1. Summarize
Freewheel and Overrunning Clutch makes use of the speed change of relative motion between the driving and driven clutch or the circumgyrate directional counterchange to make it automatic joint or come away. It is transmission essential part of the integration of machinery mechanical. Its main function is preventing the reversal, the pinpointing, passing the transmiting torque, shutting off the torque. Therefore, some professions call it counter stopping or the unidirectional bearing.
2. Range of use
Freewheel and Overrunning Clutch made by our company is mainly used for General machinery, Packaging machinery, Printing machinery, Petrifaction, Crane and transporter, High-voltage switch, Air blower, Speed reducer, compressor, machine tool and so on. Non-standard products can be offered in terms of the requirement from user. If you need more information, please contact us.
3. Selection
Type
The type is selected in terms of requirement for transmission, working condition and mounting details, referring to the structural character of our products. We also design and manufacture special products according to the technical information that you offer us.
Norms
The norms are mainly selected in terms of mean torque Tn, driving power, rated rotating speed and mounting detail. Usually, the following condition should be satisfied for calculated torque Tc.
Tc=β•T<Tn
4. Installation and usage
1). The freewheels must be mounted to ensure that the rotating of the freewheel is absolutely the direction required for main machine.
2). The coupling outer ring and organism, the inner rim and the axis, the key and the key slot coordination for moves the coordination, does not have excessively to be tight. Do pay attention to the elimination of burr, the clean, dries and evenly spread lubricates, and lightly strikes the backing strip with the bright and clean smooth metal thick pad in the coupling end surface with the hammer, strictly prohibits hardly knocking with assembles forcefully before assembly. At the same time also should guarantee the coupling outer ring half body and the inner rim must have the good proper alignment (to be smaller than 0.05mm). If the proper alignment ultra difference, it will affect the coupling normal rotation.
3). The coupling should use appropriate, the right amount lubricating oil or 2lithium bases lubricant carries on the lubrication, when leaves the plant it has poured into enough lubricating oil and lubricant.
4). In(During) the use, the working rotating speed of freewheel should be lower than the rated rotating speed. If working at high speed for long time , lubrication and cooling should be provided.
5). When it doesn’t work properly, should shutdown promptly and check, regarding to the special details solution.
6). This notice for installs the use notice generally. Or has the special request regarding each kind the coupling to install the use, please for details see this type coupling the use notice.
5. Lubrication & maintenance
Every type clutches have been lubricated with grease, which grease used in a long life type with high thermal and chemical stability. Therefore no maintenance need from three month to six month according to difference of environment and operation. Afterword grease should be checked, cleaned, changed regularly. Recommend change grease every six months or three months in a dirty environment, to a bore size above 200mm after half year of operation.
Some type clutches lubricated with oil in operation regularly and the level should be checked. Pay attention to the use scope . Grease and oil including graphite and molybdenum should be avoid and pay attention to limits of to use.
