FIELD: machine-building. ^ SUBSTANCE: invention related to running block wheel. The running block wheel contains a case (2), with at least one junction surface (3A), receiving payload and slide bearings and/or rolling bearings (5) landing surfaces (4) of the running wheel (6). For the wheel (6) dismount form the case (2) take bearings out (5), and the wheel itself - through the side (8) in lateral direction. Landing surfaces are channel shaped (9), made directly in the case walls not using landing rings. To make mounting/dismounting processes easier and to increase running wheel installation accuracy, landing surfaces (4) made in a way that they form segment bigger than half-ring around the bearing (5), leaving the side section (8) open, forming that way more narrow passing field. ^ EFFECT: simplification of running wheel mounting/dismounting or change. ^ 8 cl, 1 dwg |
