简体中文 Have you ever seen a conveyor line that jumps from side to side? Obviously only a motor, but can take the material to run forwards and backwards, like magic! Today we peel off the shell of this black technology, talk about theSingle motor-driven bi-directional conveyor lineThe doorway to the -Saves electricity bills, space, and maintenance man's tearsThe ruthless character!
🔧 I. Core principle: How can a motor take two directions?
To put it bluntly.Cogs Bite Cogs "Betrayal Game"! Come see the tawdry operation of a certain patent:
- The centre shaft is the "second passer".: The motor first drives the intermediate shaft sprocket (Fig. 1), which has sprockets and gears hanging from each end of the shaft.
- forward drive: Sprocket → chain → left roller (carrying the belt positively)
- Reverse drive: Gear → Occlusion of right gear → Right drum (forced to rotate backwards)
You think about it: isn't it like drawing a circle with your left hand and a square with your right? One instruction for two things! What's even better.The distance between the two belts is pressed to 3mmIt's thinner than a mobile phone, and the use of space is absolute!
⚙️ Second, the black technology of anti-detachment: don't let the chain "swing".
The biggest pain point of a two-way run isLoose chain build-up during reversalWhat to do? The engineers offered two major assets:
| programme | Unidirectional bearings | ratchet mechanism |
|---|---|---|
| theory | Inner ring jammed outer ring reverse idling | Anti-backlash pawl groove |
| (manufacturing, production etc) costs | 150-300 RMB/pc | 80-200 RMB/set |
| resistance | Fear of dust (to be sealed) | Easily chipped on impact (requires regular jaw changes) |
| Applicable Scenarios | Automotive assembly line (precision needs) | Courier sorting (low-cost preferred) |
The bloody history of a new energy plant: when no anti-detachment mechanism is installed3 emergency stops per hourAfter adding a double row of one-way bearings--9 months with 0 faults! - I don't know! It's worth the money, isn't it?
💰 三、省钱妙招：单电机究竟多划算？
Straight up hardcore comparisons! Take the 20 metre line for example:
| money-spinning project | Dual Motor Solutions | Single Motor Solutions | How much do you save? |
|---|---|---|---|
| Procurement of equipment | 240,000 | 180,000 | 25% |
| annual electricity bill | 36,000 | 21,000 | 42% |
| 5-year maintenance fee | 80,000 | 45,000 | 44% |
⚠️ Note: Single Motor ProgrammeSlightly higher gear set maintenance costs(about $5,000 more/year), but overall hangs on to the dual motor
🚚 IV. Practical god operations: these industries steal the show
▶Automotive welding workshop(a German brand)
- sore point: White body transit requires frequent forward and reverse rotation, with an average of seven chain strikes per month
- remould::
- Forward teeth in the upper half of the main wheel + reverse teeth in the lower half (Patent Fig. 4)
- Retrofitting of hydraulic damping buffers
- effect: Carrying an impact force of 18kN.Slope Friction Torque Drop 40%
▶Milk Tea Ingredients Factory(Don't laugh, it's true!)
Sugar tank conveyor belts were often clogged and workers were forced to manually reverse them - annual maintenance costs of 370,000 dollars! After changing to a single motor + magnetic unlocking handle:
- Emergency unlock <3 seconds
- Payback period 5.2 months(The boss gave the engineer two cases of milk tea...)
🌟 EXCLUSIVE VIEW: 3 Trends That the Future is Here
- Ceramic bearing dry turned steel: Silicon nitride ceramic wedges for a laboratory.Spinning up to 8000rpm.--Lithium battery pole piece high-speed transport is saved!
- Intelligent prejudgement system: Monitoring of current ripple, bearing wear2 weeks advance warning"Better than a master's ears.
- Quick release design: Referring to Patent 39385374, Non-destructive splitting of the first/second outer ring.Replacement of efficiency lift 70%
Final stormy words.Don't listen to manufacturers who say "the more complex the more advanced"!A really good design is one that "makes way" for impacts (e.g., hydraulic cushioning), rather than carrying them hard. Like the old engineer said."The essence of anti-shedding is not reinforcement, it's finding an outlet for the energy.". Next time you see a single motor with two-way wiring, remember to touch the gears - there's a money-saving philosophy of manufacturing hidden there!
