The main factors that affect the gear transmission accuracy include: gear machining accuracy, gear accuracy grade, gear pair clearance requirements and gear pair contact point requirements.IHF gearGenerally, ...
2023-02-1428400The constant coincidence of the indexing circle and pitch circle of gear and rack mesh is also a prerequisite. The pressure angle of the indexing circle of the gear is 20 degrees. For the rack with a pressure angle of 20 degrees, their pitch circle coincides with the indexing circle. However, if the pressure angle of the indexing circle of the gear...
2023-02-1422000The gear drive needs two gears to operate. The two gear drivers are spur gears, and the drive gear receives force from the power output end. The driving gear transmits the power to the driven gear, and the gear transmission device relies on two or more meshing gears to transmit the power. The gear transmission ratio is accurate and suitable for hig...
2023-02-1323100Bevel gears are used for transmission between two intersecting shafts, and are most commonly used for transmission between vertical shafts. The straight bevel gear reducer is a bevel gear similar to the straight bevel gear, which is meshed and driven in a similar way. This kind of gear is very sensitive to assembly error, because the distance betwe...
2023-02-1318200With the extensive promotion of electromechanical integration technology, the machining accuracy of machine tools is getting higher and higher. Precise ball screw pair is widely used in numerical control equipment and other advanced equipment due to its superior performance. The ball screw is mainly developed for the purpose of driving device of ma...
2023-02-0413700There are three main methods to adjust the ball screw clearance:1. Shim clearance adjustment type: usually use screws to connect the flanges of the two nuts of the ball screw, and add shims between the flanges. Adjust the thickness of the gasket to make the nut produce axial displacement, so as to eliminate the gap and produce the pretension force....
2023-02-0417800For the drive belt pulley, the timing belt pulley is very important. Because of the addition and existence of the timing belt pulley, the drive belt can operate normally. The synchronous pulley is an integral part of the drive belt system. Most of the machinery driven by belt is small wheel with big wheel. This is because the rotating speed ...
2023-02-0329600(1) For high-speed, high-power and long-term working conditions, the transmission system with high bearing capacity, stable transmission and high transmission efficiency should be selected.(2) In the case of low speed, medium and small power and high transmission ratio, multiple schemes such as single-stage worm drive, multi-stage gear driv...
2023-02-0326200Due to different factors such as structural form, material and heat treatment, operating environment and conditions, the failure forms of gears are also different. Common gear failures include the following forms.1 Gear failure form and preventive measures1) Tooth surface fatigue (pitting, peeling)Cause and phenomenon:It is mainly due to th...
2023-02-0219800Based on the innovative concept, STOBER has developed a rack and pinion transmission system with compact structure, safe use and easy installation. The system is tailored for machine tool, automation and robot applications.STOBER can provide four different series of rack and pinion transmission systems, which are connected with STOBER planetary re...
2023-02-0233900The reducer is a key part of the industrial robot, accounting for about 32% to 37% of the production cost of the entire industrial robot. With the increase in the output of industrial robots, the demand for speed reducers will also increase rapidly. It usually needs to use four to six reducers, mainly RV reducers, while harmonic reducers are used l...
2023-02-0121700Common faults of hydraulic transmission systemIn the actual operation of the hydraulic transmission system of construction machinery, the common fault problems are as follows:1. The movement mechanism based on hydraulic power is unstable or does not move, which seriously affects the normal operation of construction machinery.2. The hydrauli...
2023-02-01192001. Deceleration or speed change deviceThe function of the deceleration or speed change device is to change the speed and torque of the prime mover to meet the needs of the working machine.2. Start-stop reversing deviceThe start-stop reversing device is used to control the start, stop and change the direction of movement of the working machi...
2023-01-3130310Role of mechanical transmission: The role of mechanical transmission is to transmit motion and force. The types of commonly used mechanical transmission systems include gear transmission, worm gear transmission, belt transmission, chain transmission, gear train, etc.Gear transmission: gear transmission is realized by shifting the driven gea...
