Description

Technical Field

[0001] The utility model relates to the technical field of gear transmission, and particularly relates to an adjusting component for a reversing control gear. Background Art

[0002] Gearboxes are widely used and usually have functions of clutch, speed increase, and speed reduction. A number of gears are arranged inside the gearbox to achieve speed regulation, and the control and transmission of mechanical actions are realized through the input shaft and the output shaft. Since the gearbox is applicable to various working conditions and has reliable operation stability, it can be applied to a variety of mechanical equipment that requires rotational transmission.

[0003] In the production practice, the applicant continuously improves the internal structure of the gearbox according to the needs, and designs an adjusting component for a reversing control gear, so that the input shaft can realize different output modes through the rotation switching of clockwise and counterclockwise directions to achieve the switching of control effects. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and provide an adjusting component for a reversing control gear. The technical solution adopted by the utility model is as follows:

[0005] An adjusting component for a reversing control gear includes a reversing plate and a first ratchet wheel and a second ratchet wheel arranged on both side surfaces of the reversing plate. First and second braking claws respectively cooperating with the first ratchet wheel and the second ratchet wheel are arranged on both side surfaces of the reversing plate. The cooperation between the braking claws and the ratchet wheels enables each ratchet wheel to rotate only in one direction. The first and second braking claws are rotatably connected to both side surfaces of the reversing plate. The reversing plate has a first operating state in which it rotates counterclockwise, and then drives the first ratchet wheel to rotate through the first braking claw while the second braking claw does not drive the second ratchet wheel to rotate. And the reversing plate has a second operating state in which it rotates clockwise, and then drives the second ratchet wheel to rotate through the second braking claw while the first braking claw does not drive the first ratchet wheel to rotate. The realization of one-way rotation by the cooperation of the above-mentioned ratchet wheels and braking claws is the prior art, and its principle will not be elaborated here.

[0006] Preferably, an elastic positioning member is arranged in cooperation with the braking claw. The elastic positioning member maintains the engagement between the braking claw and the ratchet wheel or maintains the tendency of the engagement between the braking claw and the ratchet wheel, that is: when the braking claw does not drive the ratchet wheel to rotate, the elastic positioning member maintains the tendency of the engagement between the braking claw and the ratchet wheel, but the braking claw slides and bounces along the outer periphery of the ratchet wheel; when the braking claw drives the ratchet wheel to rotate, the elastic positioning member maintains the engagement between the braking claw and the ratchet wheel so that the reversing plate drives the braking claw to drive the ratchet wheel to rotate.

[0007] Preferably, the elastic positioning member is a torsion spring, and the torsion spring is installed between the reversing plate and the braking claw.

[0008] Preferably, at least two braking claws arranged in pairs are distributed on each side of the reversing plate, and the two braking claws arranged in pairs are distributed on both sides of the ratchet wheel in a centrally symmetrical manner.

[0009] Preferably, the first ratchet and the second ratchet are respectively connected to the first gear set and the second gear set; the first ratchet is coaxially connected to at least one gear in the first gear set; the second ratchet is coaxially connected to at least one gear in the second gear set.

[0010] Preferably, the reversing plate is sleeved on the input shaft and linked with the input shaft, the first gear in the first gear set is coaxially linked with the first ratchet, the third gear in the second gear set is coaxially linked with the second ratchet, and the first gear, the first ratchet, the third gear and the second ratchet are all sleeved on the input shaft.

[0011] The beneficial effects of the utility model are as follows: when the adjustment component of the reversing control gear provided by the present invention is in use, by controlling the rotation direction of the reversing plate, the rotation of the first ratchet wheel and the rotation of the second ratchet wheel can be separately controlled. It can be applied to gears and gear transmission components that need to be separately controlled in rotation. Only by switching the rotation direction of the reversing plate clockwise and counterclockwise, two output control effects can be achieved respectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1

[0025] As Figures 1-6 shown, an adjustment assembly for a reversing control gear includes a reversing plate 21 and a first ratchet wheel 231 and a second ratchet wheel 232 disposed on both side surfaces of the reversing plate 21. First and second brake claws respectively cooperating with the first ratchet wheel 231 and the second ratchet wheel 232 are disposed on both side surfaces of the reversing plate 21, and the brake claw 22 cooperates with the ratchet wheel to enable each ratchet wheel to rotate only in one direction; the reversing plate 21 has a first operating state of rotating counterclockwise to drive the first ratchet wheel 231 to rotate through the first brake claw and not drive the second ratchet wheel 232 to rotate through the second brake claw, and, the reversing plate has a second operating state of rotating clockwise to drive the second ratchet wheel 232 to rotate through the second brake claw and not drive the first ratchet wheel 231 to rotate through the first brake claw.

[0026] In use, by controlling the rotation direction of the reversing plate 21, the rotation of the first ratchet wheel 231 and the second ratchet wheel 232 can be separately controlled. It can be applied to components with gears and gear transmissions that require separate and independent rotation control. Just by switching the rotation direction of the reversing plate 21 clockwise and counterclockwise, two output control effects can be respectively achieved.

[0027] Referring to Figure 3 、 4 , the brake claw 22 is also provided with an elastic positioning member 24, and the elastic positioning member 24 maintains the engagement of the brake claw 22 with the ratchet wheel or maintains the engagement tendency of the brake claw 22 with the ratchet wheel.

[0028] In this embodiment, the elastic positioning member 24 is a torsion spring, and the torsion spring is installed between the reversing plate 21 and the brake claw 22.

[0029] At least two pairs of brake claws 22 are distributed on each side of the reversing plate 21, and the two pairs of brake claws 22 are symmetrically distributed on both sides of the ratchet wheel.

[0030] The first ratchet wheel 231 and the second ratchet wheel 232 are respectively drivingly connected to the first gear set 3 and the second gear set 4; the first ratchet wheel 231 is coaxially drivingly connected to at least one gear in the first gear set 3; the second ratchet wheel 232 is coaxially drivingly connected to at least one gear in the second gear set 4.

The first gear set 3 includes a first gear 31 and a second gear 32 that are in driving cooperation, and the second gear set 4 includes a third gear 41, a fourth gear 42, and a fifth gear 43 that are in driving cooperation;

[0034] Taking the direction facing the first ratchet wheel 231 as the positive direction, when the input shaft 1 rotates counterclockwise, the reversing plate 21 has a first operating state of rotating counterclockwise and then driving the first ratchet wheel 231 to rotate counterclockwise through the brake claw 22 and making the second ratchet wheel 232 not rotate. At this time, the first gear 31 rotates counterclockwise and the second gear 32 rotates clockwise;

[0035] Rotate the input shaft 1 clockwise. The reversing plate 21 and the brake pawl 22 drive the second ratchet wheel 232 to rotate clockwise and the first ratchet wheel 231 not to rotate. At this time, the third gear 41 rotates clockwise, and the fourth gear 42 and the fifth gear 43 rotate counterclockwise.
