ZYS taper roller bearing crane maintenance operation 50 hours lubricated once

maintenance crane technology shift tooth surface work 10 once the debris should be removed and re- coated with grease.
 In order to ensure crane maintenance technical reliability of the bolt work to avoid bolt preload is insufficient, slewing the first 100 hours of work and 500 hours , respectively crane ZYS Precision Bearings maintenance should check pretension bolts . Then every 1000 hours of operation should be checked once pretension .
technology to connect maintenance crane slewing ring bolts and nuts are made of high-strength bolts and nuts ; double nuts and lock .
crane maintenance techniques tighten the nut should topcoat oil and nut threaded end of the bolt , and a torque wrench should be used uniformly in the circumferential direction ZYS taper roller bearings of symmetry repeatedly tightened. Crane Maintenance Technical finally tightened again when the crane maintenance techniques on each bolt tightening torque should be roughly uniform.
 crane maintenance technology in the slewing ring gear surface raceway parts are aligned cloth 4 cup oil , thereby adding grease to the Raceway . Under normal circumstances , slewing crane maintenance operation 50 hours lubricated once. Every crane maintenance techniques must add a little oil until the oil leaking from the seal so far .

To actively respond to national call for the elimination of ,ZYS Bearing Test Machine production capacity

Cixi : within two years of high energy transformers "laid off "
WASHINGTON ( Reporter correspondent Zhang Lu Li Li ) Recently, the City Power Supply Bureau powered by city staff came Yu Bo community , the community S7 -type high- energy transformer replacement for the new energy saving amorphous alloy distribution transformers , reduce power loss. So far, over 35 units within the city limits S7 ??-type transformers are replaced with high energy saving and environmental protection -type transformers.

To actively respond to national call for the elimination of ZYS Angular contact ball bearing  production capacity , accelerate the construction of new rural electrification , increase the energy saving new equipment applications . Recently, the City Power Supply Bureau launched a comprehensive high-energy transformer replacement work , a new round of rural power grids in the process of implementation of the elimination of old transformers work .

It is reported that the original transformer used for the S7 -type transformers, is the 1980s products , power loss, has been unable to further meet the increasing distribution network power quality and reliability , and vigorously promote the new ZYS Precision Bearings energy-efficient distribution transformers is imperative. In this high-energy transformer replacement work , S7 -type transformers will all be replaced with new energy-saving transformer - saving amorphous alloy distribution transformers . Energy amorphous alloy distribution transformer "posts ", the 10 kV line to reduce line loss rate . This is a loss of the transformer itself is only a year can reduce the energy loss of about 30 million kilowatt hours and reduce carbon emissions of approximately 265 tons .

in order to prevent accidents in the first place

For as long as possible in order to maintain the good condition of cylindrical roller bearings original performance , subject to maintenance, overhaul, in order to prevent accidents in the first place , to ensure the reliability of operation, improve productivity , economy . The best operating conditions and maintenance of appropriate machinery operating ZYS wind turbine bearing standards , regular basis. Including monitoring the operating condition , supplement or replace the lubricant regularly demolished checks. As a matter maintenance operation , a rotating bearing koyo sound , vibration, temperature , and so the state of the lubricant .
   Bearing cleaning:  overhaul cylindrical roller bearings , bearing koyo first recorded appearance to confirm the remaining amount of the lubricant , the lubricant after inspection sample , wash bearings. As a cleaning agent, the use of ordinary gasoline, kerosene.
   Cleaning bearings removed , cleaned of coarse and fine cleaning, were placed in the container, put ZYS Precision Bearings the first metal mesh bottom, so that no direct contact with the container bearing the dirt . Coarse cleaning , if the cylindrical roller bearings with rotating dirt will damage the bearing rolling surfaces , should be noted. In the crude oil washing , use a brush to remove grease, adhesive material, generally clean, into sperm washing .
Bearing cracking spalling is due to appear in the role of cycle koyo bearing loads , the contact surface is prone to fatigue damage caused , so in order to increase the service life of bearings , bearing steel must have a high contact fatigue strength.

Slewing ring raceway delamination how to repair broken teeth

Construction Machinery slewing material porosity due or mezzanine, swim raceway hardened layer hardness, depth manufacturing quality problems such as uneven or some external reasons, resulting in hardened raceway spalling or broken tooth ring gear, equipment will not work . For raceway delamination, we must first make the right judgments. Delamination occurs, generally the external hard to see. According to our experience, the following occurs, indicating a stripping layer raceway:
A host load is reversed, raceway have "slightly - slightly" abnormal sound, or an uneven azimuth rotation speed has slowed significantly and accompanied by a slight vibration.
Second, the rotary motor temperature is too high or too much current.
Third, the rotary motor and hydraulic coupling or coupling pushed up bad habits such as keyways. Delamination occurs, it must be repaired. Otherwise delamination area will be expanded to the entire slewing ZYS Precision Bearings scrap.
Repair method is: first slewing roller or ball inside out, so that separation of inner and outer rings; reuse raceway gasoline to clean; then use the grinder (wheel) carefully around the floor area has been generated crack hardened layer rubbed off, the bottom layer will peel polished; right place with the raceway requires welding and cutting torch preheat over medium carbon steel welding rod (electrode drying before use, and with the use of baking) , to make the solder layer just above the raceway surface 1-2mm; deeper if delamination or larger, should be layered segmented welding, do not make the base material caused by high temperature deformation; this avoids rapid cooling produces welding cracks after welding insulation measures should be taken immediately, so that he gradually cooled. After cooling grinder grind welding layer, making it slightly above the raceway surface, oil stone or emery cloth gradually metallographic grinding welding layer table, making it the normal surface raceway highly consistent with the corresponding original curvature model testing, until the qualifying date; clean with gasoline raceway and roller (ball) Apply grease, integrally assembled to complete.
