- Rack parameter selectionRack parameter selection(1) Whether the runout, full tooth depth, common normal line and tooth direction of the gear are qualified, and whether the pitch error is out of tolerance.(2) Whether the installation distance of gear and rack is appropriate after installation.(3) The meshing clearance of ra
- AlveolusAlveolusCogging is the concave part between the teeth of a gear.The space between two adjacent teeth on a gear is called a cog or a cog. The size of the tooth slot is represented by the slot width, which can be divided into two types: the end slot width and the normal slot width.(1) End slot width (
- Worm gear mechanismWorm gear mechanism is often used to transmit the motion and power between two staggered axes. Worm gear and worm are equal to gear and rack in their middle plane, and worm is similar to screw.Basic parametersModulus m, pressure angle, worm diameter coefficient Q, lead angle, worm head number, worm
- Use of pressure angleUse of pressure angleWhether in plane transmission or in gear transmission, the pressure angle can be used as a standard to judge the transmission performance of the transmission mechanism. The smaller the pressure angle is, the greater the component force of the force along the speed direction is,
- Hydraulic clutchHydraulic clutchCompared with mechanical clutch, hydraulic clutch uses fluid (generally oil) as transmission medium. In addition to various changes in transmission characteristics, it mainly absorbs the vibration and impact caused by the rotation of driving shaft and driven shaft.The structure of th
- Technical requirements for taper sleeve processingTechnical requirements for taper sleeve processing:1. Forging: 224x210x50 annealed.2. Plane: 214x2005x40.5.3. Grinding: rough grinding six sides, deburring.4. Pliers: scribe.5. Boring: coordinate boring 2x14 pre holes.6. Electric: electric pulse cavity.7. Mo: 200x200 succeeded.8. Pliers: deburring a
- Advantages of rack and pinion driveCompared with belt drive, rack and pinion drive has the following advantages:(1) Transmission power, the characteristics of efficient gear transmission. Gear transmission is used to transmit the movement and power between any two shafts. Its peripheral speed can reach 300m / s, transmission power ca
- Advantages of cone sleeve driveWhat are the advantages of cone sleeve drive?The transmission of kinetic energy of pulley can alleviate the impact of load; the transmission of pulley is stable, low noise and low vibration; the structure of pulley transmission is simple and easy to adjust; the manufacturing and installation accurac
- Rack classification1. According to the tooth type, it can be divided into straight rack, oblique rack, etc.2. According to the type, it can be divided into conventional rack, straight / oblique rack, zero backlash rack and V-shaped guide rail rack, etc.3. According to the tooth surface treatment technology, it can be
- Gear shapingGear shapingUse gear shaper to process tooth surface of internal and external gear or rack according to generating method or forming method.Like gear hobbing, gear shaping is also processed by generating method. Gear shaper is like a gear with front and back angles to form cutting edge, so the princ
