Abstract
The utility model relates to a connecting clamp ring for a chain rod and a pin shaft of a buried scraper conveyer, which is composed of a circular ring-shaped steel sheet 1 which is provided with an opening part, wherein, a pressing point 4 is arranged on an outer ring 2 of the steel sheet. The utility model is characterized in that the clamping ring has the advantages of wear resistance, little possibility of fall, convenient installation, and convenient replacement, and has the characteristics that after the utility model is assembled, the clamp ring is tightly matched with the pin shaft without relative rotation, and the outer contour forms a circular shape and can uniformly bear definite axial force. The utility model has the characteristics of simple structure and good reliability.
Description
The utility model is a kind of location collar that is used for embedded scraper transporter operation chain connecting link pin.
The locate mode that existing chain lever pin axle connects has: spring cotter (GB91-86), thread connection, but because the operation chain and the long-term contact friction of convey materials of embedded scraper transporter, easily cause spring cotter wear and rupture or coupling nut to come off to cause the bearing pin displacement and cause the embedded scraper transporter chain rupture accident.
The purpose of this utility model provides a kind of embedded scraper transporter chain lever pin axle simple in structure, good reliability and connects collar.
The purpose of this utility model is achieved in that a kind of embedded scraper transporter chain lever pin axle connects collar, and its keystone configuration is: it is made up of the circular steel disc 1 that opening part is set, and setting compresses a little 4 on the steel disc outer shroud 2.
The utility model provides a kind of safe and reliable bearing pin to connect locate mode, is characterized in that this collar is wear-resistant, difficult drop-off, and install and change conveniently.After the assembling, collar cooperates closely with bearing pin, and nothing relatively rotates, and outline is rounded, can be equably to be subjected to certain axial force.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model running condition structural representation.
Fig. 3 is the lateral plan of Fig. 2.
Among the figure: 1, steel disc, 2, outer shroud, 3, interior ring, 4, compress a little, 5, bearing pin.
A kind of embedded scraper transporter chain lever pin axle connects collar, and it is made up of the circular steel disc 1 that opening part is set, and setting compresses a little 4 on the steel disc outer shroud 2, and interior ring 3 is formed by connecting by multi-section circular arc.Adopt special-purpose diel through twice continuous drawing.
With reference to Fig. 1, this collar adopts the particular manufacturing craft drawing by the thick ordinary low-carbon steel of 5mm, proofreaies and correct after heat treatment, and being shaped, (Φ 20 for back collar opening
+ 0.28) be slightly larger than bearing pin fit diameter Φ 14 ± 0.1, be convenient to assembling.
With reference to Fig. 2, Fig. 3, special caliper is adopted in assembling, and collar is pinched, and pinches bayonet socket gap, back less than 2.5mm, and appearance profile is near circle, and interior ring 3 is stuck in outside the bearing pin 5.
Claims (1)
1, a kind of embedded scraper transporter chain lever pin axle connects collar, it is characterized in that it is made up of the circular steel disc (1) that opening part is set, and steel disc outer shroud (2) is gone up setting and compressed point (4).
