Description

Speed reducer hand mechanism that can commutate

Technical Field

The utility model relates to a speed reducer equipment field, concretely relates to speed reducer hand mechanism that can commutate.

Background

The speed reducer driving mode is normally motor driving, and the auxiliary hand-cranking mode is used for carrying out hand-cranking to rotate when needed. However, at present, the end of the input rotating shaft of the speed reducer is directly driven by the hand handle, but the hand handle cannot be driven by the direct mode at all in some installation occasions of the speed reducer, so that a scheme is needed to solve the problem.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a speed reducer hand mechanism that can commutate, the design is simple, convenient to use.

The technical scheme of the utility model:

a reversible hand-operated mechanism of a speed reducer comprises a motor, a reduction gear box and a hand-operated mechanism, wherein the front end of the motor is in driving connection with an input rotating shaft of the reduction gear box, one end part of the input rotating shaft is provided with a separable hand-operated mechanism, the hand-operated mechanism is a reversible hand-operated mechanism and comprises a bracket and a driving bevel gear, driven bevel gear, the pivot, the support mounting is in reduction gear's the box outside, the design has the pivot in the support, install drive bevel gear and be located one side in the support in the pivot, the tip of reduction gear's input pivot stretches into in the support and installation driven bevel gear above the tip, the design has annular boss in the pivot and is located the support opposite side, the spring housing is in the pivot and one end top is on annular boss, the other end top is on the support inside wall, the both ends of pivot stretch into the support outside and be close to the one end design of drive bevel gear and have the crank connector.

The support include riser and diaphragm, two risers are installed perpendicularly respectively at the both ends of diaphragm, form U type frame, the pivot is rotatable to be installed on two risers and the pivot is equipped with the bush between the riser, the diaphragm passes through the box outside of screw fixed mounting at reduction gear box.

The utility model has the advantages that the design is simple, and convenient to use adopts the utility model discloses a hand mechanism can commutate, the support mounting direction is can all around the rotation transform installation fixed, and the pivot just can realize four directions like this and select the installation, than single direct drive in the past has gone out more choices, satisfies speed reducer installation needs, solves unable hand technical problem.

Detailed Description

Referring to the attached figures 1-3, a reversible hand-operated mechanism of a speed reducer comprises a motor 1, a speed reduction gear box 2 and a hand-operated mechanism, wherein the front end of the motor 1 is in driving connection with an input rotating shaft 3 of the speed reduction gear box 2, one end part of the input rotating shaft 3 is designed with a separable hand-operated mechanism, the hand-operated mechanism is a reversible hand-operated mechanism and comprises a support 4, a driving bevel gear 5, a driven bevel gear 6 and a rotating shaft 7, the support 4 is arranged outside a box body 21 of the speed reduction gear box, the rotating shaft 7 is designed in the support 4, the driving bevel gear 5 is arranged on the rotating shaft 7 and is positioned at one side in the support 4, the end part of the input rotating shaft 3 of the speed reduction gear box extends into the support 4, the driven bevel gear 6 is arranged on the end part, an annular boss 8 is arranged on the rotating shaft 7 and is positioned at, and a crank connecting head 10 is arranged at one end of the rotating shaft 7, which extends into the outer side of the bracket 4 and is close to the driving bevel gear 6.

The support 4 include riser 41 and diaphragm 42, two risers 41 are installed perpendicularly respectively at the both ends of diaphragm 42, form U type frame, the pivot 7 is rotatable to be installed on two risers 41 and be equipped with bush 43 between pivot 7 and the riser 41, diaphragm 42 passes through the screw fixed mounting in reduction gear's the box 21 outside.

The utility model discloses during the use, the support is installed the direction and is selected according to hand driven needs, the diaphragm of support lower extreme is fixed through the screw connection with reduction gear box's box, normally four screw hole designs on the box and four screw holes constitute the square, correspond four through-holes of design on the support, the diaphragm of support bottom is rotatory 90 degrees at every turn and all can correspond and install on the box, the transform direction also is followed to the pivot of installing in the support like this, can confirm the mounted position according to actual installation needs, ensure that hand (hold) can block on the crank connector of pivot one end, can hand drive, avoid other not good hand drive position. When the hand-cranking driving is needed, a sleeve opening at the lower end of a hand-cranking handle is clamped outside a crank connector, a forward force is applied to the crank in the hand-cranking process, the force is applied to a rotating shaft, the rotating shaft overcomes the spring force and slides forwards again, a driving bevel gear and a driven bevel gear are meshed with each other, then the crank is rotated simultaneously, the rotating shaft is driven to rotate, the rotating shaft drives a driving bevel gear to rotate, the driving bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives an input rotating shaft of a reduction gear box to rotate, and therefore the whole speed reducer is driven to; when not using, the handle is taken off to the handle, and the outside ejecting reset of spring handle pivot, initiative bevel gear and driven bevel gear throw off, can not influence during motor drive the utility model discloses a hand mechanism. The model of the speed reducer is SZJRV 30/63A.
