Geared Cam Limit Switches Serie 51/51 DZ

Product catalog summary
Overview
The document is a technical catalogue for the Geared Cam Limit Switches Series 51 and 51 DZ, dated October 2008. It provides detailed specifications, construction details, and operational guidelines for these mechanical switching devices, which are used to limit angles or routes indirectly via shaft rotation measurements.
Specifications
- The switches feature patented planetary gearing made of high-quality synthetic materials, ensuring low friction and maintenance-free operation.
- Housing options include plastic or aluminum cast, with protection ratings of IP00/IP20, IP65, or IP66.
- Operating temperature ranges from -40°C to +80°C.
- The switches comply with EN ISO 9001 quality standards.
Construction and Features
- The switches consist of a gearbox and switch housed together, with torque transferred to cam discs.
- Differential tooth gear construction allows for a gear reduction of 69.98 per gear step, improving switching accuracy by a factor of 16.
- Modular design ensures economical and flexible manufacturing.
- The switches offer a patented block adjustment feature, allowing simultaneous adjustment of all contacts without altering individual switching points.
Applications
- Commonly used in crane hoisting gear to limit hook travel.
- Suitable for applications requiring positive opening switching contacts as per EN 60947, part 5-1, IEC 947-5-1.
Advantages
- Large cam disc diameter for good adjustability and high switching point repeat accuracy.
- The differential tooth gear reduces the assembly length by approximately 19 mm compared to standard planetary gears.
Limitations
- The simple block adjustment feature of the normal series 51 is not available in the differential tooth gear execution.
- Potentiometer coupling cannot be mounted on this gear execution.
Additional Features
- Options for inserted drive shafts, potentiometer drives, indicating plates, anti-condensation heaters, and pulse transmitters.
- Motor-driven block adjustment and variants for increased requirements according to BGV C1 (stage technology) are available.
Procedures
The document outlines the block adjustment procedure, which is standard in the planetary gear construction. This allows for a block adjustment in addition to individual contact adjustments from the usable revolution 17.5 (gear size 2). The final gear stage includes an adjusting worm, colored black, for common adjustment of all cam discs without altering the relative adjustments of individual contacts.
Standards and Recommendations
It is recommended to use only normally closed contacts from gear size 6 due to the slow actuation speed of switching contacts caused by high gear reductions. Before using analog feedback systems, consultation with the technical department is advised.
Ordering Information
For standard geared switches, necessary ordering data includes series, type, construction, and protection level. Additional data for special types and options include effective cam angle, PTC heater supply voltage, and sensor data sheets.
Tables and Data
The document includes tables detailing gear data for Series 51 and 51 DZ, including gear size, nominal revolutions, usable revolutions, gear ratio, and maximum drive speed. It also provides a table of contact types, materials, and electrical data.
Cam Discs
Standard cam discs are equipped with 15° contact cams, with options for 40° cams at no extra charge. Special cam angles can be manufactured at an extra charge. The usable number of revolutions of the drive shaft enabled by a cam disc is calculated based on the effective cam angle and gear reduction.
Drive Mechanism
The drive can be radial, such as through a chain drive, or axial, such as through an elastic coupling.
Drive Specifications
The document outlines the specifications for the drive mechanisms of the Geared Cam Limit Switches Series 51 / 51 DZ. It emphasizes the importance of adhering to the maximum permissible radial load on the input shaft, especially when using chain, toothed wheel, or synchronous belt drives. The ideal drive is described as one that uses a torsionally stiff, flexible coupling to balance misalignment and axial displacement.
Housing Variants
The document details various housing options for the switches, including component housings with protection ratings of IP20/IP00, aluminium protective housings with IP65, and plastic housings with IP66. Each housing type is designed for specific environmental conditions and mechanical requirements, with modular designs allowing for customization and extension.
Aluminium Housing (IP65)
This housing is suitable for harsh environments and is designed to accommodate large and heavy encoders. It features centering lugs for encoders and is available in different sizes to fit various components.
Plastic Housing (IP66)
Made from glass fibre reinforced polycarbonate, this housing offers high dimensional stability and protection over a wide temperature range. It is modular and can be extended with intermediate pieces to suit specific needs.
Technical Data and Options
The document includes technical specifications such as maximum service speed, twisting angles, and dimensions for various configurations. It also mentions optional features like potentiometer drives and indicating plates for block adjustment.
