Reducing the load on the roller bit support

The support u bearing of the cone roller bit is an element that limits the resource of the drilling tool. The difficulty of studying the work of the supports bearing in the fact that the support is a multi-row integral bearing, where the durability of the bit as a whole depends on the performance of each bearing. The load sharing on the bearings depends on the placement of the teeth interacting with the face at a certain point in time. The number of load combinations that occur during the operation of the chisel is determined. Using the example drill cone bit type 632Y, seven combinations were determined. For each combination, the normal reactions occurring on each bearing and the bending moment in the sealing of the trunnion are determined. The Excel software module contains programs for calculating loads acting on bearings, contact endurance and operating time to failure of the bit support elements. Based on the analysis of the results, it is proposed to change the location of the teeth in order to ensure a more uniform loading of the support bearings and reduce the maximum reactions. At the same time, according to the Hertz formula, the contact stresses will decrease by up to 10%, and the bending moment in the sealing of the trunnion will also decrease.

Keywords: roller cone bit, load sharing calculation method, load sharing; bearing support, reliability of roller cone bits.
