Lightweight CAD data format - let go of your design ideas (3)

<br> <br> format standard format and the use of lightweight browser technology is a CAD vendor advantages: It can be integrated with the original CAD software, and bring a wealth of product information, enhanced graphics capabilities. Therefore, for those user groups who have no choice but to collaborate with various CAD software in the design process, the CAD vendor's format brings the best results. On the other hand, in terms of collaboration for marketing or sales purposes, companies can provide the best service by leveraging a format with extensive receiving capabilities.

Mackrell said: "If you are just using the browsing tool to view the data, you can implement a simplified browsing, although you still want to be able to rotate the module and view it in 3D. But when you need to extract a lot of engineering data from the browser, such as When you have accurate product description data, you need a more powerful browsing tool that is more powerful."

He pointed out: Today, most formats and browsers combine rotation, scaling, and even cross-section functions, so potential users need to pay close attention to some advanced features when choosing 3D format, such as its access level to PMI data. In some scenarios, an important factor to consider is how well a particular format is combined with file standards or with business software. Finally, the vendor's overall solution needs to be taken into account, and these options may include workflow applications or information security.

Gisela Wilson, director of IDC research at IT analysts, points out that whether CAD software vendors can increase their market share by leveraging their competitors is largely related to the popularity of their lightweight CAD formats. She believes that the large-scale design system suppliers, such as Autodesk's business scope is so extensive, mainly due to the strong user base of its CAD software, and Adobe's success lies in the popularity of its Reader products. Still, Wilson said end-user companies often need to support multiple formats because each CAD vendor's lightweight browsing software may only be suitable for a particular CAD product, and users are likely to need a wide range of design collaborations across geographies. Even engineering collaboration across borders. At that time, a single browsing software could not meet the needs of everyone.

Best Practices Mackrell believes that if multiple formats must be used, an important best practice is to ensure that all lightweight files are fully synchronized with the main CAD model. Companies often achieve this through a product data management system.

Vendors are adding new features to their formats, eliminating the weaknesses of previous products. For example, Adobe acquired CAD and software provider Trade and Technologies France (TTF) in April last year, and added TTF technology to its Acrobat version 8. By April of this year, the latest version will enhance the conversion and compression of multiple CAD formats. Features.

If multiple formats must be used, an important best practice is to ensure that all lightweight files are fully synchronized with the master CAD model.

According to Rak Bhalla, Manufacturing Marketing Manager, Adobe Knowledge Worker Business Unit, TTF's technology has at least the following advantages to help users solve real-world problems. First, it provides users with the option to use the TTF's PRC format, and the compression ratio achieved under Acrobat 3D will be larger, resulting in smaller files. Secondly, TTF's CAD transfer technology will enable the next version of Acrobat 3D to have a more intelligent PMI data layering, so that users can switch the data display freely.

At the same time, the CAD vendor format has become more open. Mackrell pointed out that the JT format from PLM provider UGS is widely used in enterprises. UGS even announced the introduction of JT Open, which will allow other CAD vendors to have more comprehensive support for JT.

Bearing Housing

Bearing housings are modular assemblies designed to make it easy to install bearings and shafts, while protecting bearings, extending their operating life and simplifying maintenance.

Housings are available in many sizes, and generally fall into five standard categories: split plummer (or pillow) block housings, non-split plummer block housings, flanged housings, take-up housings and two-bearing housings. These products can be designed to meet specific duty requirements such as load, speed and operating environmental conditions.

Non-standard bearing housing designs can also be supplied to particular customer requirements: for example, where special shaft centre heights, unusual sealing arrangements or non-standard materials of construction may be specified.

If ease of installation and maintenance are prime considerations, then split plummer block housings are an excellent choice as they not only accommodate pre-assembled shafts, but also simplify bearing inspections and maintenance as the shaft does not need to be disassembled. These units are designed for self-aligning ball bearings, spherical roller bearings and CARB toroidal roller bearings. Non-split plummer block housings are preferred when there are heavy loads acting in a direction other than toward the support surface. They are also used when the housing has to be mounted from the end of the shaft.

We have specialized in producing US/EURO standard bearing housings more than 10 years, could help to design the bearing housing or produce the bearing housing according to your requirements. (OEM accepted)
