The lifting principle of the worm gear screw lift
It consists of a worm gear reducer and a lifting screw. Its deceleration component is a worm drive, and the worm is used to drive the worm gear to achieve deceleration. The center of the worm gear is an internal thread structure, which is equivalent to the nut of the lifting screw and matches the lifting screw. The lifting speed is equal to the worm input speed divided by the reduction ratio of the worm gear, and then multiplied by the pitch of the lifting screw. Due to its structure, this kind of worm gear screw lift is generally lubricated with grease. Some series are lubricated with lubricating oil. They have the advantages of longer life and stable operation than the grease-lubricated series.
During use, the series of screw lifts have the advantages of low noise, smooth transmission, and flexible use. In order to ensure safety during use, the lift is equipped with an automatic locking function. When there is a problem with the operation of the equipment, the lift will It can self-lock and stop movement, ensuring the safety of the production environment and production personnel to a certain extent.
Shanghai Nuoguang produces worm gear screw lifts: specifications, models:,.,,,,,,,large super lift:,.,,,,,,seven types, high input speed r/, large lifting speed. /. There are different structural types and assembly methods. It is widely used in machinery, metallurgical construction, water conservancy equipment and other industries. Lift carrying capacity, the lift device can be self-locking. It has many functions such as lifting, lowering, pushing with auxiliary parts, turning over and various height and position adjustments.
Please confirm the following points before purchasing
1. Select the model: Basic type: type with hand wheel, (can load left and right)
Basic type, type with hand wheel (can load left and right)
2. Select the reduction ratio: :, :, :. Choose any one of the three speed ratios: : is the fastest for lifting and : is the slowest.
3. Confirm the screw head: choose one of the four types of heads: flange type, cylindrical type, thread type, and flat head type.
4. Confirm the length of the screw rod: The price within the stroke is the basic price. The length can be customized according to the customer's requirements. It can be lengthened or shortened. The screw rod specification is R*,. The screw rod specification is R*)
Lift Selection instructions
Find out the required lift model based on the screw stroke and lifting load, then check the lifting force and lifting speed tables to check whether the lifting speed meets the requirements.
Example: It is known that the lifting load is =, the screw stroke =, the lifting speed =./, try to find the required lift.
According to =, screw stroke =, select the lift. Then check the lifting force and lifting speed meter to check that the lifting speed is only allowed to be ./ under load, and only reselect a larger model of lift. Then look at the lifting and lifting force speed tables to find out that the allowed lifting speed under load is ./, which meets the requirements.
Note
When the pressure load decreases, the lifting height can be increased accordingly
When lifting different loads, the allowable torque, power, and speed are also different, and different working durations The high power of the rate is also different
. The structure is lubricated with grease. As the temperature rises, lubricant should be replenished in time
. The power in the table is the parameter under the condition of grease lubrication
. The lubricant should be replaced in time during work
. Working environment temperature: ℃~+℃
. It can generally self-lock in a static state.
