Background technique

In recent years, my country's bearing industry is in a period of rapid development, and the production and sales are increasing day by day. Considering the long-term development, users have put forward higher requirements for product quality. This requires our bearings to not only have exquisite appearance quality, but also need to have excellence The internal process, especially the large and heavy slewing bearing, the ring gear is difficult to process, and the measurement is even more difficult. Therefore, we have conducted research on how to quickly and accurately measure the runout measuring device of the ring gear of the turntable bearing.

At present, complete sets of bearings are mostly used to measure the runout of ring gears and gears of large turntable bearings. The measurement method is simple, but the error is large. Use a magnetic gauge and a suitable modulus tooth bar to measure. When measuring, two people are required to rotate the bearing, and one person is to measure and count. Turn the turntable bearing ring gear teeth again and again, and then measure again and again, which affects the speed of inspection. , due to the existence of radial clearance, it affects the measurement accuracy and causes a lot of waste of manpower and material resources.

Utility model content

The technical problem to be solved by the utility model is to provide a measuring ruler that can improve the speed and quality of processing or inspection, save material resources and labor costs, has good safety performance, high production efficiency, and is easy to carry for measuring the beating of the ring gear of the turntable bearing .

The technical solutions adopted are:

The utility model relates to a measuring ruler for measuring the runout of the ring gear of the turntable bearing, which includes a base plate, a measuring component, and a spherical fulcrum component. The base plate is placed horizontally, a through hole is opened on the left end of the base plate, and a plurality of gauge stem jacks are opened on the right end of the base plate, and threaded holes are set on the side corresponding to the gauge stem jacks. The measuring assembly includes a dial indicator and a measuring rod. The measuring rod is arranged vertically. The upper end of the measuring rod is inserted into a selected rod socket on the base plate and fixed with a locking screw of the measuring rod. The dial indicator is installed at the lower end of the measuring rod, so that the dial indicator probe contacts the surface of the radially measuring raceway of the ring gear of the turntable bearing to form a measuring assembly. The spherical fulcrum assembly includes a column locking screw, a column sleeve, a hollow ball fulcrum, and a locking screw cap. The column locking screw goes through the through hole at the left end of the base plate, and the column locking screw located under the base plate is fitted with the column sleeve and the hollow ball fulcrum in turn, and finally the hollow ball fulcrum and the column sleeve are locked on the base plate with the locking screw cap. The hollow ball fulcrum is located between two adjacent teeth of the slewing bearing ring gear, and is tangent to the inner tooth surfaces of the two adjacent teeth to form a spherical fulcrum assembly.

The utility model has the advantages of being convenient and accurate, simple to manufacture, convenient for the measurement of the beating of ring gears of various specifications of turntable bearings, improving the working efficiency of workers and reducing the labor intensity of workers.

Detailed ways

A measuring ruler for measuring runout of a ring gear of a turntable bearing includes a base plate 1 , a measuring assembly 11 , and a spherical fulcrum assembly 12 . The base plate 1 is placed horizontally, and the left end of the base plate 1 is provided with a through hole, and the right end of the base plate 1 is provided with four gauge stem jacks 4 , and threaded holes are provided on the side corresponding to the gauge stem jacks 4 . The measuring assembly 11 includes a dial indicator 3 and a measuring rod 2, the measuring rod 2 is vertically arranged, and the upper end of the measuring rod 2 is inserted into a selected rod jack 4 on the substrate 1, and the measuring rod 2 can be Move up and down in the table rod socket 4 on the base plate 1 to find a suitable height, and fix it with the measuring table rod locking screw 5 . The dial indicator 3 is installed at the lower end of the measuring rod 2, and can move left and right, find a suitable position and lock it, so that the measuring head of the dial indicator 3 contacts the surface of the radial measurement raceway of the turntable bearing ring gear 10 to form a measuring assembly. The spherical fulcrum assembly 12 includes a column locking screw 6 , a column sleeve 7 , a hollow ball fulcrum 8 , and a locking screw cap 9 . The upright sleeve 7 is a plurality of upright sleeves with the same inner diameter and outer diameter but unequal lengths, so as to be used for adjusting the height of a suitable hollow ball fulcrum 8 .
