The worm drive is a transmission that transmits motion and power between two axes that are interlaced in space. The angle between the two axes can be any value, and is usually 90°. The worm drive is used to transfer motion and power between the staggered axes. There is only one spiral on the worm …
Worm gear mechanisms are commonly used to transmit motion and power between two staggered shafts. The worm gear and the worm are equivalent to the gear and the rack in the middle plane, and the worm is similar in shape to the screw. Basic parameters Modulus Pressure angle Worm diameter coefficient Lead angle Number of …
Friction drive is a new friction drive ring composed of friction block and connecting piece. The friction blocks are locked together and integrated, which is safe and reliable to use. The scope of use The material of the friction block is synthetic fiber, which is composed of light leather, chrome tanned leather and plant fiber, …
Synchronous belt drive means that the belt and the pulley are meshed to transmit motion and power. The timing belt transmission is composed of a ring belt having an equally spaced tooth shape on the inner circumferential surface and a wheel having a corresponding anastomosis. It combines the advantages of belt drive, chain drive and …
The belt drive is a mechanical transmission that utilizes a flexible belt that is tensioned on a pulley for motion or power transmission. According to the different transmission principle, there is a friction type belt transmission which is driven by friction between the belt and the pulley, and a timing belt transmission which is driven …
The chain drive is a transmission method in which the movement and power of a drive sprocket having a special tooth shape is transmitted to a driven sprocket having a special tooth shape through a chain. The main advantages of chain drive are: Compared with the belt drive, no the inelastic sliding and slipping phenomenon, …
A transmission mechanism is a member or mechanism that transfers power from one part of the machine to another, and the movement or operation of the machine or machine components. Function (1) Change the output torque of the power machine to meet the requirements of the working machine; (2) Transforming the motion of the output …
(1) Cylindrical gear transmission For transmission between parallel shafts, the general transmission ratio can be up to 8 in a single stage, the maximum is 20; the two stages can be up to 45, the maximum is 60; the third level can be up to 200, and the maximum is 300. The transmission power can …
Rolling bearing is a kind of precise mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. Rolling bearings generally consist of four parts: inner ring, outer ring, rolling element and cage. The inner ring functions to cooperate with the shaft and …
Angular contact ball bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase. Accuracy level Angular contact ball …
Basic parameters Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. Deep groove ball bearing types are available in single row and double row. The deep groove ball …
A needle bearing is a roller bearing with cylindrical roller that is thin and long relative to its diameter. This type of roller is called needle roller. Despite its small cross section, the bearing still has a high load carrying capacity. Features Needle roller bearings are equipped with thin and long rollers (roller diameter D …
Thrust ball bearings are designed to withstand thrust loads at high speeds and consist of a washer-like ferrule with ball rolling groove grooves. Since the ferrule is a cushion shape, the thrust ball bearing is divided into two types: flat base cushion type and self-aligning spherical seat cushion type. In addition, this bearing can withstand …
Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can …
The rolling element is radial rolling bearing of cylindrical roller. The internal structure of the cylindrical roller bearing is arranged in parallel by rollers, and spacers or spacers are arranged between the rollers to prevent the rollers from tilting or friction between the rollers, thereby effectively preventing an increase in the rotational torque. Overview Cylindrical …
Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has lower friction factor, higher speed and self-aligning performance. Product Features The roller of the 29000 type bearing is an …
The transmission system is generally composed of clutch, transmission, universal transmission, final drive, differential, and half shaft. Its basic function is to transmit the power from the engine to the driving wheels of the car, generating driving force, so that the car can drive at a certain speed. Mainly can be divided into two categories: …
Introduction An insert bearing with housing is a bearing unit that combines rolling bearing with bearing housing. Most of the outer spherical bearings have spherical outer diameter that is mounted with inlet bearing housing with spherical inner bore. The structure is diverse, versatile and interchangeable. At the same time, these bearings are also designed with …
The spherical roller bearing is a bearing in which the drum-shaped roller is assembled between an inner ring having two raceways and an outer ring having a spherical race. Spherical roller bearings have two rows of rollers that are primarily subjected to radial loads and can also withstand axial loads in either direction. High radial …
The self-aligning ball bearing has two types which includes cylindrical hole type and tapered hole type. The material of the cage is steel plate, synthetic resin, etc. It is characterized by a spherical shape of the outer ring raceway and automatic self-aligning. It can compensate for errors caused by different degrees of concentric and shaft …
