Description

A kind of milling locomotive wheel

Technical field

The utility model relates to engineering machinery wheel fields, particularly relate to a kind of milling locomotive wheel.

Background technique

Currently, pavement milling machine is one of main machine of asphalt pavement conserving construction machinery, asphalt concrete pavement is supported One of the capital equipment of construction is protected, the excavation for being mainly used for the asphalt concrete pavements such as highway, town road, airport, goods yard turns over Newly, it can be used for removing the defects of packet, oily wave, reticulate pattern, track are gathered around in road surface, may further be used to excavated pavement pit slot and groove, with And the milling of the plucking and surface layer faulting of slab ends of cement pavement is flat.

The wheel of existing milling machine uses crawler type vehicle wheel, and the characteristics of crawler type vehicle wheel is that driving force is big, cross-country ability And stability is good, climbing capacity is big and turning radius is small.Damaged tyres road surface is serious when crawler type vehicle wheel is run, and is not suitable for city City's construction, crawler type vehicle wheel is heavy, not flexible, and transition is inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of milling locomotive wheels, stupid for solving milling locomotive wheel in the prior art Heavy, not flexible and inconvenient transition problem.

To achieve the above object, the utility model the following technical schemes are provided:

A kind of milling locomotive wheel, the press-fitting circle including having solid tyre, the inner ring connection disc circle of the press-fitting circle Cylinder, the middle position of the cylinder inner ring connect the disc outer ring of the disc circle.

Wherein, the 4-6 notch of multiple circumference uniform distributions is equipped on the disc at the cylinder.

Wherein, the center of the disc is equipped with through-hole.

Wherein, one end in the cylinder both ends has 10 ° -15 ° of chamfering.

Wherein, the shape of the notch is circular shape.

Wherein, the mounting hole of 6-10 circumference uniform distribution is equipped on the disc close to the through hole.

Wherein, it is equipped with screw hole close to the through hole on the disc, the center of the screw hole is into the disc The distance of the heart is equal to the center of the mounting hole to the distance at the disc center.

The above-mentioned technical proposal of the utility model has the beneficial effect that:

In above scheme, the milling machine car wheel structure of the utility model is simple, and light-weight, mobility is good, and transition is convenient, fits For middle-size and small-size road surface operation.

Specific embodiment

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing And specific embodiment is described in detail.

The utility model problem heavy, not flexible and inconvenient transition for existing milling locomotive wheel, provides one kind Milling locomotive wheel.

As shown in Figs. 1-2, the utility model embodiment provides a kind of milling locomotive wheel, including having solid tyre Press-fitting circle 1, it is described press-fitting circle 1 inner ring connection disc circle 2 cylinder 21,21 inner ring of cylinder middle position connection described in 22 outer ring of disc of disc circle 2.

Wherein, the 4-6 notch 3 of multiple circumference uniform distributions is equipped on the disc 22 at the cylinder 21.The notch 3 Play the role of heat dissipation, mitigates wheel weight in the case where meeting carrying.

Wherein, the center of the disc 22 is equipped with through-hole 4.

Wherein, one end in 21 both ends of cylinder has 10 ° -15 ° of chamfering.Convenient for the cylinder 21 and the press-fitting 1 press-fitting of circle, so that being easily pressed into when press-fitting.

Wherein, the shape of the notch 3 is circular shape, avoids the occurrence of problem of stress concentration.

Wherein, the mounting hole 5 of 6-10 circumference uniform distribution is equipped on the disc 22 at the through-hole 4.

Wherein, it is equipped with screw hole 6 on the disc 22 at the through-hole 4, the center of the screw hole 6 to the spoke The distance at 22 center of plate is equal to the center of the mounting hole 5 to the distance at the 22 plate center of spoke.The screw hole 6 is disassembly vehicle The process screw hole used when wheel.

The mobility of the milling locomotive wheel of the utility model is good, and transition is convenient, is suitable for middle-size and small-size road surface operation.Milling machine The outer diameter required precision of the cylinder 21 of wheel is high, using lathe in machining.Press-fitting when in order to avoid press fitting 1 cracking of circle welds the cylinder 21 and press-fitting circle 1 using the method for butt welding, meets weld strength not less than 400N/mm2 Requirement.The internal diameter of the cylinder 21 will aspire for stability, consistency is good, using sizing enlarging die to the cylinder 21 into Row expanding.It avoids leading to the center bore deformation of wheel because the size of the press-fitting circle 1 is unstable after press fitting, influence and vehicle bridge Assembling.

All the embodiments in this specification are described in a progressive manner, the highlights of each of the examples are with The difference of other embodiments, the same or similar parts between the embodiments can be referred to each other.

In the description of the present invention, it should be understood that the orientation of the instructions such as term " on ", " one end " or position are closed System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, rather than The device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot It is construed as a limitation of the present invention.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is set Have ", " connection " shall be understood in a broad sense.It for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can It, can also be indirectly connected through an intermediary to be to be connected directly.Being fixedly connected can be to weld, be threadedly coupled and step up etc. often See technical solution.For the ordinary skill in the art, above-mentioned term can be understood in the utility model with concrete condition In concrete meaning.
