Novel crankcase

Abstract

The utility model provides a novel crankcase and belongs to the technical field of internal combustion engines. The crank case solves the problem that a crank case in the prior art, particularly a crank case in a high-power engine, is often abraded due to the fact that a connecting rod neck bears bending torsion load. The novel crankcase comprises a shell and a through hole formed in the shell and used for installing a connecting rod, an anti-abrasion ring playing an anti-abrasion role is arranged at an end opening of the through hole, the anti-abrasion ring is composed of a ring body, an anti-abrasion gasket and a fixed gasket, the anti-abrasion gasket and the fixed gasket are formed at the upper end and the lower end of the ring body respectively, and the anti-abrasion gasket and the fixed gasket are connected in a staggered mode. A fixing clamping block is arranged at the bottom of the fixing gasket, and a clamping groove allowing the fixing clamping block to stretch in and be clamped in is formed in the shell. The utility model has the advantage that the abrasion is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of internal combustion engines, relates to a crankcase, and particularly relates to a new type of crankcase. Background Technique

[0002] The crankcase is an important component of a piston engine. The pressure generated in the combustion chamber is transmitted to the crankcase through the cylinder block and the crankshaft. The crankcase also plays a role in fixing the engine. Therefore, the crankcase is required to have high stiffness and good noise and vibration reduction capabilities.

[0003] In the existing crankcases, especially those in high-power engines, wear problems often occur due to the bending and torsional loads borne by the connecting rod journals. These wear problems not only affect the performance of the engine but also increase the maintenance cost and downtime. Summary of the Invention

[0004] The purpose of the utility model is to provide a new type of anti-wear crankcase for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of crankcase includes a housing and a through hole opened on the housing for installing a connecting rod. The characteristic is that an anti-wear ring for anti-wear is provided at the port of the through hole. The anti-wear ring is composed of a ring body, an anti-wear washer and a fixing washer respectively formed at the upper and lower ends of the ring body, and the anti-wear washer and the fixing washer are connected in a staggered manner. A fixing block is provided at the bottom of the fixing washer, a clamping groove for the fixing block to extend into and be clamped is provided on the housing, bent blocks for clamping are respectively provided on the left and right sides of the fixing block, and bent grooves for the bent blocks to extend into and be clamped are provided on the inner wall of the clamping groove.

[0006] In the above new type of crankcase, the fixing block and the fixing washer are connected to each other through a fixing frame

[0007] In the above new type of crankcase, the fixing block is made of an elastic material and has an elastic effect.

[0008] Compared with the prior art, the new type of crankcase of the utility model realizes force balance, reduces wear and improves the overall durability by setting a unique anti-wear structure at the connecting rod connection, and reducing the friction effect of the crankcase contact surface through the anti-wear washer during operation.

[0012] In the figure, 1 is the housing; 2 is the through hole; 3 is the ring body; 4 is the wear-resistant washer; 5 is the fixing washer; 6 is the fixing block; 7 is the card slot; 8 is the bent block; 9 is the bent groove; 10 is the fixing frame. Detailed implementation mode

[0013] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0014] As Figure 1 , Figure 2 , Figure 3 shown, the novel crankcase includes a housing 1 and a through hole 2 opened on the housing 1 for installing a connecting rod. A wear-resistant ring is provided at the port of the through hole 2. The wear-resistant ring is composed of a ring body 3 and wear-resistant washers 4 and fixing washers 5 respectively formed at the upper and lower ends of the ring body 3. The wear-resistant washer 4 plays a role in preventing wear, and the wear-resistant washer 4 and the fixing washer 5 are connected in a staggered manner. A fixing block 6 is provided at the bottom of the fixing washer 5, and a card slot 7 for the fixing block 6 to extend into and be stuck is provided on the housing 1. Bent blocks 8 for clamping are respectively provided on the left and right sides of the fixing block 6, and a bent groove 9 for the bent blocks 8 to extend into and be clamped is provided on the inner wall of the card slot 7. When installing the wear-resistant ring, the fixing block 6 is completely embedded in the card slot 7, and the bent blocks 8 are matched with the bent grooves 9 to fix the wear-resistant ring. The unique clamping structure of the bent blocks 8 can prevent the wear-resistant ring from suddenly falling off during movement and firmly clamp it on the housing 1.

[0015] Further details, the fixing block 6 and the fixing washer 5 are connected to each other through a fixing frame 10, and the fixing block 6 is stabilized through the fixing frame 10.

[0016] Further details, the fixing block 6 is made of an elastic material and has an elastic effect. The use of the elastic material facilitates the disassembly and assembly of the fixing block 6 and avoids the phenomenon of jamming.

[0017] The specific embodiments described herein are only illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0018] Although terms such as housing 1, through hole 2, ring body 3, anti-wear washer 4, fixing washer 5, fixing block 6, card slot 7, bent block 8, bent groove 9, fixing frame 10 are used more frequently in this text, the possibility of using other terms is not excluded. These terms are only used to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
