HepcoMotion SBD – Sealed Belt Driven Actuator

The SBD sealed belt driven unit incorporates a high strength steel reinforced tooth belt, with zero backlash and driving forces to 3300N. Hepco LBG precision caged linear ball guides provide dynamic load capacities to 52,100N. The unit is housed in a high strength aluminum beam and is completely enclosed with a very effective stainless steel band running along the length of the beam and kept in contact by a magnetic strip. This cover provides exceptional protection of the internal mechanism from dirt debris.

Description

Overview

The SBD sealed belt driven unit incorporates a high strength steel reinforced tooth belt, with zero backlash and driving forces to 3300N. Hepco LBG precision caged linear ball guides provide dynamic load capacities to 52,100N. The unit is housed in a high strength aluminum beam and is completely enclosed with a very effective stainless steel band running along the length of the beam and kept in contact by a magnetic strip. This cover provides exceptional protection of the internal mechanism from dirt debris.

Sealed Belt driven units, offered in standard and clean room configurations, come in three basic sizes, plus the addition of a New "High Stiffness" version SBD30-100XL, providing a higher level of performance in terms of load capacity and life than other comparable sized systems.

  • Three sizes, compact in construction SBD15-60, SBD20-80 and SBD30-100. (60, 80 and 100 relate to the width of the beam in mm).
  • Units are supplied in increments of 60mm (SBD20-80 and SBD15-60) and 80mm (SBD30-100) up to 6 meters long. Longer systems can be achieved by joining.
  • Shaft with fitted key; right, left, double and hollow shaft options
  • Limit switch and bracket options include mechanical and inductive versions
  • Internal buffers for end of stroke protection at each end
  • Speeds up to 4m/s
  • Pre-adjusted and pre-lubricated to offer practically maintenance-free operation
  • An access hole in the beam, closed off with a threaded plug, provides easy access for re-lubrication of the ball guide
A wide range of gearboxes, motors, motor connection kits, and drives are available. Other options and accessories include multi-axis mounting kits and tubular flanges.

SBD is compatible with the MCS line of aluminum framing.

Beam

The high strength anodized aluminum beam is supplied with T-slots for easy mounting. T-nuts, T-slot covers, mounting brackets and multi-axis connection brackets are available options.


Carriage Plate

The removable carriage plate is easy to detach, and can be rotated 180 degrees to change handing.


Clean Room Version

  • The clean room version of the SBD adds a vacuum connection, minimizing particle emissions. All external parts are anodized aluminum or stainless steel. The shaft is stainless steel, as is the threaded plug at the access hole in the beam.
  • SBD Clean room versions are certified by the Fraunhofer IPA Institute for use in clean room environments and meets air cleanliness class 3 according to ISO 14644-1.
  • Clean room version of the SBD is only available for sizes SBD20-80, SBD30-100, and SBD30-100XL.

SBD30-100XL

  • The SBD30-100XL unit has been designed for applications which require a stiffer beam than the standard SBD30-100 unit.
  • The New "High Stiffness" version is beneficial in systems with high loads and wide spans.
  • Stiffness of the SBD30-100XL is 104% higher than the standard version in the L1 condition.

Application Stories  
Questions

Can ball screws be used in vertical applications without back driving?

 
No. Without a brake motor, ball screws will always back drive.  

Can acme screws be used in vertical applications without back driving?

 
For vertical motion, lead screws can be self-locking so that even without brakes, dropping or drifting when motor power is removed or lost can be prevented. But the higher friction of a non-backdriving screw requires increased power to drive. The lead of the screw needs to be less than one-third of the minor diameter to not backdrive.  

What is the maximum recommended speed for DualVee guide wheel technology?

 
Speeds up to 5.5 meters per second.  

Can DualVee guide wheels be used in high temperature applications?

 
Specially designed guide wheels using all stainelss steel components, heat stabilized material, and with special grease (Krytox GPL 227) can operate up to 500°F.  

What is the coefficient of friction for DualVee guide wheel technology?

 
Between 0.005 — 0.02 when operated on DualVee track.  

What do the terms 'axial load' and 'radial load' refer to with regard to a bearing?

 

Axial Radial Definitions

Axial load is any load that is parallel to the axis of rotation of the bearing.
Radial load is any load that is perpendicular to the axis of rotation.

 



What are 'Pitch', 'Roll', and 'Yaw'?

 

Pitch describes a vehicle's tendency to rotate forward or backward.
Yaw describes a vehicle's tendency to turn left to right with respect to the direction of travel.
Roll describes a vehicle's tendency to rotate side to side with respect to the direction of travel.
