Important Notes 2. Important Notes Please read these notes carefully before operating the equipment. Kistler is not responsible for damage that may occur when this system is used in any way other than that for which it is intended. 2.1 For Your Safety This product has been manufactured in compliance with current valid safety regulations.
P530 Measuring Hub for Tire Test Stands, Type 9295B 2.2 Warnings Kistler measuring hubs have been developed and manu- factured to the state of the art and according to the best technical knowledge. However, the high-performance components are not designed for unlimited service life as they are heavily utilized up to the permanent load and therefore subject to wear.
As a rule, modifications to instruments result in altera- tions of the operating instructions. In such cases, inquire at your Kistler distributor about the possibilities of updat- ing your documentation. The current instruction manuals are available for download from the Kistler website (www.

Mounting Instructions 4. Mounting Instructions Measuring hubs of Type 9295B are precision instruments and must be handled carefully. Please take note of the following: Do not drop the measuring hub or expose it to any hard knocks! The maximum force of such shocks could exceed the measuring range of the instrument and cause severe damage ...
P530 Measuring Hub for Tire Test Stands, Type 9295B 4.1.2 Special Notes Please comply with the following notes for correct mounting of the measuring hub: The measuring hub must be installed only by qualified persons who are familiar with devices of this type ...

Mounting Instructions 4.1.3 Measuring Hub Mounting Location The coordinate system of the measuring hub is designed so that, with horizontal drum axle and with the test instru- ment at the top, it conforms to the ISO system of coordi- nates applicable to the wheel force (Fig. 2). The measuring hub is provided with oil lubrication or grease lubrication and must therefore only be used in the position with its Fz axis upwards.
P530 Measuring Hub for Tire Test Stands, Type 9295B 4.2 Test Stand Connection Measuring hubs of Type 9295B1 and Type 9295B2 can be connected at the front side using 3xM16 or 4xM12 screws, or at the rear side using 8xM16 screws (scope of delivery).
Mounting Instructions 4.3 Mounting the Test Object The test object is mounted on the front side of the shaft, either directly or by using an appropriate adapter. The designated hole patterns are at 100/135 and 160 mm on the pitch circle diameters. Fig.
P530 Measuring Hub for Tire Test Stands, Type 9295B 4.4 Wheel Centering If the test object is mounted directly on the shaft, it is possible to mount an additional centering pin on the front side of the shaft (ø45 H7, 2xM6). This configuration may also be used for centering an intermediate adapter (see Fig.
Mounting Instructions 4.5 Mounting a Brake For mounting a brake, the rear side of the measuring hub provides 8xM12 on a pitch circle of 130 mm (see Fig. 6). Fig. 6: Brake installation - dimensions rotating parts are highlighted in blue 9295B_002-635e-12.16 Page 19...
P530 Measuring Hub for Tire Test Stands, Type 9295B 4.6 Other Mechanical Interfaces The shaft provides a through-going bore (M10x1 at the ends), which can be used for feedthrough of cables or compressed air. It is possible to mount a rotary encoder or a slip ring for compressed air or additional signals on the rear side of the shaft (centering ø36 H7, 3xM5 pcd 24 mm) - (see Fig.
Oil Lubrication 5. Oil Lubrication The circulating oil helps to keep the bearing friction low and is essential for a long service life of the bearings. In addition the oil also helps to cool the measuring hub. For tests under severe conditions (high speed/high loads) the lubrication system could be upgraded by using an additional cooling system (e.g.

P530 Measuring Hub for Tire Test Stands, Type 9295B 6. Operation The measuring hub is in part a rotating measuring system. The interface between the rotating shaft and the measuring hub is provided by means of two bearings. Bearings are parts subject to wear and therefore their service life largely depends on the loading and lubrication of the bearings.
Operation 6.2 Friction Torque M The friction of the RoaDyn P530 measurement hub is made up of the bearing friction and the friction of the seals and is also dependent on the lubricant used. The friction torque was determined by performing measurements on two different oil-lubricated measure- ment hubs.
P530 Measuring Hub for Tire Test Stands, Type 9295B 6.3 Warm-up Phase and Tk0 The base plate and the cover plate warp against each other as a result of the inhomogeneous increase in heat. This causes the sensors to measure an interior force (mainly in Y direction) that is dependent on the temperature drop via the sensor and that cannot be compensated for.
Operation 6.4 Service Life of Bearings The calculations are based on the following conditions (and ISO as well): Wheel offset e 38 mm Rotational speed n 1 000 min Tire radius R = 250 mm Tire radius R = 300 mm Tire radius R = 350 mm Service life of bearings f (F Service life of bearings f (F...

≤±2 Table 6: Crosstalk 7.3 Checking Calibration, Function Test and Recalibration Kistler recommends periodic (annual) checking of the cali- bration values and a function test of the measuring hub as well as the entire system. This provides certainty of fault-free functioning of the measuring hub. The customer receives a report of the results of the data that have been measured.
