The position of several pairs of contact wires during the calculation of the dynamic stress of the planetary gear transmission root and the stiffness of the teeth of the corresponding position. According to the above analysis results, the meshing rigidity of the teeth is further obtained, and the d

The sawdust mill is used to crush the raw materials with smaller diameters. The diameter of the corn stalks and branches is less than 50 mm. The fineness of the materials after crushing can reach 3-5 mm. If you want to crush the wood with a diameter over 50 mm, you can customize it more. Large sawd

Under normal conditions, the tooth profile error curve generated during grinding is generally linear, that is, the pressure angle deviation occurs. In order to express the tooth shape pressure angle error, the tooth shape error is supplemented as follows: when the tooth root is convex, the tooth sh

First, the engine is difficult to start 1, cold start difficult, start after the vibration, vibration at low speed. It may be spark plug failure or ignition timing is too early. It is advisable to go to the nearest service station for overhaul. 2. It is d

The start of the garbage truck is basically the same as that of a normal vehicle. I believe we are all familiar with it. We must insert the key, place it in a spiral, and light up on fire. Is this still necessary for people to teach? Need to know, according

The author learned from the China National Machinery Industry Federation that since the “Twelfth Five-Year Plan”, the Chinese machinery industry has entered a medium-speed development channel of 12% to 15%. In this process, some elements of the Chinese machinery industry have also underg

Abstract : In order to adapt to the new dispatching system of the Northeast Power Grid, a real-time monitoring system for the junction control of the tie line was developed. The design principles and components of the system are introduced. The main algorithms for identifying and correcting bad data

As the last-ever domestic large-scale international auto show of the year, the Guangzhou Auto Show has always been an industry event that promises to come back and look forward to the coming year. This year's Guangzhou Auto Show is no exception. Each car company has high-profile announcements

In the next two years, 32 major LNG (liquefied natural gas) gas stations and two LNG ship filling terminals (Cangzhou and Yibin) will be deployed in major logistics parks in Sichuan Province, and 4000-6000 LNG heavy trucks will be promoted. This was revealed at the Green Logistics and New Energy P

Test voltage is usually the first step in solving a circuit problem. If there is no voltage or the voltage is too low or too high, the power supply must first be resolved before further inspection. The waveform of the AC voltage may be sinusoidal (sine wave) or non-sinusoidal (sawtooth, square wave,

Since the Production Preparation Team of the No. 1 Production Plant of Henan Oilfield has implemented the reformation of the crushing process of the sucker rod righting block, up to now, 60,075 of the various types of pumping rods have been overhauled, and there has been no accident of repairing a

At present, China has become the largest fastener producer in the world, but it has always faced claims arising from quality problems. There is a big case in which the quality of finished fasteners causes quality problems due to the quality of steel. In part, China's fastener steel still needs t
