Abstract
A driving mechanism of a piston comprises a cylinder body. A piston is matched with and is arranged in the cylinder, and a sealing element is arranged on the piston. The piston is connected with the driving mechanism. The driving mechanism is characterized in that the driving mechanism is a rack which is connected with the piston, the rack is engaged with a gear, a guiding device is arranged out of the rack, and the gear rotates in positive and reverse directions driven by power. Because the power directly acts on the center of the gear, the distance between the rack and the gear is short, and the generated transverse force component which makes the mutual attrition of the piston and the cylinder wall less, namely, the power lose is less, and the service life of the machine is long. The guiding device is arranged out of the rack to guarantee the smooth operation of the rack and the gear, and the transmission of power is reliable.
Description
Technical field
The utility model relates to a kind of lead agency of piston, belongs to mechanical transmission, can be widely used in liquid or gas boosting and conveying.
Background technique
In various internal-combustion engines or the pump series products, usually use cylinder body and piston and carry liquid or gas.Because piston is a kind of to-and-fro motion in the cylinder chamber, so prior art connect the piston rod of piston or connecting rod by crank arm, eccentric stiffener drives, crank arm, eccentric stiffener acts on piston after driving is center and two component of side direction, cross component force is big to the wear rate of piston and casing wall, power loss is many, and has influenced the working life of machine.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of piston little to the side direction active force of casing wall, the light abrasion of piston and casing wall, the piston lead agency of machine long service life.
The technological scheme of the lead agency of a kind of piston of the utility model is: comprise cylinder body, fitting piston in the cylinder body, Sealing is arranged on the piston, piston connecting band actuation mechanism, it is characterized in that described lead agency is the tooth bar that connects piston, rack and pinion is meshed, and tooth bar has guiding device outward, and gear drives forward and reverse rotation by power.
The lead agency of a kind of piston of the utility model connects tooth bar with piston, the rack and pinion engagement, and gear is driven by the power of forward with oppositely alternating motion.Make forward or reverse alternate rotation by the power driven gear during work, make the rack drives reciprocating motion of the pistons, carry liquid or gas.Because power acts directly on Gear center, the spacing of wheel and rack is little, and therefore the transverse component (transverse component rubs piston and casing wall mutually) that produces is little, and promptly power loss is little, the long service life of machine.Tooth bar has guiding device outward, can guarantee that rack and pinion operates steadily, and transferring power is reliable.
Description of drawings
Fig. 1 is the lead agency cross-sectional schematic of a kind of piston of the utility model.
Embodiment
The utility model discloses a kind of lead agency of piston, as shown in Figure 1, comprise cylinder body 1, fitting piston 2 in the cylinder body 1, and Sealing 3 is arranged on the piston, piston connecting band actuation mechanism, it is characterized in that described lead agency is the tooth bar 4 that connects piston 2, rack and pinion 5 is meshed, and tooth bar has guiding device outward, and gear drives forward and reverse rotation by power.Connect tooth bar 4 with piston 2, tooth bar 4 is driven by the power of forward with oppositely alternating motion with gear 5 engagements, gear 5.Make forward or reverse alternate rotation by power driven gear 5 during work, make tooth bar 4 drive pistons 2 to-and-fro motion, carry liquid or gas.Because power acts directly on gear 5 centers, gear 5 is little with the spacing of tooth bar 4, and therefore the transverse component (transverse component rubs piston and casing wall mutually) that produces is little, and promptly power loss is little, the long service life of machine.Outside the tooth bar 4 guiding device is arranged, can guarantee that rack and pinion operates steadily, transferring power is reliable, and guiding device can adopt guide sleeve 6 as shown in Figure 1, and guide sleeve is fixed on the cylinder body 1, also can adopt the guiding device of alternate manner.
Claims (1)
