Features of slow speed motor

1. High strength alloy steel gear surface and thrust block specially designed for plastic screw extruder
2. Noise Level: Low type 65-80 Db, Smooth and stable in run
3. Compact, high in bearing capacity, stable in transmission, high efficiency
4. By forced lubrication and cooling system.
5. Bearing: Chinese famous brand ZWZ bearing. But other brand bearing is a aviable if need.
6. Unique modular design easy for cross country production, low stock, short delivery time.
7.The seal of output shaft part adopts double oil seal with perfect oil leaking resistance.Reliable sealing and more widely applicable to industry.

Assembly Style

1) Verify transmitted power. For slow speed motor, the behavior coefficient has been considered in the input powers and the output torques in the Table, therefore it can be selected directly from Table. The output torque in the table is also the main basis to make selection. If the normal driving ratio in the table couldn’t meet the requirement, please contact with our company.
2) Verify thermal power. For slow speed motor , make selection as per the notes on the Table.
3) Verify assembly and connection sizes. If the sizes you need is different from those in the table, please contact our company.
4) Verify radial force of shaft extension. If the input shaft adopts connection style with pulley which can cause added radial force, it should confirm that the radial force at the middle of the input shaft extension if it is less than 125, here T1 means the input torque. If it is not enough, please contact with our company.

Application and Maintenance of slow

1) When lifting the slow speed motor, the ring screw should be used.
2) Take care to prevent moisture when the slow speed motor is in transportation or storage. If do not assemble in half a year after it is arrived, the exposure surface should be coated with antirust oil.
3) The base to assemble the slow speed motor should be plain with enough strength and rigidity. Under circumstance the anchor bolts are evenly tightened it should ensure that the screw rod inserted into the output shaft should be rotated freely without blockage. The assembling error of the coupler should do not excess its allowed tolerance so as to avoid from added force and to cut down the life of the bearings.
4) The slow speed motor should pass through strict test running inspection before they are delivered. Only all index are in according to the requirement, can they be put into use directly after delivery. Before application, it should be filled with mid-extreme pressure gear oil N220 up to the upper limit of the oil mark (N150 if circulation pump lubrication is used.) if the reducer has pipe style oil cooler, the run the reducer under no-load for a short period of time after oil is filled, then fill oil again up to the upper limit of the oil mark.
5) For the slow speed motor with motor oil pump, before adding load, it should switch on the oil pump of the motor to run the gearbox under no-load for a short period of time so as to facilitate full lubricant points.
6) Replace oil when the slow speed motor is initially running for 300 hours, and change oil once for every 3000-4000 running hours thereafter. The maximum interval between oil replacements should be no longer than 18 months. When replacing, first clean box body, oil filter and oil discharge screw plug.

Packaging of slow speed motor

We have flexible packing method for different kinds of gearbox:
Small size: standard export packing (carton and pallet)
Big size: wood carton or non-wood packing material carton, or according to the customer's requirements .

Shipping of slow speed motor

1) Less than 45 KGS, we will send by express. ( Door to Door, Convenient )
2) Between 45 - 200 KGS, we will send by air transport. ( Fastest and safest, but expensive )
3) More than 200 KGS, we will send by sea. ( Cheapest, but long time )
