Description

Cranked link chain is used in transmission
Technical field
The utility model provides a kind of transmission to use cranked link chain, is specially a kind of high 3618 types heavy duty cranked link chain of transmission, bearing load that is used for.
Background technique
Cranked link chain is widely used in low-speed heave-load, the transmission of impact is arranged, and is specially adapted to oil-well rig, power shovel, building machinery, track-laying vehicle, liquid stirrers, sewage disposal device, textile industry with in the equipment such as mangler, and is of many uses.Existing 3618 type cranked link chains mainly are made up of cranked plate, sleeve, roller, bearing pin and lock pin, and sleeve and bearing pin are installed on the narrow end and the wide end of bent plate chain link respectively.In use, the phenomenon that roller can't be rotated by two cranked plate asphyxias by external pressure on the chest and abdomen often takes place; In the chain assembling process; The center line of two cranked plates is not usually in same plane; Cause bearing pin to wear the pin difficulty; Cause the reason of above-mentioned phenomenon to be that sleeve is a cylindrical shape, columnar sleeve had not both had axial limiting when being connected with two cranked plates do not have radially spacingly yet, and the narrow end inner width of bent plate chain link is wayward.In addition because the influence of the resilience of cranked plate in the press-bending process, the narrow end assembling of accumulated error, chain link in making; The wide end inner width of chain and narrow end are outer wide inconsistent; Matching gap is excessive and can't adjust between the two; Therefore often there is axial motion between the two adjacent bent plate chain links, causes the function of use of whole chain poor.
Summary of the invention
The utility model provides a kind of transmission to use cranked link chain, has solved existing transmission and has been prone to by asphyxia by external pressure on the chest and abdomen, wears shortcomings such as pin difficulty, whole chain function of use difference with the cranked link chain roller.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
Cranked link chain is used in a kind of transmission, comprises the bent plate chain link of serial connection successively at least, and an end of bent plate chain link is wide end; The other end is narrow end, and the bent plate chain link comprises cranked plate, bearing pin, roller and sleeve, and sleeve is installed on the narrow end of bent plate chain link through the sleeve hole on the cranked plate; Roller sleeve is on sleeve, and one of the pin shaft hole on two cranked plates is a circular hole, and another is a non-circular hole; Bearing pin is installed on the wide end of bent plate chain link through pin shaft hole; One end of bearing pin is a spindle nose, and the position adjacent with spindle nose is big end, and big end is complementary with non-circular hole and is positioned at non-circular hole; The nut that the other end of bearing pin is provided with screw thread and matches with screw thread, the bearing pin of a bent plate chain link passes the sleeve of another bent plate chain link in the adjacent two bent plate chain links.
Nut on the bearing pin is the hexagonal slotted nut, and the end that bearing pin is provided with screw thread also is provided with the hole and is used for pinning the cotter pin that the hexagonal slotted nut prevents its rotation, and cotter pin is positioned at the hole of the groove and the bearing pin of hexagonal slotted nut; The left side section of sleeve is equipped with two planes with right section, and two plane sizes are identical and distribute up and down, and two sections are complementary about the shape that the left side section of sleeve and right section are positioned at sleeve hole and sleeve hole and sleeve, and the stage casing is between left side section and the right side section, for cylindric.
Cranked link chain is used in the transmission that the utility model provides, screw thread that an end of bearing pin is provided with and hexagonal slotted nut, and the inner width that can regulate chain pitch width end makes itself and narrow end wide being consistent outward, and two adjacent link cooperate closely, no axial motion; The cotter pin that is positioned at the groove of hexagonal slotted nut can prevent that the hexagonal slotted nut from rotating, and makes the wide end inner width of bent plate chain link remain at a fixed value.Again because the left side section of sleeve be non-circular with right section, and the sleeve stage casing is cylindric, the center line that had therefore both guaranteed two cranked plates has guaranteed again between two cranked plates that no axial motion can the asphyxia by external pressure on the chest and abdomen roller, the excellent working performance of putting in order chain in same plane.
Description of drawings
The transmission that Fig. 1 provides for the utility model is with the overall structure schematic representation of cranked link chain;
Fig. 2 is the design of part schematic representation of bent plate chain link;
Among the figure, 1-cranked plate, 2-bearing pin, 3-roller, 4-sleeve, 5-pin shaft hole, 6-sleeve hole, 7-spindle nose, the big end of 8-, 9-screw thread, 10-hexagonal slotted nut, 11-cotter pin.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The transmission that the utility model provides is as shown in Figure 1 with the overall structure of cranked link chain, is made up of the bent plate chain link that is connected in series successively, and an end of bent plate chain link is wide end, and the other end is narrow end, and one narrow end is connected with another wide end in the two adjacent bent plate chain links.The design of part schematic representation of bent plate chain link is as shown in Figure 2, and it is circular hole with 5 one of pin shaft holes on sleeve hole 6, two cranked plates 1 that the position that two cranked plates 1 are positioned at wide end and narrow end is respectively equipped with pin shaft hole 5, and another is a non-circular hole.Roller 3 is enclosed within on the sleeve 4; Sleeve 4 is installed on the narrow end of bent plate chain link through sleeve hole 6, and sleeve is divided into left side section, stage casing and right section, and wherein the stage casing is between left side section and right section and be cylindric; Sleeve left side section is equipped with two planes with right section; Identical and the distribution up and down of two plane sizes, the left side section of sleeve 4 all is positioned at sleeve hole 6 with right section, and the left side section of the shape of sleeve hole 6 and sleeve 4 is complementary with right section.Bearing pin 2 is installed on the wide end of bent plate chain link through pin shaft hole 5, and an end of bearing pin 2 is a spindle nose 7, with spindle nose 7 adjacent positions be big end 8, hold 8 to be complementary greatly with non-circular hole; The nut that the other end of bearing pin 2 is provided with screw thread 9 and matches with screw thread 9, nut adopts hexagonal slotted nut 10 in the present embodiment; The end that bearing pin 2 is provided with screw thread 9 also is provided with the hole and is used for pinning the cotter pin 11 that hexagonal slotted nut 10 prevents its rotation, and cotter pin 11 is positioned at the groove of hole and hexagonal slotted nut 10.In whole chain, the sleeve 4 of a bent plate chain link is enclosed within on the bearing pin 2 of another bent plate chain link in the adjacent two bent plate chain links, and is as shown in Figure 1.
Cranked link chain is used in the transmission that the utility model provides, screw thread that an end of bearing pin is provided with and hexagonal slotted nut, and the inner width that can regulate chain pitch width end makes itself and narrow end wide being consistent outward, and two adjacent link cooperate closely, no axial motion; The cotter pin that is positioned at the groove of hexagonal slotted nut can prevent that the hexagonal slotted nut from rotating, and makes the wide end inner width of bent plate chain link remain at a fixed value.Again because the left side section of sleeve be non-circular with right section, and the sleeve stage casing is cylindric, the center line that had therefore both guaranteed two cranked plates has guaranteed again between two cranked plates that no axial motion can the asphyxia by external pressure on the chest and abdomen roller, the excellent working performance of putting in order chain in same plane.
