Abstract
The utility model provides a visual check ring of an elastic pin coupler, wherein a ring of round observation holes are arranged along the inner circle of the check ring; and the positions and the number of the observation holes correspond to those of pin ends inlaid on a jacket and an inner gear ring and blocked by the check ring. As the check ring is provided with the observation holes having the same positions and the number with the pins, the operational condition or damaged condition of a nylon pin can be directly observed from the external, thus not only being capable of reducing the trouble caused by disassembly check and saving manpower, material resources and time, but also being capable of finding the problems at any time and treating the problems in time, avoiding the phenomenon of coupler failure due to sheared nylon pin, and ensuring normal equipment running.
Description
Technical field
The utility model belongs to the transmission device field, relates in particular to a kind of visual back-up ring that is used for the elastic dowel pin shaft coupling outer ring.
Background technique
Elastic dowel pin shaft coupling is very extensive in the application of industrial field, and its easily damaged parts spring column pin is that nylon rod is made, and the nylon pin all shreds, and coupling will lose efficacy.Elastic dowel pin shaft coupling mainly is made up of inner ring, outer ring and back-up ring.Inner ring has external tooth, and the outer ring has internal tooth, is installed with many nylon pins between the inside and outside tooth after install inner ring and outer ring.Be enclosed within the outer annular retaining ring employing of inner ring and be threaded on the outer ring, and the termination of nylon pin is covered in.
Because annular retaining ring has covered the termination of nylon pin, therefore runnability and damaged condition that at all can't O﹠E nylon pin from the outside, not the Yin Nilong pin to occur to shred and cause the coupling failure phenomenon, directly influence the normal operation of whole drive system.For reducing causality loss, often coupling is carried out strip inspection with regard to needs, to guarantee the failure-free operation of equipment.And, therefore especially waste personnel and man-hour in the more occasion of coupling because this regular disintegration belongs to a kind of simple repetition behavior, more the operating rate to system produces influence greatly.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, and is effectively directly perceived, need not to disintegrate and just can observe out the state of nylon pin at any time rapidly, avoids the visual back-up ring of elastic dowel pin shaft coupling of breakdown loss.
Above-mentioned purpose realizes by following concrete scheme:
The visual back-up ring of a kind of elastic dowel pin shaft coupling is provided with the circular peep hole of a circle along circle in the back-up ring, the position of each peep hole be installed in overcoat and ring gear on and the pin tip position of being blocked by back-up ring corresponding one by one.
The quantity of described peep hole is identical with pin quantity.
The diameter of described peep hole is slightly less than pin termination diameter.
The beneficial effects of the utility model are:
Owing on back-up ring, offered and pin position, peep hole that quantity is identical, just can observe directly the runnability or the damaged condition of nylon pin from the outside, both can reduce the trouble that strip inspection brings, save effort and time; Can pinpoint the problems at any time again, in time be handled, avoid the nylon pin to shred and cause the coupling failure phenomenon, guarantee the normal operation of equipment.
Description of drawings
Fig. 1 is the elastic dowel pin shaft coupling outline drawing.
Fig. 2 is an elastic dowel pin shaft coupling pin erection drawing.
Fig. 3 is the visual back-up ring figure of elastic dowel pin shaft coupling.
Among the figure: outer ring 1, back-up ring 2, inner ring 3, pin 4, bolt hole 5, peep hole 6.
Embodiment
As seen from Figure 1, elastic dowel pin shaft coupling system is made of outer ring 1, back-up ring 2 and inner ring 3, is enclosed within inner ring 3 outer annular retaining rings 2 employings and is threaded on the outer ring 1.See that from Fig. 2 pin erection drawing inner ring 3 has external tooth, outer ring 1 has internal tooth, is installed with 14 nylon pins 4 between the inside and outside tooth after install inner ring 3 and outer ring 1, and along being processed with 14 bolts hole on the excircle of outer ring 1.Fig. 3 then can clearly reflect the shape of annular retaining ring 2.
The utility model mainly is that the interior round bur along back-up ring 2 has 14 circular peep holes 6, the quantity that is peep hole 6 is identical with the quantity of pin 4, the diameter of peep hole 6 then is slightly less than pin 4 termination diameters, open just correspondingly on the position of 14 pin 4 terminations the position of 14 peep holes 6, is beneficial to the inspection to pin 4.
Claims (3)
1. the visual back-up ring of elastic dowel pin shaft coupling is characterized in that, is provided with the circular peep hole of a circle along circle in the back-up ring, the position of each peep hole be installed in overcoat and ring gear on and the pin tip position of being blocked by back-up ring corresponding one by one.
2. the visual back-up ring of elastic dowel pin shaft coupling according to claim 1 is characterized in that the quantity of described peep hole is identical with pin quantity.
3. the visual back-up ring of elastic dowel pin shaft coupling according to claim 1 is characterized in that the diameter of described peep hole is slightly less than pin termination diameter.
