Powerful, durable, innovative and unique: Zimmer® Clamping and Braking Elements for linear positioning applications. Our products have been thoroughly developed and tested for tough, industrial applications. Our aim is not only to optimise products and adapt them to new requirements, we also want to open up new applications through innovative developments. Our construction series feature a number of special characteristics which are typical of all Zimmer® developments. High performance, maximum quality. Zimmer® clamping and braking elements offer a new and innovative approach for...

Technical Operation Principles Clamping, Braking and Areas of Use The MK/MKS/MKR/MKRS/MBPS/UBPS series are built with two parallel (synchronous) wedge slide gears, which means the lifting movements of the contact sections can be carried out from either side. Relative movements resulting from the clamping process are therefore not expected to occur. Care must however be taken to ensure the connection design is correct. The KWH/KBH/MCP/MCPS/ LCE/HK/HKR/ miniHK series are mounted on floating bearings and so no lateral forces are exerted on the connection design during the clamping process. The...

Hydraulic Connections The hydraulic clamping elements are prefilled with HLP 46 at the factory. The hydraulic connection is available on both sides, however one connection is sufficient for operation. Special care must be taken when exposing the rigid and flexible hydraulic inlet pipes to air, since airlocks can damage the sealing elements. Connection Design, Installation of the Clamping Elements To avoid adverse effects such as permanent rubbing on the linear guide, the connection must be designed strictly according to the load taken and requirements made. Any inclination of the clamping...

Calculation of the Braking Distance Theoretical calculation of the braking distance Example: Two guide carriages and a UBPS braking element (size 45) A (number of braking elements) F (holding force of braking element) tR (reaction time) tR (response time) m (mass) vO (initial speed) µG (dynamic friction) µG (static friction) g (weight) The values for µG and µR are based on serial tests and many years of industrial experience. However, due to particular environmental conditions, different results may occur. The values tR and tA refer to measured test values. Stopping distance (horizontal...

Stopping distance (vertical deployment) Vertical deployment speeds up the system until the element is triggered and braking is applied. The holding force is reduced by the weight. Speed at start of brake application Vbrake: Vbrake = vO + g x (tR + tA) = 2 m + 9.81 m x (0.06s + 0.01s) = 2.69 m s s s2 Braking distance SB : SB = Reaction distance + response distance SR: SR = vO x (tR + tA) + 1 x g x (tR + tA)2 = 2 m x(0.06s + 0.01s) + 1 s 2 Carriage of the Rail manufacturer Carriage of the Rail manufacturer Braking element UBPS Linear guide of the Rail manufacturer During installation of the...
