Abstract
The utility model relates to the technical field of a driving chain, in particular to a high-intensity wear-resistant pin shaft arranged on a transporting chain. The partial outer surface layer of the pin shaft forms a high-frequency quenching layer by a high-frequency induction quenching process, the radial cross section of the high-frequency quenching layer is in a crescent shape to reinforce intensity and wear resistance and ensure toughness, and the utility model is more practical.
Description
Technical field
The utility model relates to the drive chain technical field, a kind of high-strength abrasion-proof bearing pin on the Conveying chains.
Background technique
At present, the use of Conveying chains is very extensive, and especially on the engineering chain, the constituent element of Conveying chains comprises bearing pin, yet the intensity of most of bearing pin and wear resistance are undesirable, and the bearing pin of high strength, high abrasion has lacked toughness.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of high-strength abrasion-proof bearing pin is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of high-strength abrasion-proof bearing pin, the part outer surface layer of bearing pin is processed to form the high frequency hardening layer by high-frequency induction hardening, the radial cross-sectional shape of high frequency hardening layer is a crescent shape, just form a side advantages of high strength, prevented the low characteristics of toughness of bearing pin.
The beneficial effects of the utility model are, a kind of high-strength abrasion-proof bearing pin of the present utility model, and its integrally-built wear resistance is good, intensity is high, and good toughness is arranged.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the comparison structure schematic representation of a kind of high-strength abrasion-proof bearing pin of the utility model;
Fig. 2 is the structural representation of a kind of high-strength abrasion-proof bearing pin of the utility model.
1. high frequency hardening layer, 2. bearing pins among the figure.
Embodiment
A kind of high-strength abrasion-proof bearing pin of preferred forms as shown in Figure 1 and Figure 2, the part outer surface layer of bearing pin 2 is processed to form high frequency hardening layer 1 by high-frequency induction hardening, the radial cross-sectional shape of high frequency hardening layer 1 is a crescent shape, the local strength and the wear resistance of bearing pin have been strengthened like this, also guaranteed simultaneously its toughness, very practical.
