Planetary roller screws ISR | Trục vít con lăn ISR Ewellix được sử dụng rộng rãi trong nhiều ứng dụng khác nhau, yêu cầu độ chính xác cao và tải trọng lớn.
The inverted planetary roller screw provides powerful electro– mechanical actuation when compactness, low torque and high load capabilities are prerequisites. The rollers, synchronized with the threaded shaft through toothed rings, translate along the nut. The application loads acting on the translating push tube transit through the planetary rollers to the rotating shaft or nut. Toothed rings and guides provide the rolling motion and the even circumferential position of the rollers, for near-perfect load distribution. The rings and guides also avoid any parasitic friction between the rollers.
Đặc tính trục vít con lăn hành tinh ISR
Planetary roller screw concept without recirculation
Leads as small as 2,4 mm, combined with the benefits of the robust planetary roller screw design
Either nut or shaft can be driven, the non–rotating and translating component acting directly as the push tube
Custom screw-to-motor attachments for easy integration
Standard delivery without wipers
High speed and acceleration capability, similar to planetary roller screws
Two versions are available: ISR with axial play
IBR without backlash
Flexible production equipment
Small lead associated to a relatively large nominal nut diameter
Ứng dụng
The compact inverted roller screw, incorporated within an electro–mechanical actuator, can replace hydraulic or pneumatic actuation systems typically found in the following applications:
• Factory automation (for example, automotive assembly lines)
• Welding guns
• Portable high power tools
• Oil and gas subsea equipment
• Aerospace actuators
