ABSTRACT

Figure 28.3 shows the construction of the teeth with radial working surface (a) and inclined at angle β to the radial plane (b). The hinge of the pawl is placed so as to obtain the required angle α between the line of pressure of the pawl in the beginning of engagement (line 1) and the perpendicular raised to the tooth working surface at the tooth tip (line 2). Length L is chosen from other considerations, such as available place, angle of rotation of the pawl, etc.
