Quartz Stone Powder Small Grinding Machine Drive Installation Steps

The Quartz Stone Powder Small Grinding Machine mainly has two transmission forms, namely center drive and edge drive. The two transmission forms have their own advantages and disadvantages. The central transmission adopts a high-speed planetary reducer, which is safe and reliable. The service life can reach 10 years and the maintenance cost is low, but the one-time investment is large.

Edge drive costs are lower, but pinions need to be replaced every 2 to 5 years. The edge drive is mostly used in coal mills and Quartz Stone Powder Small Grinding Machines with low power. The large and small gears are the key in the edge transmission. The reliable operation is directly related to the stable production of the Quartz Stone Powder Small Grinding Machine. In order to ensure its reliable operation, in addition to strengthening daily maintenance and regular maintenance, the installation and correction of the large and small gears is also crucial. important.

Edge Drive Installation Alignment

The installation and alignment process of the edge transmission device is as follows: cleaning of the ring gear and the Quartz Stone Powder Small Grinding Machine flange → seating of the ring gear → rough correction of the large ring gear → small gear positioning and rough alignment → installation of the motor reducer → once Grouting → fine tuning of the ring gear → fine gear of the pinion → motor gear reducer. The correcting work of the large and small gears is particularly important. This paper briefly describes the process of aligning the large and small gears.

Correction Of The Big Gear

In order to reduce the workload when installing gears on site, when the gears are finished, the hobs with similar wear conditions should be used to make the meshing contours of the large and small gears as close as possible, thus increasing the contact area. Before the gear is installed, the conditional site can use the tooth thickness vernier caliper to check the ring gear tooth thickness. Or the steel plate can be used to make the tooth profile, and the tooth shape can be retested. If necessary, it needs to be repaired on site.

1, Ring Gear Face Detection

After the ring gear is assembled to the cylinder according to the installation mark, connect the bolt to the tight joint surface to detect whether there is a step on the side of the gear (require the step to be as small as possible, otherwise it will affect the end jump of the ring gear). With a 0.04mm feeler gauge, the insertion depth is required to be 50mm, and the cumulative length of the gap is not more than 1/4 of the tooth width.

2, Ring Gear Runout

When measuring the diameter of the jump, it is necessary to use the winch for disc grinding. Before the disc grinding, the Quartz Stone Powder Small Grinding Machine slide or the hollow shaft oil station must be opened, and the float of the Quartz Stone Powder Small Grinding Machine should be checked with a dial gauge. The float up to 0.15 mm can be used for disc grinding. Most of the on-site measurements of the hop time dial gauge are installed in the position in Figure 1 or Figure 2, each of which has advantages and disadvantages.

In the position in Figure 1, the diameter jump of the tooth top can be directly measured, but it is necessary for a worker to hold the dial indicator under the ring gear. When the tooth to be measured is turned over, the dial indicator is released, which is complicated and easy to cause workers Injured.



The position in Figure 2 is simple to operate, but it is not the true diameter jump of the gear. Therefore, we recommend making a measurement tool (Figure 3) that is mounted on the meter head so that it is easier to measure the runoff (Figure 4). The ring gear needs to measure 8 points a week, as shown in Figure 5. The diameter jump requirement is: ≤ 0.25D (unit: mm), and D is the gear index circle diameter (unit: m).

3, Ring Gear End Beating

When measuring the end jump, it is still necessary to use the hoist to perform the disc grinding. Before the disc grinding, the Quartz Stone Powder Small Grinding Machine slide or the hollow shaft oil station must be opened, and the floater should be checked by the dial gauge. The float up to 0.15mm can be used for the disc grinding. If the field personnel are sufficient, the end jump and the run jump can be measured simultaneously.


The end jump must be detected by the double table method to eliminate the error caused by the axial movement of the Quartz Stone Powder Small Grinding Machine. When the two dial gauges are mounted on the same side of the ring gear, as shown in the left position in Figure 6, the end jump is calculated according to the fourth row in Table 1; when the two dial gauges are mounted on both sides of the ring gear, as shown in Figure 6. In the middle right position, the end jump is calculated according to the fifth line in Table 1. The two dial gauges must be installed at 180° and the ring gear must be measured at 8 points a week, as shown in Figure 5. The end jump requirement is: ≤ 0.25D (unit: mm), and D is the gear index circle diameter (unit: m).

Four Steps Ensuring Safety And Efficiency Of Machine Preparation And Shipment

  • 1. Checking order. With the sales contract, the order tracking clerk checks the models and quantities of machine and spare parts for machine preparation.
  • 2.Quality test before delivery. Upon completion of the manufacturing of equipment, the quality inspector strictly checks quality of every machine with the checklist.
  • 3. Check items when packing. Before packaging and shipment, the order tracking clerk checks the packaged items again with the packing list to avoid loss of items.
  • 4. Packaging and transport. Professional packaging and modular solution of transportation guarantee the safe and smooth delivery.
