Linispeed Jack
Words
Q1 | What does low height design mean? |
---|---|
A1 | Conventional Jacks mount ball nut on the top of the worm wheel. |
Q2 | Is the speed of 200mm/s faster than conventional Jacks? |
A2 | Conventional Jacks could only operate around maximum 125mm/s. |
Q3 | Why possible high-speed operation? |
A3 | Comparing with conventional Jacks, Lini Speed Jack enlarges the distance between cores. |
Q4 | Why the percent ED of Lini Speed Jack can be raised? |
A4 | Same reason as the previous question, Lini Speed Jack has less heat generation and less downtime, contributing to higher percent ED. |
Q5 | Why is the service life of Lini Speed Jack longer? |
A5 | The ball screw used in Lini Speed Jack has higher function than those used in conventional Jacks. |
Q6 | What's high function ball screw? |
A6 | It's our company secret and we can't give details. We improved ball screw materials to enable more than 10 times longer expected travel distance than general ball screw. |
Q7 | Does conventional Jack have thrust limit? |
A7 | The output shaft allowable torque falls down as worm gear input speed goes up. |
Q8 | Why the no-load idling torque of Lini Speed Jack is large? |
A8 | There are two reasons. First, comparing with conventional Jacks, Lini Speed Jack enlarges the distance between worm cores, as a result, the resistance of both lubrication stirring and oil seal sliding gets bigger. |
Q9 | Is synchronized operation possible? |
A9 | The synchronized operation is possible by combined use with coupling and MD gear box. |
Q10 | Does Lini Speed Jack have self-lock function? |
A10 | No, it doesn't. |
Q11 | Why the bellow of Lini Speed Jack is MTO item? |
A11 | Under high-speed operation, standard bellows may break as they are unable to cope with the air flow inside of Lini Speed Jack. |
Q12 | Can an oil lubrication package be made upon request? |
A12 | The oil lubrication of Lini Speed Jack gear is standard. |
Q13 | Is grease lubrication gear type available? |
A13 | Yes, but it cannot be operated at maximum speed and allowable frequency given the degraded lubricating property. |
Q14 | Is clean room specification available? |
A14 | We can apply low-dust grease to screw shaft or offer raydent treatment, input shaft anti-rust coating. |
Q15 | How to read the percent ED chart for allowable load hourly rate? |
A15 | Choose the reference chart based on the model No. and ambient temperature. |
Q16 | Is it possible to mount servo motor to flange ? |
A16 | It's possible for servo motor of size176, please consult us for detail. |
