Problems solved by technology

However, neither the existing technology nor the theory has noticed that the eccentric rotor actually only guarantees the simple harmonic vibration of its center of circle, and in some cases it cannot guarantee the same simple harmonic vibration of the components driven by the rotor (such as the piston) and the Related problems caused by this, such as the distance between the inner end faces of the two pistons driven by the rotor cannot be kept constant, which affects the pressure of the medium in the equipment, and the influence of the ellipticity of the rotor due to inclination cannot be eliminated; in addition, the general disc rotor cannot change the amplitude of the vibration

Embodiment 1

[0055] Embodiment 1, the curved equipment 6 is sealed and fixedly connected with the piston guide cylinder 4 through flanges, bolts, and gasket assemblies. The equipment 6 can be installed vertically or horizontally (this example is vertically installed). The piston 10 passes The sealing element and the piston guide cylinder 4 form a sealing movable fit, and the outer end of the piston 10 (which may be a piston rod if necessary) is in point contact with the rotor 3 . The cylindrical rotor 3 is driven by a power device (such as a motor). Since the geometric axis of the rotor 3 has an angle α with its rotation axis 2, there is an eccentricity in the rotor 3. The rotation of the rotor 3 pushes the piston 10 to reciprocate up and down, so that the equipment 6 The cavity space, so that the medium in the device 6 oscillates. In this example, the outer end of the piston 10 (which may be the piston rod if necessary) is in point contact with the rotor 3, so the motion of the piston 10 ...

Embodiment 2

[0056] Embodiment 2, to overcome the ellipticity influence caused by the inclination of the rotor 3, keep the size of the inner cavity space of the device 6 (that is, the distance between the inner end faces of the two pistons 10) constant, and make the piston 10 and the center of the rotor 3 For the same simple harmonic vibration, a contact piece 12 perpendicular to the centerline of the piston 10 (or the axis of the rotor 3 or the rotating shaft 2) can be added to the outer end of the piston 10 (if necessary, the piston rod), and the contact piece 12 is formed by the contact piece 12 and the rotor 3. Tangential contact, all the other are with embodiment 1. refer to figure 1 , Figure 38 , Figure 39 with Figure 40 .

Embodiment 3

[0057] In Embodiment 3, the circular section rotor 3 in Embodiment 1 is replaced with a cam rotor 3, and the rest are the same as Embodiment 1. refer to figure 1 , Figure 43 . When the piston 10 is in contact with the cam rotor 3, several commonly used motion forms of the piston 10 are:

[0058] 1) Isokinetic motion

[0059] Push distance: return trip:

[0060] 2) Equal acceleration and deceleration motion

[0061] Thrust (set as constant acceleration): Return trip (set to constant deceleration):

[0062] 3) Sine acceleration motion

[0063] a δ 0 ( 2 π δ 0 δ )

[0064] 4) Cosine accelerated motion

[0065] u = πa 2 δ 0 ( π δ 0 ...

Abstract

The rotor machine has unchanged operating space. Technologically, the rotor machine is provided with two, one right and one left, pistons inside guide drum fixed on the machine, and two, one right and one left, rotor contacting separately to the right and the left pistons. One right contact part and one contact part are set between the each piston and each rotor for tangent contact, so as to maintain the operating space of the machine unchanged, eliminate the ellipticity error caused by rotor inclination and geometric error caused by point contact, and ensure strict simple harmonic vibration.

Description

technical field [0001] The invention relates to a mechanical device generating reciprocating motion by a rotor, belonging to the technical fields of mechanical principles and mechanisms. Background technique [0002] To generate an oscillating motion, an eccentric rotor can be used. As a mechanical device, the eccentric rotor can be used in many machines and equipment. However, neither the existing technology nor the theory has noticed that the eccentric rotor actually only guarantees the simple harmonic vibration of its center of circle, and in some cases it cannot guarantee the same simple harmonic vibration of the components driven by the rotor (such as the piston) and the Related problems caused by this, such as the distance between the inner end faces of the two pistons driven by the rotor cannot be kept constant, which affects the pressure of the medium in the equipment, and the influence of the ellipticity of the rotor due to inclination cannot be eliminated; in addi...
