Because load is applied on this equipment during operation, the installation quality of base frame foundation is demanding. The base frame and foundation shall have good contact to ensure smooth running of equipment. The installation height and permissible position error are as follows:

Main shaft installation: Fit front bearing onto main shaft, and place the main shaft in spindle box by use of lifting bolt. Then install rear bearing into the spindle box, and use lock nut to tighten taper sleeve. Finally put thrust bearing into end cap, and use bolt to fasten the end cap on the spindle box.

Support installation: After assembling, long shaft (YJ60.02.05), short shaft (YJ60.02.15) and their bearings (60.02.04) and spindle box (YJ60.01.01) shall be hoisted and installed on the base. After assignment, use taper pins for positioning and then tighten bolts.

Disc installation: Connect main gear (307.03 spare 01.13) and middle disc (307.03 spare 01.15) together by bolt. Check and confirm that nothing is loose. Use lifting hook to hoist this component horizontally, and at this time the main shaft shall be placed perpendicular to the ground. Use fixing plate to fasten the spindle box on base frame (as shown in the figure below), and fit disc hub onto the main shaft, and then connect the disc and main shaft by bolt and gland. Install side bracket and side disc, and use pins for positioning and tighten bolts after geometric tolerance has met the requirement. Tighten the bolts again after load running for 200 hours.

Hoist the disc by use of lifting hook and steel wire rope, and then remove the fixing plate and get prepared for installation of inclination adjusting device. Check if connected steel plate has enough strength and make adjustment. And check if the hinge mount connected with adjusting device is loose, if weld joint is tight and even and if the location of upper and lower hinge mount meets requirement. Install adjusting device only after all these are qualified.

Install support I (YJ60.02.02) at both sides of long shaft and short shaft and fasten the shafts to the support by use of pin. Tighten hand wheel (YJ60.02.07)and then install support II (YJ60.02.06). The geometric tolerance shall meet requirements in the figure.

Complete the assembling of scraper and ensure flexible rotation of shaft. Then install the scraper entirely on the beam and adjust the position of tool bit, which shall be 30mm away from disc surface. Installation location tolerance shall meet the requirements in the figure.

After installing the motor and reducer, check the degree of tension for V-belt and make sure that it is neither too tight nor too loose.

Including gear cover, inspecting stand, lubricating pipeline and etc.. Careful and comprehensive inspection shall be carried out on the equipment by reference to the drawing and this manual, including the tightness of each bolt, if mounting position of each component is correct, and if there exists interference phenomenon during hand turning. And careful check shall be made on lubricating device and its pipeline system to ensure unblocked oil circuit at various lubricating points.
