Проверка зазора между упором рейки и гайкой
Fig. 5.3. Check of a gap between an emphasis of a lath and a nut: 1 – punch; X — the control size

Establish a lath in average situation which is defined by the size (87±0,25) mm (see fig. 5.6) from a gear wheel axis to a lath end face. By means of special adaptation load a lath with a force of P =500±20 N (51±2 kgfs) (fig. 5.3) at distance of 84 mm from a gear wheel axis towards a lath emphasis.
The most admissible movement of a lath of "X" measured through relative movement of a press punch 1 should not exceed 0,12 mm. After assembly the moment of rotation of a gear wheel in the field of the course of a lath has to be within 50–200 N · cm (5,1–20,4 kgfs · cm) at a speed of rotation of 30 min.-1.
