On seat board, brake(-holder) block is connected on pressing plate, the brake(-holder) block is mounted on by screw on pressing plate, in the effect of platen pressure
Under, frictional force is generated with wheel, brake force is provided when wheel needs positioning；The spring is mounted in the groove of seat board, set
On bolt, when nut unclamps, pressing plate can be jacked up；Seat board is mounted on by screw on wheel mount.
Preferably, the bearing is mounted in the groove of wheel, and bearing outer ring is fitted close with inside wheel groove, limitation
Bearing outer ring rotates, and bearing inner race is fitted close limitation bearing inner race rotation with axletree；The sleeve is axial in limitation bearing
Bearing inner race is withstood while mobile, ensures wheel smooth movements.
Preferably, the dust-proof cushion is mounted in the groove of wheel, prevents dust and foreign matter from entering in bearing, ensures wheel group
Operational security.
Preferably, the baffle ring is mounted in wheel, limits bearing axial float.
Preferably, the wheel has 1 with rail contact face:10 taper can make wheel group do centripetal movement.
More traditional rail wheel, the utility model rail wheel group have the characteristics that：
(1) modularity designs, and is easily installed and replaces.
(2) wheel group is symmetric design, and the interchangeability of wheel group is good.
(3) wheel group increases braking function, facilitates the positioning of wheel group.
(4) braking function has spring to provide screen resilience, easy to operation
Description of the drawings
Fig. 1 is the front view of equipment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A direction views of Fig. 1.
Fig. 4 is the overall schematic after assembling.
Specific implementation mode
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, wheel mount 1 is the basic part of sleeve mechanism, and other parts are all mounted on it
On, it is the connecting hole of entire wheel unit and miscellaneous equipment to have the hole of 4x Φ 18 on wheel mount.
Sleeve 2 withstands bearing inner race while limiting bearing axial movement, ensures wheel smooth movements.
Axletree 3 is the primary load bearing component of a whole set of wheel group, and cooperation wheel realizes rotating function.
Axle end baffle plate 4 is bolted on wheel mount, can be with the axial float of limiting wheel axis.
5 wheel of wheel is the core part of entire wheel group, and there is groove in inside, for installing bearing 6, baffle ring 14 and dust-proof cushion
7；There is wheel rim in outside, prevents from derailing；Wheel has 1 with rail contact face 15:10 taper can make wheel group do centripetal movement.
Bearing 6 is mounted in the groove of wheel 5, and outer ring is tight fit with wheel groove, limits outer ring rotating, inner ring and vehicle
3 tight fit of wheel shaft limits inner ring rotation.
Dust-proof cushion 7 is mounted in the groove of wheel 5, can prevent dust and foreign matter from entering in bearing 6, ensures the operating of wheel group
Safety.
Pressing plate 8 is mounted on by bolt 10 and nut 11 on seat board 13, is connected with brake(-holder) block 9 thereon.
Brake(-holder) block 9 is mounted on by screw on pressing plate 8, and under the action of platen pressure, frictional force is generated with wheel 5,
Wheel needs to provide brake force when positioning.
Spring 12 is mounted in the groove of seat board 13, is sleeved on bolt 10, when nut 11 unclamps, can be pushed up pressing plate 8
It rises.
Seat board 13 is mounted on by screw on wheel mount 1.
Baffle ring 14 is mounted in wheel 5, limits 6 axial float of bearing.
In actual use, the utility model rail wheel group uses in groups, and 18 holes 4x Φ in wheel group are set by bolt and use
Standby connection.Nut 11 is thoroughly unclamped when operation, brake(-holder) block 9 and pressing plate 8 are bounced, protected between brake(-holder) block 9 and wheel 5 by spring 12
Certain gap is held, wheel group can be rotated smoothly.When braking, after equipment comes to a complete stop, tightens nut 11 and come clamping platen 8 and system
Movable plate 9, the frictional force generated between brake(-holder) block 9 and wheel 5 are convertible into the brake force using equipment.
Above example is only that preferred embodiments of the present invention are described, not to the model of the utility model
It encloses and is defined, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to the utility model
