinder realizes the tightness condition of the chain by adjusting the position of the tensioning sprocket, so that the gear-type clutch gear machine can run normally;
2) the gear machine is at maintenance's in-process, need mention upper roller subassembly and overhaul, can deflate telescopic cylinder this moment, remove the tensioning sprocket, realize loosening of chain, make upper roller subassembly can conveniently dismantle, replace former extension spring, the spring structure of usefulness through telescopic cylinder, can increase machine stability, can avoid spring, extension spring tensile force because of the machine instability that batch problem brought for the machine motion is more stable.
