Hello all,
I'm after some advice...
I'm a process engineer in a welding / assembly shop with over a thousand welding and handling robots. Currently there is limited automatic cycle time recording function in the jig & robot cells which means every time we launch a new product, there are...
Hi all,
I've seen, a few times, the use of a very small spur gear used to dampen the movement of a rack it's engaged to. I imagine the gear has a very tightly fitting rubber bushing or similar which creates high friction as it turns. I'm currently looking for one for a project where a spring...
Hi all,
I'm currently working on a design which uses a geared motor which is linked directly to a rack and pinion system. The motor I'm looking at has a Ø6mm shaft with a flat spot 5.5mm from one side (making it a D shape). I need a pinion to fit to the motor shaft with little chance of...
Hi all,
I'm currently designing a system which requires a electronic linear actuator on a reciprocating cycle. I have been informed it would be relatively easy to use a latching DPDT relay with 2 micro switches positioned at each end of the actuator's stroke. However, I require a time delay at...
Has anyone had any success with mounting two Peltier modules together in order to achieve higher temperatures on the hot side and lower temperatures on the cold?
I'm currently designing a combined heating and cooling system which will ultimately be used for a batch pasteurisation process. The...
Hi all,
I'm somewhat of a novice with electronics but I am currently designing a system which needs to heat 2l of liquid up to 64°C for a short time (around 2 min) and then quickly cool it to below 7°C.
Is it possibe to use peltier modules for both aspects of the system, heating first and...
Hi all,
I'm currently designing a system where by the following would be very useful:
A pivot which remains in a "locked" position until a torque setting is over come, releasing the lock allowing the pivot to move freely. (See attached image).
Has anyone come across anything like this...
After reading a previous post on this forum I now understand that the way to go is to start with a solid block, cut in the cavities, flip the part over and shell.
I need to design a tray which has a constant base (stack one way and nest the other) but the cavities must be easily changed (this...
I have recently started working at a plastics fabrication company as a trainee CAD / CAM designer. The line bending process is widely used with in the company for parts such as polycarbonate and acrylic machine guards etc. Up to now the CAD / CAM designer has been modeling the part in solidworks...
