Ball Screw Support Standards - Lishui Jie Sheng Transmission brings you to the heart of precision drives
With the mission of "Driving the Future with Precision", Lishui Jiesheng Transmission is committed to creating reliable transmission solutions for customers around the world. As the "heart part" of mechanical transmission, the quality of ball screw support base directly determines the stability, precision and life of equipment operation. The following seven core dimensions, to take you in-depth understanding of the quality of high-performance ball screw support seat code, to unveil the mystery of precision transmission.
I. Material and treatment: the basis for durability
1. Material selection
Bearing steel: It is the most commonly used material, like a solid cornerstone, with high hardness and wear resistance after heat treatment, it can withstand frequent friction and load, and is widely used in high-precision scenarios such as CNC machine tools.
Stainless steel: like a self-contained "shield", excellent corrosion resistance, suitable for medical equipment, food machinery and other wet or corrosive substances in the environment, not easy to rust damage.
Aluminum alloy: light as a "feather", weighing only one-third of steel parts, suitable for weight-sensitive equipment, such as collaborative robots, but requires special design to ensure strength.
2. Heat treatment process
Through quenching and aging treatment, the material is made "both inside and outside": quenching makes the surface hard and wear-resistant, while aging treatment removes internal stresses, ensuring dimensional stability after prolonged use and no easy deformation.
II. Machining precision: micron-level strict requirements
1. Dimensional and shape accuracy
The hole of the support seat should be round enough, the end surface should be flat and vertical, and the installation base surface should be smooth, just like a precision "mold", the error is controlled in a few micrometers (equivalent to one-tenth of a hair), otherwise it will affect the positioning accuracy of the equipment.
For example, the hole roundness error of the high-precision support base is no more than 3 microns, which ensures a close fit with the ball screw and smooth operation without any jamming.
2. Tightness of fit
The fit of the support base with ball screws, bearings and other components should be just right: there is a small gap (5-15 microns) between the shaft holes to ensure flexible rotation without shaking; the bearing preload should be uniform to avoid uneven force resulting in loss of precision.
Third, bearing capacity: to deal with different loads of "muscle power"
1. Dynamic bearing
Refers to the maximum force that the support base can withstand in continuous motion. Different equipment needs are different: small automation equipment may only need a few tens of Niu bearing capacity, while large machine tools need several hundred Niu or even higher. A quality support seat will be designed according to the actual load to ensure long-term operation without damage.
2. Static load bearing
Even if the equipment is stationary, the support base needs to withstand sudden impacts. For example, when the equipment encounters an accidental collision, the support seat should be strong enough not to be deformed due to instantaneous overload, to protect the safety of the equipment.
IV. Long-term stability: time-tested "endurance"
1. Resistance to thermal deformation
Heat will be generated when the equipment is running, the high-quality support seat selects materials with low coefficient of thermal expansion and reserve expansion gap, even if the temperature rises by 20 ℃, the axial displacement can be guaranteed to be extremely small (no more than 10 microns), to avoid the precision being affected by thermal expansion and contraction.
2. Wear resistance
After long-term use (e.g. 1000 hours), the bearing and mating surface of the support seat should have very slight wear (the depth of wear does not exceed 2 microns), just like "wear-resistant tires", to ensure that the precision is still reliable after long-term use.
V. Environmental adaptability: "Survivability" to cope with complex scenarios
1. Corrosion resistance
In wet or chemical environments, the support base needs to be corrosion-resistant. Stainless steel or special plating (such as galvanized) can effectively resist corrosion, after the salt spray test (simulated humid environment), hundreds or even thousands of hours after the rust is still not obvious.
2. Resistance to vibration and shock
Vibration and shock are inevitable in industrial environments, high-quality support base after special design (such as the use of shock-absorbing materials, optimize the structure), can be quickly restored to stability after strong vibration or shock, with minimal loss of precision.
VI. Installation compatibility: "tacit understanding" in synergy with the system
1. Interface standardization
The size of the support base, mounting hole position, etc. should be in line with industry standards, and can work seamlessly with the mainstream brands of ball screws, sliders and other components, like "universal parts", to facilitate customers to replace or upgrade the equipment without the need to re-design.
2. Pre-mounting accuracy
Before leaving the factory, the support base will be pre-installed and debugged bearings and other components to ensure that the axial clearance is almost zero, so that customers can quickly install it when they get it, reducing debugging time and improving efficiency.
Noise and energy efficiency: the "comfort" of industrial scenarios.
1. Low noise operation
By optimizing the bearing design and using quiet materials (such as nylon cages), the support base operates with very low noise (no more than 55 decibels when unloaded, which is equivalent to the sound of a normal conversation), which reduces the noise pollution in the industrial environment.
2. Efficient transmission
High-quality support seat has small friction coefficient and high transmission efficiency, just like "smooth gear", which can reduce energy loss, and the positioning accuracy can be up to 0.005 mm when cooperating with servo motor, which is both energy-saving and accurate.
