Abstract

The utility model relates to a reciprocating piston diesel locomotive, which is a motor composed of a piston and rack bars. The utility model usually comprises the piston, a cylinder, an air pressure cylinder body, the rack bars, a gear and a transmission shaft. The utility model also comprises an arc swing rack member which is an oblong metal plate block. The arc swing rack member has two sector holes which are symmetrical up and down. The middle of the two sector holes is hollowed out. The left and the right of one side of the member are fixed with rack bars. The gear is arranged in the middle of the member. The lower end of the piston rod is additionally provided with a rectangular guide frame. The rectangular guide frame and the piston are integrated. The arc swing rack member is arranged in the rectangular guide frame. When the piston has up and down reciprocating movement, the gear and the rack bars have engaged movement. The utility model has the advantages of light weight, high mechanical efficiency and smooth piston commutation. The utility model is suitable for providing a power source for industrial and agricultural departments.

Description

Piston diesel locomotive

The utility model belongs to stroke piston combustion engine, is the motor that is connected to feature with piston and bent axle.

Existing stroke piston combustion engine adopts a partial gear and a pair of tooth bar to replace crankshaft ﹠ connecting, drives the d-axis rotation with piston and replaces crankshaft rotating.CN1061073A internal-combustion engine for example, when its shortcoming was that piston is done upper and lower to-and-fro motion to the topmost part or foot, gear and cylinder body top or bottom easily bumped, and the piston commutation is unstable, influences reciprocating motion of the pistons.

The purpose of this utility model is to design the gear and the rackwork that have drawing strickle guide, arc pendulum rack member to replace existing simple gear and rackwork, makes the piston commutation steadily, flexibly.

Referring to Fig. 1, the utility model is achieved in that sets up arc pendulum rack member (9) in the cylinder body of calming the anger of existing internal-combustion engine, two tooth bars (10) are fixed on the arc pendulum rack member; Set up a rectangle drawing strickle guide (8) at piston-rod lower end, rectangle drawing strickle guide and piston rod are one.Arc pendulum rack member is placed in the drawing strickle guide, and gear is placed in the middle of two tooth bars.When piston was done upper and lower to-and-fro motion, piston rod, drawing strickle guide drove the upper and lower motion of arc pendulum rack member, and this moment, gear rotated between two tooth bars, drove transmission shaft and rotated.

Below in conjunction with drawings and Examples the utility model is further described:

The positive generalized section of Fig. 1 the utility model.

Fig. 2 the utility model side generalized section.

Fig. 3 the utility model gear structure schematic representation.

Fig. 4 the utility model arc pendulum rack member schematic representation.

Referring to Fig. 1, Fig. 2 and Fig. 4, a kind of stroke piston combustion engine, comprise port (1), cylinder head (2), piston (3), seal ring (5), cylinder (4), the cylinder body (7) of calming the anger, piston rod (6), tooth bar (10), gear (11), transmission shaft (12), it is characterized in that also comprising arc pendulum rack member (9), it is a rectangular metal plate, on, following symmetry has fan-shaped hole, hollowed out in the middle of the two fan-shaped holes, on an arc pendulum rack member left side, on the right bi-side spring eye (16) is arranged, in balance spring (14) is housed, on arc pendulum rack member one a side left side, the right is fixed with tooth bar (10), and gear is placed in the middle of two tooth bars; Also be provided with rectangle drawing strickle guide (8) at piston-rod lower end, with piston rod be one, arc pendulum rack member is placed in the drawing strickle guide, is connected with key (13) between transmission shaft and the gear.Respectively there is a bearing (18) at the transmission shaft two ends, are installed in the cylinder body middle part of calming the anger.When internal combustion engine was done upper and lower to-and-fro motion, wheel and rack was done gear motion.When piston during near the topmost part or foot, gear tooth and tooth bar break away from engagement.Because inertia, the no toothed portion of gear goes to fan-shaped circular arc place and the slip of fan-shaped circular arc suits, and be rotated further, make the engagement of gear tooth and another tooth bar again, piston reverses direction motion this moment, drive the gear teeth again and nibble bar and do gear motion, drive transmission shaft and be rotated further, transmission shaft is rotated incessantly.Screw (17) is used for fastening drawing strickle guide and connects.

Among the embodiment, be provided with spill chute (15) at the left and right inwall of the cylinder body of calming the anger (7), drawing strickle guide is placed in the spill chute, and when piston was done upper and lower to-and-fro motion, drawing strickle guide is upper and lower slip in chute.

Referring to Fig. 3, the gear that the utility model uses is partial gear, and gear teeth thickness is 1/2～2/3 of gear thickness.Gear does not have the profile and the fan-shaped hole tangential of toothed portion and closes.

Should be pointed out that arc pendulum rack member can take place to move to the left or to the right when piston arrives during to the topmost part or foot, make to be contained in the balance spring of drawing strickle guide in left and right and to be compressed or to stretch out, guarantee that the wheel and rack engagement is good, make the piston reciprocating reversing steady.

The utility model is simple in structure, and piston, tooth bar, gear engagement are done arc pendulum orbiting motion.During system outside output power, piston moves on to foot from the topmost part, and the top of rack and pinion is engaged to the end of tooth bar, remains maximum moment output, has improved mechanical efficiency, compares weight saving 30% with the internal-combustion engine of identical power.
