Image Credit: Branham, W.C. Inc.   Mechanical brakes are assemblies consisting of mechanical elements for the slowing or stopping of shafts in equipment drives. They use levers or linkages to transmit force from one point to another. Braking slows or stops the movement of the coupled shafts.   Applications   There are many applications for mechanical brakes. Some products are used in conveyors, bottle capping, and in wire, paper, foil, film, and textile...

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of mechanical brakes?
3 answers
Answers:
Yea, the leverage rates where wrong on a parking brake and the prototype hybrid vehicle rolled down hill into traffic and hit a curb fast and hard.
~Chase Norvich, Project Manager, Corvallis, OR
In the most time the thermal overload will not be sufficiently observed.
~Rainer S, Design Engineer, Wermelskirchen, Germany
Tear and wear

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
11 answers
Answers:
Compact, repeatable actuation, maintenance free
~Engineering, Design, Pinconning, MI
Lower maintenance. No cleaning and 10K miles between service.
~Chase Norvich, Project Manager, Corvallis, OR
Better friction coefficient, it lasts a long time, and excellent torque
~Franklin Montaluisa, Design Engineer, Quito, Equator
We need to have a proper system that we can use to develop brakes with specific predefined characteristics and friction properties. I find that it is a rather hit and miss affair to create the correct brake linings for our applications.
~Production Engineer, Blackheath, South Africa
To be involved earlier into the design of the customer. The facilities of the brakes can be better placed.
~Rainer S, Design Engineer, Wermelskirchen, Germany
Disc brakes Master cylinders Rotors Balance bars Pipes and fittings Calipers
~Dan Rodrigues, Student, Aracaju/Sergipe, Brazil
Longer lasting pads and discs More mounting options
~Tom S, Facilities Manager, Onoway, Canada
High frequency of use with low maintenance.
~Arthur Davies, Technical services engineer, Wadeville, South Africa
Able to adapt and easy to repair.
~Maintenance/Facilities Management, Batavia, IL
Easier access to information.
~Trevor S, Engineering Consultant, Fredericton, Canada
Effective braking system.
~Yaqub Adamu, Research & Development, Katsina, Nigeria

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of mechanical brakes?
6 answers
Answers:
Leverage and motion rates are routinely screwed up or not computed by those who select them. This is the single most important thing to get right. If you don't they are not going to work.
~Chase Norvich, Project Manager, Corvallis, OR
The correct mounting of the system's components are so critical. The selection is the stage of process when you will determine the success or failure of the system. Check the size, fastening methods, brackets and others.
~Dan Rodrigues, Student, Aracaju/Sergipe, Brazil
Do not be too influenced by the price - it is a small component of the final vehicle costs.
~Production Engineer, Blackheath, South Africa
Check the function of the braking system: static brake / dynamic brake Fix the required torque In case of dynamic application: how long is the slipping time, range of speed, inertia. Frequency of switching the brake. What type of actuation would be preferred (hydraulic, pneumatic, electromagnetic...) Contact a brake manufacturer who can help you to choice the correct size of the brake
~Rainer S, Design Engineer, Wermelskirchen, Germany
Have them checked every 6 mos.
~Technical Support, Omaha, NE
Always keep checking.
~Yaqub Adamu, Research & Development, Katsina, Nigeria

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using mechanical brakes?
10 answers
Answers:
Spring applied brakes can fulfill safety functions without external energy supply. Multiplate brakes reduce the clearance for the drive. To avoid uncontrolled movements of a drive a brake is always necessary. Using a dynamic brake saves oversizing of the drive motor, reduces costs.
~Rainer S, Design Engineer, Wermelskirchen, Germany
Don't go on price alone, a cheap liner is probably not cost effective. Go for an over sized brake if you have the space.
~Tom S, Facilities Manager, Onoway, Canada
Do proper road tests of vehicles to check that the dynamometer results can be replicated on the road.
~Production Engineer, Blackheath, South Africa
Deal with engineers at the manufacturers, not vendors - they don't have the technical expertise.
~Trevor S, Engineering Consultant, Fredericton, Canada
Pay attention on the correct specification of your system, and take considerations about the environment where the components will work.
~Dan Rodrigues, Student, Aracaju/Sergipe, Brazil
Go hydraulic for anything other than a parking brake.
~Chase Norvich, Project Manager, Corvallis, OR
Select device as per requirement of your RPM, Torque
~R Subash B, Engineer, Chennai, India
We are still in the evaluation phase.
~Imad Handy, Engineer, Germany
Research different brands.
~Maintenance/Facilities Management, Batavia, IL
Frequent checking
~Yaqub Adamu, Research & Development, Katsina, Nigeria
