PBZF roller press reducer in the long-term use of played out the superior performance, has been the cement industry users. The following reducer on the use of roller press some of the issues to be addressed. Second, reducer installation and removal operations should be familiar with in the installation parameters before installation and check the speed reducer output shaft axis hole and installation of roller shaft with the size, confirmed only after the standard installation. This is important because the reducer output shaft bores and roller press roller axis with the size of the head may occur in some cases tolerance. Check if the installer directly without installation, with the gap is too small in the circumstances, may be fitted with roller reducer shaft can not be the first case, if the force loaded up, it could damage reducer. On the other hand, if the fit clearance is too large, may occur although the tightening plate installed by the rated torque, but the reducer output shaft bores and roller press roller shaft head with the surface can not generate the pressure required by the situation. In this case, with expected work, reducer hollow shaft and roller shaft head mating surface may 会 corresponding generation of rotation, it would seriously Sunshang roller shaft and the reducer output shaft, and may result in bonding with the surface, resulting in significant losses, should be determined to avoid this situation. Install reducer ago, and wiped the roller press and the reducer output shaft axis within the first hole, and for degreasing, should ensure reducer output shaft bore no oil. <br />
Reducer to the roller shaft in the installation process, should reducer output shaft bore and cylindrical roller shaft to look for is to avoid the hollow shaft of people in the installation process with roller shaft could not be loaded because skew. <br />
During the installation process, and strictly forbid the top end of the reducer input jack shaft, while the top end of the motor shaft AB, so as to avoid deformation or damage the input shaft of reducer input shaft support bearing. In addition, as motor bearing can not bear axial force, this can easily damage the motor bearings, causing motors not work. Reducer installed in place, with a torque wrench tighten gradually close tightening screw plate connection. Tightening is the order of successive equilateral triangle according to tighten the first screw to the rated torque of MA in the l / 4, and then successive increase of l / 4 rated torque tightening, the tightening process must maintain the two external pressure plate parallel to each other, it is important. Rated value and then repeat the tightening torque to ensure that each screw has reached the rated torque MA. <br />
Reducer input shaft and the half-coupling thermal loading, non-combat assembly. Half-coupling in heated oil inside, you can easily install the reducer input shaft of the. <br />
Motor and gear reducer through a scalable universal joint with a spline shaft connection. Although the universal joint to allow a certain degree of eccentricity, but in conditions permitting, should be to minimize the motor shaft and the eccentric shaft reducer, so that will help improve the transmission efficiency of the transmission system, to extend the life of universal joint shaft. With dial indicator check the motor shaft and reducer input shaft coaxial to see if it meet the assembly requirements, if met, can be installed by adjusting the motor base bolts to be adjusted. <br />
Need to open the disc in the tightening may run into this situation, tightening bolts were torn off and the connection plate, and two are inseparable connection pressure plate. In this case, you can create three wedge-site will be beating two tightening wedge pressure plate to separate from the cone. Reducer output shaft and hollow shaft roller press roller head in the long course of their work will be due the role of high-pressure plastic deformation and material part of the glue. For this reason, when the reducer shaft head need to remove from the roller press to time, often happens, tightening plate has completely let go, but the reducer can not take off, sometimes with dozens of tons Jack can not be aligned with the part of the disengagement. At this time, not use a large jack down, they are liable to damage reducer parts, on the other hand, even if hard to remove, and are likely to cause the first roller press and the reducer shaft serious scratch the surface of the shaft hole. In this case, you can pair with the outer surface area for uniform heating with a flame gun, etc. 加热 to a certain extent, and then try to jack Fen Li 2 with Jian. Practical applications indicate that this method is very effective. Third, the use of roller press reducer reducer with Oil circulation lubrication, good lubrication conditions is essential for the normal operation of reducer. <br />
Circulation of lubricating oil into the oil temperature should not exceed 45 ℃ or lower than 10 ℃, such as into the oily temperature higher than 45 ℃, should consider increasing or decreasing area of cooler cooling the temperature of cooling water, cooling water temperature should be lower than 30 ℃. Such as into the oily temperature lower than 10 ℃, heating oil should be considered. Reducer in lubricating oil is usually selected extreme pressure gear oil L-CKC320 (or VG320) when the temperature is below 0 ℃ was in solid form, can not play a role in lubrication, but also on the boot with great resistance. Currently reducer roller press mostly lubrication system for the tank to cycle box reducer lubrication, lubrication system is not set heater. This configuration is suitable for the warmer winter in China's southern region and the temperature is not low in northern areas, such as used in winter to 30 ~ 10 ℃ in a cold area, such as the Northeast region, Ningxia, Xinjiang, Inner Mongolia and other places, should be consider the lubrication system, a separate fuel tank configuration, set the heater in the tank. Thus, when the cold season need to start pre-heating oil can be had. No configuration on the heater and temperature are low and the situation down in the roller press, the reducer should be emptied of oil need to boot, to the restoration of the reducer through the heated oil can. To do up some trouble, but practical. <br />
<br />
Reducer's input shaft bearing with temperature measurement devices and control the computer display input shaft bearing temperature, this temperature is the work of user observations Reducer is an important parameter. According to experience, roller press reducer input shaft bearing temperature changes in the general range of 50 ~ 75 ℃. As the ambient temperature, cooling circulating water temperature, ventilation, and dust will affect the number of reducer oil temperature, so the normal input shaft bearing temperature range for each roller press is not the same. Specific to a particular station alarm roller press reducer how much the temperature should be set to debug the case may be according to the site. Reducer course of the work in the long term, if not abnormal, the temperature should always be in a relatively stable within the temperature range 变化 and should not be short Chu Xian Da Fudu the increase or decrease, otherwise, it may be the system where a single weak link failure, should be troubleshooting. <br />
When the reducer temperature above 70 ℃, even during the hot summer, also belong to the higher temperature. Reducer long-term high-temperature work, perishable oil, rubber seal aging easily. In this case, the cooling conditions in order to improve the speed reducer can be placed next to a fan in the reducer input shaft of the hair parts in order to improve the ventilation reducer. Practice shows that this lowering reducer input shaft bearing temperature is very effective, often can reduce the 3 ~ 5 ℃. 4, Troubles and reducer failure cause and solving method in Table 1.
