Vis boul yo se eleman transmisyon ki pi souvan itilize nan zouti machin ak machin presizyon. Fonksyon prensipal li se konvèti mouvman wotasyon an mouvman lineyè, oswa konvèti koupl nan fòs repetitif axial. An menm tan an, li tou gen karakteristik segondè presizyon, revèsibbilite ak efikasite segondè.
Eksantrisite: refere a devyasyon sant ant bò fiks ak bò sipò.
Inclination: In addition to eccentricity, the installation error caused by the parallel error (up, down, left, and right) or vertical error of the screw nut mounting part between the screw shaft and the guide (LM guide, etc.).
Installation accuracy reference: Refer to the table for the reference value of the installation accuracy of the ball screw. The data in the table is for reference only. Please minimize installation errors. The installation accuracy of the motor support and coupling affects the walking and positioning accuracy of the workbench, so attention should be paid to the ball screw.
Unpacking: Be careful not to hit the nut and end thread. When disassembling the nut, you can manually rotate the nut from one end of the effective thread to the other end. Check whether the resistance is consistent and whether there is obvious bending. Be careful not to disengage the nut screw from the effective thread. Wipe off the surface anti-rust oil and apply lubricating oil.
Maintenance: When the linear speed is less than or equal to 30m/min, grease can be used for lubrication. According to the working conditions, grease should be injected every 300 to 600 working hours. It is recommended that oil lubrication be 30-60m/min, ak lwil oliv fòse lubrification farinay ka konsidere kòm 60-100m/min. Li rekòmande pou bay lòd pou yon vis kre epi adopte fòse refwadisman ak wilaj. Kenbe anviwònman k ap travay la pwòp epi pa kite pousyè ak lòt enpurte antre nan kous la oswa nwa. Si sitiyasyon an pa bon, konsidere ajoute yon kouvèti pwoteksyon nan vis yo.
Ball screws are usually used where precise positioning is required. The ball screw has high mechanical efficiency, low transmission torque and almost zero axial clearance, making it an important device in tool positioning and aileron drive applications. However, the resistance and heat generated by continuous operation may cause large friction and positioning errors. Increasing the design coefficient of the ball screw friction will also increase the torque, which in turn affects the positioning accuracy. When the ball is pressed between the ball screw nut and the screw shaft, the wedge effect is a potential source of friction. When rotating in the forward direction, the ball is usually pressed on the nut; on the contrary, the ball is squeezed on the screw shaft. Since the sliding friction coefficient is much larger than the rolling friction coefficient ({{0}}.1-0.3 when there is no movement, 0.001-0.003 when rolling), the wedge effect greatly increases the torque.
Ball screw drive has the following advantages:
①Segondè efikasite transmisyon. Efikasite transmisyon transmisyon vis boul se jeneralman 20.92-10 pousan, ak efikasite transmisyon nan transmisyon òdinè vis glisman se 20.20-0.40.
②Segondè presizyon transmisyon, mouvman ki estab epi pa gen okenn fenomèn rale. Kondwi vis boul la se fondamantalman woule friksyon, ak ti rezistans friksyon, ak rezistans friksyon an gen prèske pa gen anyen fè ak vitès mouvman an.
③Kouri nan ranvèse angrenaj san ralenti. Apre vis boul la ak nwa yo pre-sere, clearance axial la ka elimine. Nan fason sa a, pa gen okenn zòn mouri nan direksyon opoze a, ak presizyon ak frigidité nan transmisyon axial la amelyore.
④Li revèsib. Paske pèt friksyon vis boul la piti, li ka konvèti soti nan yon mouvman rotary nan yon mouvman lineyè, epi li kapab tou konvèti soti nan yon mouvman lineyè nan yon mouvman rotary. Tou de vis la plon ak nwa a ka itilize kòm yon kondwi oswa disip.
⑤Long sèvis lavi. Akòz ti pèt friksyon woule friksyon, lavi sèvis la long.
As a precise and labor-saving transmission mechanism, the ball screw is widely used in precision machine tools and CNC machine tools due to the above advantages.
