摘要： An air compressor includes a rotating device pivotally connected to a piston body. The rotating device includes a gear body and a counterweight. The gear body is formed together with a counterweight, wherein the counterweight is provided with a crankshaft corresponding to the center of the gear body and a crankpin placed at a distance from the crankshaft. The counterweight is horizontally divided into two integrally formed halves, including a left half and a right half, with a common line connected between the center of the crankshaft and the center of the crankpin, wherein the left half has a weight different from the right half, so that the piston body gathers more rotational momentum from the counterweight at BDC to facilitate upstrokes, so that the piston body can conduct reciprocating motion more smoothly, and thus the service life of the air compressor can be increased.

摘要： A tunnel-style crankshaft assembly is provided having counterweights that serve the purposes of retaining the axial motion of bearings and improving the balance of the crankshaft assembly as a result of having a structure of an increased radial profile. The counterweights can include a mass section and a bearing retaining section. When the counterweight is secured to a crank web, the mass section of the counterweight is axially spaced from a bearing assembly disposed around the web. Therefore, the mass section of the counterweight may extend radially beyond an inner race of the bearing assembly without contacting the bearing assembly's cage. The mass section of the counterweight does not extend radially beyond a radial envelope of a crankshaft support surface thereby permitting the crankshaft assembly to be slidingly inserted into the crankcase.
摘要翻译：提供了一种隧道式曲轴组件，其具有用于保持轴承的轴向运动并且由于具有增加的径向轮廓的结构而改善曲轴组件的平衡的目的。配重可以包括质量部分和轴承保持部分。当配重被固定到曲柄腹板上时，配重的质量部分与设置在腹板周围的轴承组件轴向间隔开。因此，配重的质量部分可以径向延伸超过轴承组件的内圈而不接触轴承组件的保持架。配重的质量部分不径向延伸超过曲轴支撑表面的径向包络，从而允许曲轴组件滑动地插入曲轴箱中。

摘要： A four-stroke, piston-powered internal explosion (“IE”) engine for providing power output through a rotating crankshaft. The IE engine includes an engine block having power cylinders formed therein for receiving working pistons, bearing means for supporting the crankshaft, and a crankshaft supported within the bearing means having an output end extending outside of the engine block and a plurality of offset power cranks. The IE engine further includes connecting rods operably coupled to the power cranks and configured to transfer power from the working pistons to rotate the crankshaft, and working pistons that are received into the power cylinders and operably coupled to the power cranks. Each working piston has a head end positioned adjacent to a cylinder head to form a compression chamber and is configured to receive power from an explosion of a compressed volume of air/fuel mixture located within the compression chamber, and to transfer the received power to the connecting rods. The IE engine is further configured so that the compressed volume of air/fuel mixture is substantially constant, and a peak compression ratio is maintained, from an angular position of the rotating crankshaft of at least 20 degrees prior to a TDC position of a compression stroke, to an angular position of at least 20 degrees after the TDC position of a power stroke, and prior to detonation.

摘要： A method of balancing a crankshaft includes connecting a torsion-absorbing pendulum to a cheek of the crankshaft, which is coupled to a crankpin. As the pendulum connected to the cheek has insufficient mass to balance the crankshaft, a lightening bore is formed through a bisection plane of the cheek. In forming the lightening bore, enough material is removed from the cheek so that the mass of the pendulum becomes sufficient to balance the crankshaft.

摘要： A mass-balancing transmission of an internal combustion engine (1) is provided, having a transmission housing (8) and a balancing shaft (6) with a bearing point (10, 11) at which the balancing shaft is mounted radially in a bearing seat (12, 13) of the balancing housing, and having an unbalanced section (9) which is formed in one part with the bearing point of the originally shaped balancing shaft. The bearing point is set back radially compared to the unbalanced section with the result that the diameter relationship: d2>d1 applies for the external envelope circle d1 of the bearing point and the external envelope circle d2 of the unbalanced section. Considered in the axial direction of the balancing shaft, the external envelope circle d2 of the unbalance section and the external envelope circle d1 of the bearing point extend offset to one another with an eccentricity of e.

摘要： A balancer shaft of an engine includes a pair of journal portions, a first stage balance weight and a second stage balance weight. The first stage balance weight is formed between the journal portions and eccentrically arranged with respect to an axis. The second stage balance weight is formed on a center part of the first stage balance weight in the axial direction and projects outward from the first stage balance weight in a radial direction. The balancer shaft has a recess portion on the opposite side of the eccentricity direction.
