1.Introduction：
Directional connector has two forms, directional bending joints and directional direct head. It is one of main tools in the making of power drilling tools. Power drilling tools give the drill continuous lateral force to make the drills continuously incise borehole wall under the effect of directional connector, and finally can be completed the curve of the well bore track.

- Q: Feroform what bearing material, metal or nylon, or anything else?
- It's made of toughened and wear-resistant nylon, which is more high-grade. As bearings, there are generally PA66+30GF/CF, PA66+PTFE+GF/CF, PA66+, molybdenum disulfide, of which the most cost-effective is PA66+ molybdenum disulfide. Our company has production, and if necessary, you can contact me.
- Q: Machine specific, please describe the specific points
- Many types of bearings. According to the direction of the load it can withstand can be divided into: the radial bearing, also known as radial bearings, bearing radial load. The thrust bearing, and thrust bearing, bear the axial load. The radial thrust bearing, also called centripetal thrust bearing under radial load and axial load at the same time according to the nature of work. The friction bearing can be divided into different sliding friction bearings (the sliding bearing) and rolling friction bearings (the rolling bearing) two categories.Angular contact bearings: ball and raceway nominal contact angle greater than 0 degrees, the rolling bearing and less than 90 degrees. At the same time can bear radial load and axial load. Can work at a higher speed. The larger the contact angle, the axial bearing capacity is higher. The high precision and high speed bearings usually take 15 degrees contact angle in the axial direction. Under the action of force, will increase the contact angle. The axial load of ball bearings can only bear a direction, in radial load, will cause additional axial force. The axial displacement and can limit shaft or shell in one direction. If the duplex mounting, so that a pair of bearing outer ring relatively, i.e. the wide end of the wide end, the narrow end face with narrow end. So to avoid the additional axial force, but also in the two direction of the shaft or shell limit in the axial clearance range.
- Q: where can I buy other GPS drilling accessories? I have some GPS rigs.
- With so many rigs, you can buy it directly from Wuhan Jintai Geological Engineering Machinery Co., ltd.... They have all rig accessories, very, very complete. You can call them 400
- Q: The car separation bearing is broken, isn't it? What's the cause of the other broken bearings?
- Judging the quality of the separation of bearings: step down the clutch pedal to half linkage position, and then make a noise, you can judge the separation of bearing damage
- Q: What else does the sleeve do in it? What other auxiliary small parts do they need besides the sleeve?
- Standard installation method: the bearing heating, the use of thermal expansion and contraction principle, installation time and effort, delaying bearing life, knocking bearings will destroy the bearing accuracy, coordination clearanceTeacher craftsman installation method: no fixed tools, sleeve, hammer, basic equipmentSpecial tips on what tools are for
- Q: In engineering practice, for needle roller bearings, usually axial positioning is the same as other bearings?
- Needle bearing features are axial can not bear the load, so the operation of the axial direction of the bearing no force, radial installation slightly tight can be, the axial need not limit
- Q: Characteristics of cross roller bearings
- Cross roller bearings, with the inner and outer ring divided into, roller and interval retainer, and cross roller collar fixed together, separated from each other to prevent the installation of cross roller collar simple operation. Because roller cross arrangement, so only 1 sets of cross roller collar can withstand various direction load, compared with the traditional model, increase the rigidity of 3~4 times. At the same time, because the cross roller bearing inner ring or outer ring is a two division structure, the bearing clearance can be adjusted, even if the preload is applied, high precision rotary movement can be achieved.1, with excellent rotation accuracyThe internal structure of cross roller bearings is made of 90 degrees vertical cross arrangement of rollers,The roller is provided with an interval retainer or an isolating block, which prevents the tilting of the roller and the grinding between the rollers. In addition, the phenomenon of side contact or locking of the roller can not occur; at the same time, because the inner and outer ring is a segmented structure, the clearance can be adjusted, and even high-precision rotation can be obtained even if the preload is applied.2. Simplify the operation and installationThe outer ring or inner ring divided into 2 parts is fixed together after the roller and retainer are mounted, so the installation is very simple.3, bear larger axial and radial loadBecause the rollers are arranged perpendicularly to each other on the rolling surface of the V groove on a 90 degree angle.
- Q: why the inner ring of a knock on the broken, and other small manufacturers desperately not broken, is the material problems or other reasons? The hardness is about the same. LYC62 another 63. How can this be explained? Seek expert advice!
- You may have this bearingImitationThe hardness is not too high,High imitation is the quality of the bad ah!
- Q: Bearing, in addition to interference, excessive, gap three kinds of co-ordination, there are no other coordination?
- Not only bearings, but only three of these combinations
- Q: I want to use laser displacement sensor to measure the displacement of the slider. I hope the master will recommend a sensor.
- Are you using them on machine tools? If so, I know that the jack sensor has something for you. You can look them up at their website first.
