Oil storage structure and connecting rod body

Abstract

The utility model belongs to the technical field of diesel engines and particularly relates to an oil storage structure and a connecting rod body. The device comprises a matching ring, and an oil storage groove is formed in the inner wall of the matching ring. A plurality of oil inlet holes are formed in the circumferential direction of the matching ring and communicate with the oil storage groove. When the matching ring is sleeved on the assembling face, lubricating oil enters the oil storage groove through the oil inlet hole. The oil storage groove is formed in the inner wall of the matching ring, so that an oil storage space is formed after the matching ring is matched with the bush to store lubricating oil, and sufficient lubrication between the piston pin and the connecting rod can be ensured when the lubricating oil does not splash in time when the diesel engine is initially started. When the diesel engine operates normally, the lubricating oil is collected through the oil inlet hole, the oil storage tank is in an overflow state for a long time, and when the diesel engine is in a non-starting state for a long time, the oil storage structure can still ensure that the lubricating oil cannot be lost, and sufficient lubrication between the piston pin and the connecting rod can still be ensured at the first time when the diesel engine is started again.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] It has been found through research that in the related art, only two oil inlet structures are designed at the small end of the connecting rod. When the diesel engine is initially started, started at low temperature, or started after a long time without starting, there is a risk of premature wear and abnormal wear due to the lubricating oil between the piston pin and the connecting rod not reaching in time.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0038] Based on the above research, as Figure 1As shown in the figure, an oil storage structure is provided in an embodiment of the present disclosure, including: a mating ring 1. An oil storage groove 2 is formed in the inner wall of the mating ring 1, and the oil storage groove 2 is arranged around the inner wall of the mating ring 1. The oil storage groove 2 is adapted to store lubricating oil. A plurality of oil inlet holes 11 are formed in the circumferential direction of the mating ring 1, and the oil inlet holes 11 are communicated with the oil storage groove 2. When the mating ring 1 is sleeved on the assembly surface, the lubricating oil can penetrate through the mating ring 1 through the oil inlet holes 11, enter the oil storage groove 2, and then flow from the oil storage groove 2 to the assembly surface to lubricate the mating ring 1 and the assembly surface of the parts to be assembled. The number of the above-mentioned mating rings 1 can be multiple. Preferably, the number of the oil inlet holes 11 is two, and the opening directions of the two oil inlet holes 11 are different, so that the lubricating oil can enter the oil storage groove 2 from multiple angles through the oil inlet holes. At the same time, in order to prevent the lubricating oil from flowing out of the oil inlet holes 11, resulting in a reduction in the amount of lubricating oil and insufficient lubrication effect, the oil inlet holes 11 are arranged upward. The above-mentioned oil storage structure can ensure that relative movement is required between the mating ring 1 and other parts to be assembled. However, in the case of initial movement, low-temperature movement or long-term non-movement, the mating ring 1 and the parts to be assembled are not fully lubricated, avoiding the risk of premature wear and abnormal wear.

[0039] As Figure 2 shown, at least one embodiment further provides a connecting rod body. Using the oil storage structure described above, the connecting rod body further includes a bushing 3. The oil storage structure is installed at the small end of the connecting rod body for storing lubricating oil. The bushing 3 is installed inside the mating ring 1. When it contacts the piston pin, the above-mentioned oil storage groove 2 forms a closed space, enabling the oil storage groove 2 to store lubricating oil. In order to allow the lubricating oil to flow to the contact surface between the bushing 3 and the piston pin to achieve the lubrication effect, a plurality of lubricating holes 31 are formed in the bushing 3. The lubricating holes 31 correspond to the oil storage groove 2, and the lubricating holes 31 penetrate through the inner and outer walls of the bushing 3. When the connecting rod body is assembled with the piston pin, the lubricating oil in the oil storage groove 2 lubricates the contact surface between the bushing 3 and the piston pin through the lubricating holes 31. In order to make the lubrication effect on the contact surface between the bushing 3 and the piston pin more uniform, preferably, the lubricating holes 31 are uniformly arranged along the circumferential direction of the bushing 3.

[0040] The above-mentioned connecting rod body can be applied to a diesel engine to ensure sufficient lubrication between the piston pin and the connecting rod when the lubricating oil has not splashed to the mating ring 1 in time during the initial start-up of the diesel engine. During the normal operation of the diesel engine, the collection of lubricating oil is completed through the mutual cooperation of the oil inlet holes 11 and the oil storage groove 2. The oil storage groove 2 is always in a full state for a long time. When the diesel engine is in a state of not being started for a long time, the oil storage structure can still ensure that the lubricating oil does not leak, and can still ensure sufficient lubrication between the piston pin and the connecting rod immediately when starting again.

[0041] Based on the above-mentioned ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
