Abstract
The invention discloses an assembling method for a bogie wheel disc assembly of a tracked vehicle. The assembling method is characterized by comprising the following steps: concave connecting holes are formed in a wear resistant steel ring; bolt holes which are aligned to the concave connecting holes are formed in a bogie wheel; the wear resistant steel ring is fastened and connected to the bogie wheel through fastening bolts; the concave connecting holes in the wear resistant steel ring are sealed through welding. The bogie wheel is made of aluminum alloy or magnesium alloy materials, and the wear resistant steel ring is made of 38CrSi steel. A special connection mode combining the threaded mechanical connection and the welding and fastening sealing enables the bogie wheel and the wear resistant steel ring to be firmly combined into a whole to form the bogie wheel disc assembly. Compared with the prior art, the method has the advantages that the firmness of the connection of the parts made of two kinds of materials is higher, and the falling-off is prevented; the surface is complete and free of assembling traces, and the quality is high; and the impact resistant performance of the parts manufactured according to the process is far better than that of the parts manufactured according to the conventional process, and a technical support is provided for further improving the motor performance of the tracked vehicle.
Description
Technical field
The present invention relates to a kind of assembly method of steel ring, be specifically related to the assembly method of the wear-resisting steel ring of a kind of continuously tracked vehicle bearing wheed disc assembly, belong to trim designs technical field.
Background technology
Continuously tracked vehicle, such as crawler crane, crawler crane, crawler-tread tractor, crawler dozer etc., all can be applied to bearing wheed on their ground-engaging element.At present, it is all to adopt the cold and hot method press-fiting to inlay steel wear-resisting ring that cold-press moulding aluminum alloy or magnesium alloy substrate bearing wheed are produced, and the structure of the bearing wheed disc assembly obtaining as shown in Figure 1.The bearing wheed assembly that the method arrives, in extremely severe working environment, the steel wear-resisting ring of inlaying is easy to depart from, and causes walking failure, unstable product quality.
Due to the specific demand of continuously tracked vehicle, require bearing wheed disc assembly must there is very high intensity and resistance to abrasion, and require strong shock resistance.Thereby need to improve the manufacturing process of bearing wheed disc assembly.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of assembly method of continuously tracked vehicle bearing wheed disc assembly, the bearing wheed disc assembly being produced by the method has being connected firmly between higher intensity and wear-resisting steel ring and bearing wheed.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
An assembly method for continuously tracked vehicle bearing wheed disc assembly, is characterized in that, comprises the following steps:
(1), on wear-resisting steel ring, offer connection shrinkage pool, or directly form connection shrinkage pool when manufacturing wear-resisting steel ring blank;
(2), on bearing wheed, offer with aforementioned and be connected the bolt hole that shrinkage pool aligns;
(3), binding bolt through connecting shrinkage pool and bolt hole, is fastenedly connected wear-resisting steel ring and bearing wheed successively;
(4), that the connection shrinkage pool seam on wear-resisting steel ring is airtight.
The assembly method of aforesaid continuously tracked vehicle bearing wheed disc assembly, is characterized in that, aforementioned bearing wheed is made by aluminum alloy or magnesium alloy materials.
The assembly method of aforesaid continuously tracked vehicle bearing wheed disc assembly, is characterized in that, the degree of depth of the bolt hole of aforementioned bearing wheed is 30-50mm.
The assembly method of aforesaid continuously tracked vehicle bearing wheed disc assembly, is characterized in that, aforementioned wear-resisting steel ring is made by 38CrSi steel.
The assembly method of aforesaid continuously tracked vehicle bearing wheed disc assembly, is characterized in that, the angle of the opening of the connection shrinkage pool of aforementioned wear-resisting steel ring is 90 °.
Usefulness of the present invention is: adopt screw thread mechanical connection to add the fastening airtight special connection mode of welding, bearing wheed and wear-resisting steel ring are firmly combined into one, form bearing wheed disc assembly, compared with prior art, the Du Genggao that is connected firmly of bi-material parts, is not prone to and comes off; Surface is complete, and without assembling vestige, quality is good; The parts shock resistance of particularly manufacturing by this technological design, far away higher than current technology technology, provides technical guarantee for further improving the maneuvering performance of continuously tracked vehicle.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
With reference to Fig. 2 to Fig. 4, the assembly method of continuously tracked vehicle bearing wheed disc assembly of the present invention, adopts screw thread mechanical connection to add the fastening airtight special connection mode of welding, and bearing wheed and wear-resisting steel ring are firmly combined into one, form bearing wheed disc assembly, specifically comprise the following steps:
(1), by any means, manufacture wear-resisting steel ring 4 blanks, and be machined to and need size, wear-resisting steel ring 4 preferably adopts 38CrSi steel to make.Then on wear-resisting steel ring 4, offer connection shrinkage pool, or directly form and connect shrinkage pool when manufacturing wear-resisting steel ring 4 blank.The angle [alpha] that connects the opening of shrinkage pool is preferably 90 °.
(2), by any means, manufacture bearing wheed 3 blanks, and be machined to and need size, bearing wheed 3 preferably adopts aluminum alloy or magnesium alloy materials to make.Then on bearing wheed 3, offer and the bolt hole that is connected shrinkage pool and aligns, the degree of depth of bolt hole is preferably 30-50mm.
(3), by binding bolt 6 successively through connecting shrinkage pool and bolt hole, thereby wear-resisting steel ring 4 is fastenedly connected with bearing wheed 3.
(4), the connection shrinkage pool seam on wear-resisting steel ring 4 is airtight, i.e. the fastening airtight point 5 of welding shown in Fig. 2, then combination processing, reaches the requirement of bearing wheed disc assembly, completes whole operations.
As can be seen here, first bi-material parts adopt screw thread mechanical connection, and the firmness of resulting continuously tracked vehicle bearing wheed disc assembly is higher, is not prone to and comes off; Then the connection shrinkage pool of wear-resisting steel ring is carried out to seam airtight, product surface is complete, and without assembling vestige, quality is good.
