HIGH PERFOMANCE HFL0822KFR DRAWN CUP NEEDLE CLUTCH
Drawn Cup Needle Roller Cluth and bearing components of HFL Series HFLZ Series
Drawn Cup Needle Roller Cluth and bearing components HFL ,HFLZ Series of two into one of the supporting bearings may be supported as a special space-saving . Needle roller bearing bearings mounted on the both sides of the clutch and radial laoad bearing needle roller bearings and plastic cage components.
Torque transmission capability
The adoption of the recommended installation tolerances, can deliver a maximum torque depends on seat shell and shaft materials, strength,thickness and so on. The forces generated in the clutch there is sufficient wall thickness and the corresponding strength of the materials can withstand the next.
Switching frequency and Conversion Accuracy
Because the radial cross-section thin, needle roller clutch moment is small, each needle has a separate spring support to maintain the shaft, needle roller ,stamping outside the circle of constant contact between the inclined plane, so it allowed a higher switching frequency and conversion accuracy. In addition to the level of conversion accuracy and conversion frequency dependent, but also with the lubrication, with the choice of the . Adjacent pieces of elastic deformation and the driving force through the shaft or the outer ring to pass. At high frequencies , the driving force generally pass through the shaft.
Performance test
The clutch outer ring of the stamping plant test is use a seat belt hole and shaft tolerance N6/h5 the upper and lower limits of the plug and ring at the same time to wishstand the torque of about 0.15Md perm using ring is hardened steel ring , pore size made of precision grinding , the minimum wall thickness of 20mm.
Operation temperature and lubrication
Drawn Cup Needle Roller Cluth,such as proper lubrication can be -30 degress Celsius to 120 degress Celsius temperature range, long-term operation, to temperatures below -10 degress Celsiuso or a high speed with the 0.7*nj , when ,in order to ensure the Drawn Cup Needle Roller Cluth normal function should use the recommended lubricant consultation. Grease lubrication in most application is sufficient, so the factory has been pre-populated with the national standard of high quality lithium based grease ,its application temperature of -10 degress Celsiuso to 70 degress Celsiuso. For temperatures over 70 degress Celsius conditions, recommended oil lubrication.
Installation tolerances
Installation, shaft and seat hole should have a 15°chamfer, in order to achieve the best installation conditions. Only loaded seat hole, the needle and pressing the clutch outer ring in order to be thin-walled concentric contours of its without any additional axial location. Installation tolerances and Drawn Cup Needle Roller Bearings same as in Table 1. Block hole surface roughness is Ro0.8. For non-rigid bearing is required for installation tests, in order to determine tolerance limits of the same work to get the desired gap. Geometric precision cylindrical bearing bore must be IT5/2 value of half of the range.
Special Note
Should be used to assemble the roller clutch pressure mandrel seated hole, when the clutch on the relative direction of the arrow shaft when the clutch will be locked rotation, and therefore should pay attention to locking before assembly. Only in accordance with the recommended tolerances can guarantee proper locking and beyong clutch.
