The analytical, finite-element and multifactorial strain stressed state models of brake band and friction shoe are designed and tested under conditions of steady work brakes. The regularities of the stress distribution between the friction shoe and the brake band, between the friction shoe and brake drum, shoe wearing are researched for conditions of descent drilling tool into a well. Deformation of opened friction unit condition is investigated at the beginning of braking. Optimization of the brake band thickness and effort regulation mechanisms in the clearance friction unit are researched. The reasoning on improving the design are given. It is expected that the proposed improvements will increase the durability of the friction unit, the productivity of drilling and will provide economies of friction material.
