Description

Technical Field

[0001] This utility model relates to the field of engine crankshaft technology, and in particular to a novel gas engine crankshaft device. Background Technology

[0002] The engine crankshaft is a key component in an internal combustion engine (such as a car engine). Also known as a crankshaft or crankshaft, the crankshaft is the main rotating part of the engine. After being fitted with connecting rods, it can support the reciprocating motion of the connecting rods and convert it into cyclic motion.

[0003] However, existing crankshafts are generally integrated units. If one of the balance weights is damaged, the entire crankshaft needs to be replaced, increasing maintenance costs and requiring improvement.

[0004] Therefore, this application proposes a novel crankshaft device for a gas engine to solve the problems in the prior art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel crankshaft device for gas engines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel gas engine crankshaft assembly includes a front axle end, a connecting mechanism, a crankshaft mechanism, and a rear flange, all mounted on the novel gas engine.

[0008] Multiple crankshaft mechanisms are provided between the front axle end and the rear flange, and the multiple crankshaft mechanisms, the front axle end, and the rear flange are all connected by the connecting mechanism;

[0009] The connecting mechanism includes a connecting rod, a collar, a locking block, a groove, a locking nut, and a slot. One end of the front axle end and the rear flange are each inserted into one end of one of the multiple connecting rods. Each end of the connecting rod has two mounting slots. Each of the four mounting slots has a locking block that is movably installed and engages with one end of the front axle end and the rear flange, respectively. Through the cooperative design between the front axle end, the crankshaft mechanism, the connecting mechanism, and the rear flange, not only can the maintenance of the crankshaft mechanism be facilitated, reducing maintenance costs, but the number of assembled crankshaft mechanisms can also be adjusted according to user needs, improving convenience and flexibility.

[0010] Specifically, both ends of the connecting rod are threaded with collars, and the inner side of each collar is in contact with one end of each of the four locking blocks, for blocking and limiting the four locking blocks.

[0011] Specifically, two grooves are formed on the inner side of each of the two collars, and the four grooves correspond to the four locking blocks respectively. During the rotation of the collar, the interaction between the grooves and the locking blocks causes one end of the locking block to move toward the groove and engage with it.

[0012] Specifically, both ends of the connecting rod are threaded with anti-loosening nuts, and one side of each of the two anti-loosening nuts abuts against the two collars to prevent the collars from loosening.

[0013] Specifically, slots are provided at both ends of the connecting rod, and one end of the front axle end and the rear flange are respectively inserted into the corresponding slots. Two slots are provided at one end of the front axle end and the rear flange, which are respectively adapted to the four locking blocks, so as to facilitate the connection between the front axle end and the rear flange and the connecting rod.

[0014] Specifically, the crankshaft mechanism includes a connecting rod journal, a balance plate, and a plug rod. Both ends of the connecting rod journal are fixedly connected to the balance plate, and one side of each of the two balance plates is fixedly connected to a plug rod. The two plug rods are respectively inserted into the corresponding slots. One end of one of the two plug rods is inserted into the other end of the connecting rod, so that the second slot corresponds to the locking block, and the plug rod is limited and fixed, thereby achieving the purpose of assembling the crankshaft mechanism.

[0015] Specifically, the two insert rods are respectively engaged with the connecting rods on both sides. Each of the two insert rods has two slots that are adapted to the four locking blocks. Through the interaction between the four locking blocks and the four slots, the insert rods on both sides of the connecting rod are limited and fixed.

[0016] Specifically, the width of the first groove is greater than the width of the locking block, which facilitates the threaded transmission between the collar and the connecting rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model discloses a novel crankshaft device for a gas engine. Through the cooperative design between the front axle end, crankshaft mechanism, connecting mechanism, and rear flange, it not only facilitates the maintenance of the crankshaft mechanism and reduces maintenance costs, but also allows for adjustment of the number of assembled crankshaft mechanisms according to user needs, improving convenience and flexibility.

[0026] Reference Figures 1-4 A novel gas engine crankshaft assembly includes a front axle end 1, a connecting mechanism 2, a crankshaft mechanism 3, and a rear flange 4, all mounted on the novel gas engine.

