Ring structure is arranged in groove profile bearing seat 3 and lower 4 slot of groove profile bearing seat, and is carried rolling element 1 and can be held in upper groove profile
Carry free circulating rolling in seat 3 and lower 4 slot of groove profile bearing seat.
The carrying rolling element 1 includes roller 1-1, bushing 1-2, pin shaft 1-3 and split pin 1-4, and roller 1-1 weeks outside
Fillet 1-11 is arranged in side, and roller 1-1, bushing 1-2 and carrier bar 2 are connected by pin shaft 1-3, and are locked by split pin 1-4.
The upper groove profile bearing seat is divided into the segmental arc of horizontal segment and two sides, on the inside of the upper groove profile bearing seat 3 setting with
The arc surface 3-1 that the outer circumferential roller 1-1 fillet 1-11 is matched, 3 liang of side channel height of the upper groove profile bearing seat are in normal work
The lower edge of carrier bar 2 when making, guarantee is not interfered, and is fixed on bracket 5.
The mating vertical bogey in a kind of ground suitable for gauge-changeable bogie, it is characterised in that: under described
The shape of groove profile bearing seat 4 is in " C " word of opening upwards, is divided into the segmental arc of horizontal segment and two sides, the lower groove profile bearing seat 4
The arc surface 4-1 that inside setting is matched with the outer circumferential roller 1-1 fillet 1-11, lower two side channel of the groove profile bearing seat height
The lower edge of carrier bar 2 when working normally, guarantee is not interfered, and is fixed on bracket 5.
The utility model has the beneficial effects that
The mating vertical bogey in a kind of ground suitable for gauge-changeable bogie described in the utility model is suitable for axle box
It is brought to have the beneficial effect that in the gauge-changeable bogie ground corollary apparatus of carrying:
The carrying rolling element radial dimension of the utility model is smaller, and bearing capacity is strong, so as to reduce axle box or axis
The size that boots are carried under case, reduces the unsprung mass of gauge-changeable bogie, improves bogie riding quality；
The vertical bogey lateral dimension of the utility model is small, leaves space for arrangement other structures in transverse direction, easily
It is realized in the arrangement and function integrally equipped；
Vertical bearing capacity big requirement when the vertical bogey of the utility model is not only able to satisfy gauge changing, but also structure
Simply, good rigidity, manufacturing cost is low and convenient for safeguarding, similarly has reference value to other industry load bearing equipments；
