Description

Wheel duplex bearing support construction

Technical field

The utility model relates to a kind of wheel duplex bearing support constructions, belong to the support construction technical field of axis.

Background technique

It is linked together between road sweeper wheel carrier and hub for vehicle wheel by terminal pad, centre passes through axletree, terminal pad One end is fixedly connected with wheel hub, and bearing is laid on the terminal pad other end, and axletree and wheel carrier are fixedly connected one It rises.Wherein, the wheel hub of wheel is directly sleeved on axletree, pushes resistance very big, axis very serious to the abrasion of wheel hub and axis The receiving pressure held is big, and wheel walking is unstable, causes the service life of all parts to shorten, increases maintenance cost and maintenance Number.

Utility model content

The purpose of this utility model is to solve that deficiency exists in the prior art, and road sweeper walking resistance can be made by providing one kind The wheel duplex bearing support construction that power is smaller, walking is more stable, less abrasion, extends service life, saved maintenance at This.

The utility model is achieved through the following technical solutions:

I.e. a kind of wheel duplex bearing support construction, including wheel and wheel carrier, wheel include tire and wheel hub, wheel hub inner end On be fixedly installed with terminal pad, terminal pad inner end is equipped with inner rotary table gear, and wheel carrier is located at inner rotary table gear inner end, across vehicle Wheel carrier, terminal pad and wheel hub are equipped with axletree, are fixedly connected between axletree and wheel carrier, cover between axletree and terminal pad There is bearing two, set is equipped with bearing block there are two nylon sleeve between axletree and wheel hub in the hole of wheel hub outer end, in bearing block Bearing one is laid, blind screw hole is offered on the outer end face of axletree, bolt is installed in the blind screw hole of axletree And gasket, gasket compress the inner ring of bearing one, and bearing block capping is connected on bearing block outer end face.

The utility model makes road sweeper walking resistance smaller, walks more stable, and the less abrasion of all parts extends Service life, has saved maintenance cost.

Further preferably, the inner ring of bearing one is compressed close to the nylon sleeve of outer end.

Further preferably, ladder hole is offered in bearing block, the biggish hole of internal diameter is inner, bearing one be mounted on internal diameter compared with In big inner hole, bearing block capping inner end is stuck in the lesser inner hole of internal diameter.

Compared with prior art, beneficial effect possessed by the utility model is:

Specific embodiment

Below against attached drawing, specific embodiment of the present utility model is described in further detail.

A kind of wheel duplex bearing support construction as shown in Figure 1 and Figure 2, including wheel 7 and wheel carrier 8, wheel 7 include wheel Tire and wheel hub, are fixedly installed with terminal pad 12 on wheel hub inner end, and 12 inner end of terminal pad is equipped with inner rotary table gear 9, and wheel carrier 8 In 9 inner end of inner rotary table gear, passes through wheel carrier 8, terminal pad 12 and wheel hub and be equipped with axletree 11, axletree 11 and wheel carrier 8 Between be fixedly connected, bearing 2 10 is cased between axletree 11 and terminal pad 12, set is there are two Buddhist nun between axletree 11 and wheel hub Imperial axle sleeve 6 is equipped with bearing block 5 in the hole of wheel hub outer end, ladder hole is offered in bearing block 5, and the biggish hole of internal diameter is inner, Lay bearing block 5 in the biggish inner hole of internal diameter, offer blind screw hole on the outer end face of axletree 11, axletree 11 it is interior Bolt 2 and gasket 3 are installed, gasket 3 compresses the inner ring lateral surface of bearing 1, the nylon sleeve 6 close to outer end in tapped blind hole The inner ring medial surface of bearing 1 is compressed, bearing block capping 1 is connected in the lesser inner hole of 5 internal diameter of bearing block.

Working principle:

The utility model, which is mainly reflected in, is provided with 2 10 two bearings of bearing 1 and bearing, in the prior art only Buddhist nun 2 10 two structures of imperial axle sleeve 6 and bearing, and increase bolt 2, gasket 3, bearing 1 and bearing block 5, wheel carrier 8 and vehicle Be between wheel shaft 11 it is fixed, when pushing road sweeper, wheel 7 is operated, while with dynamic bearing 1, nylon sleeve 6, inner rotary table Gear 9 and bearing 2 10 operate therewith, and frictional force will be generated between axletree 11, then generate resistance, this is practical new The increased bearing of type can share load capacity, while mantle friction Variable roll friction, substantially reducing frictional force, then reducing Promotion resistance, pushes i.e. light and laborsaving, while bearing and nylon sleeve 6 are hardly damaged, extend service life, subtract Few repair and replacement number, has then saved maintenance cost.

The orientation or positional relationship of the instructions such as term "inner", "outside", "upper", "lower" is in the description of the present invention, It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the utility model rather than requires the utility model must It must be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