[0027] Multiple crankshaft mechanisms 3 are provided between the front axle end 1 and the rear flange 4, and the multiple crankshaft mechanisms 3, the front axle end 1 and the rear flange 4 are all connected by a connecting mechanism 2;

[0028] The connecting mechanism 2 includes a connecting rod 21, a collar 22, a locking block 23, a groove 24, a locking nut 25, and a slot 26. One end of the front axle end 1 and the rear flange 4 are each inserted into one end of one of the multiple connecting rods 21. Two mounting slots are provided at both ends of the connecting rod 21. Each of the four mounting slots 1 contains a locking block 23, which is respectively engaged with one end of the front axle end 1 and the rear flange 4. Through the cooperative design between the front axle end 1, the crankshaft mechanism 3, the connecting mechanism 2, and the rear flange 4, it is possible not only to facilitate the maintenance of the crankshaft mechanism 3 and reduce maintenance costs, but also to adjust the number of assembled crankshaft mechanisms 3 according to user needs, thereby improving convenience and flexibility.

[0029] In this method, both ends of the connecting rod 21 are threaded with collars 22. The inner side of the collars 22 is respectively in contact with one end of the four locking blocks 23 to block and limit the four locking blocks 23. Slider is fixedly connected to both sides of the four locking blocks 23. All eight sliders are slidably connected to the connecting rod 21. The effect of limiting the four locking blocks 23 can be achieved by the action of the eight sliders.

[0030] In this method, two grooves 24 are provided on the inner side of each of the two collars 22. The four grooves 24 correspond to the four locking blocks 23 respectively. During the rotation of the collar 22, the interaction between the grooves 24 and the locking blocks 23 causes one end of the locking block 23 to move toward the locking groove and engage with it. The width of the groove 24 is greater than the width of the locking block 23, which facilitates the threaded transmission between the collar 22 and the connecting rod 21.

[0031] In this configuration, both ends of the connecting rod 21 are threaded with anti-loosening nuts 25. One side of each anti-loosening nut 25 abuts against two collars 22 to prevent the collars 22 from loosening. Both ends of the connecting rod 21 are provided with slots 26. One end of the front shaft end 1 and the rear flange 4 are respectively inserted into the corresponding slots 26. One end of the front shaft end 1 and the rear flange 4 are provided with two slots that are respectively adapted to four locking blocks 23, which facilitates the connection between the front shaft end 1 and the rear flange 4 and the connecting rod 21.

[0032] In this method, the crankshaft mechanism 3 includes a connecting rod journal 31, a balance plate 32, and a plug rod 33. Both ends of the connecting rod journal 31 are fixedly connected to the balance plate 32, and one side of each balance plate 32 is fixedly connected to a plug rod 33. The two plug rods 33 are respectively inserted into the corresponding slots 26. One end of one of the two plug rods 33 is inserted into the other end of the connecting rod 21, so that the second slot corresponds to the locking block 23, and the plug rod 33 is limited and fixed, thereby achieving the purpose of assembling the crankshaft mechanism 3.

[0033] In this method, the two insert rods 33 are respectively engaged with the connecting rods 21 on both sides. Each insert rod 33 has two slots that are adapted to the four locking blocks 23. Through the interaction between the four locking blocks 23 and the four slots, the insert rods 33 on both sides of the connecting rod 21 are limited and fixed.

[0034] Working principle: In use, first insert one end of the front axle end 1 into the slot 26 of one end of the connecting rod 21, so that the first slot corresponds to the locking block 23. Then, by rotating the corresponding collar 22, it engages with the connecting rod 21 through threaded transmission, causing the collar 22 to rotate and move towards the end of the connecting rod 21. During the rotation of the collar 22, the interaction between the groove 24 and the locking block 23 causes one end of the locking block 23 to move towards the first slot and engage with it. At this time, the interaction between the locking block 23 and the first slot achieves the effect of quick installation of the front axle end 1. Afterwards, by rotating the corresponding anti-loosening nut 25, it abuts against the corresponding collar 22, thereby achieving the effect of limiting the collar 22.

[0035] Next, insert one end of one of the two insert rods 33 into the other end of the connecting rod 21, so that the second slot corresponds to the block 23. Then, repeat the above operation to limit and fix the insert rod 33.

[0036] Afterwards, by assembling multiple crankshaft mechanisms 3 through the above operations, not only can multiple crankshaft mechanisms 3 be assembled according to user needs, improving flexibility, but also, when one of the crankshaft mechanisms 3 is damaged, it can be replaced, greatly reducing maintenance costs.

[0037] Finally, one end of the rear flange 4 is inserted into the corresponding connecting rod 21 and fixed in place. In summary, this achieves the purpose of assembling the engine crankshaft.

[0038] The technological advancements of this invention compared to existing technologies are as follows: the cooperation of various components not only facilitates the maintenance of the crankshaft mechanism 3 and reduces maintenance costs, but also allows for adjustments to the number of assembled crankshaft mechanisms 3 according to user needs, improving convenience and flexibility. Moreover, the structure is simple and more practical.
