Description

Control phase speed reducer continuously

Technical field

The utility model relates to the speed reducer of mechanical transmission fields, particularly relates to a kind of control phase speed reducer continuously.

Background technique

At present, on the market between the input shaft of the conical gear reducer of widespread usage and the output shaft phase relationship fix.Only this speed reducer is taken apart, readjusted the meshing relation between gear, otherwise be the phase relationship that can't change the relative input shaft of output shaft.

And in mechanical transmission, particularly when make-up machinery equipment, usually need the phase place of speed reducer input shaft and output shaft to regulate, even in equipment debugging and the phase relationship that also needs to regulate continuously between input shaft and the output shaft in service.

Summary of the invention

The purpose of this utility model provides a kind of control phase speed reducer continuously, and this deceleration function realizes that the phase relationship of input shaft and output shaft is adjustable continuously under the situation of not taking apart.

In order to achieve the above object, control phase speed reducer continuously of the present utility model, comprise input shaft, output shaft, input bevel gear, output bevel gear, bevel planet gear, bevel planet gear retainer and speed reducer casing, it is characterized in that: also comprise worm gear and worm screw;

Worm screw is installed on the speed reducer casing, worm gear is fixed on the bevel planet gear retainer, worm gear and worm meshing, bevel gear is installed on the input shaft in input, input bevel gear and bevel planet gear engagement, bevel planet gear and bevel planet gear retainer are for flexibly connecting bevel planet gear and the engagement of output bevel gear, the output bevel gear is fixedlyed connected with output shaft, and bevel planet gear retainer and speed reducer casing are slidingly connected.

Described worm gear and worm screw are a pair of worm and gear transmission.

Described input bevel gear, output bevel gear and bevel planet gear are straight bevel gear, spiral bevel gear or helical bevel gear.

Described bevel planet gear is two or four.

The support locating piece that described bevel planet gear retainer is input shaft, output shaft and bevel planet gear, input shaft and output shaft and bevel planet gear retainer flexibly connect, and worm gear is fixed on the bevel planet gear retainer.

Described speed reducer casing is the whole support connecting piece of control phase speed reducer continuously, and bevel planet gear retainer and speed reducer casing flexibly connect, and worm gear is installed on the speed reducer casing.

Described input shaft and output shaft are the input end and the output terminal of speed reducer, connect the input and output part of transmission respectively.

During work, the rotation of input shaft drives the input bevel gear and rotates, the input bevel gear is rotated and drives the bevel planet gear rotation, because turbine worm mechanism has auto-lock function, under the situation that worm gear does not rotate, does not have relative movement between speed reducer casing and the bevel planet gear retainer, bevel planet gear rotates and drives the rotation of output bevel gear, the output bevel gear is rotated and drives the output shaft rotation, and at this moment, the phase relationship between input shaft and the output shaft is fixed; When rotary worm, worm gear is also along with rotation, and the rotation of worm gear just drives the rotation of bevel planet gear retainer, the bevel planet gear retainer rotates and drives bevel planet gear rotation mounted thereto, bevel planet gear rotates and drives the rotation of output bevel gear, thereby makes the output bevel gear produce a phase increment, and the phase relationship between input shaft and the output shaft is that change has taken place, regulate worm screw continuously, can make the phase place between input shaft and the output shaft recur change.

Because worm and gear is easy to adjust, only need rotary worm just can realize, so the phase adjusted between input shaft and the output shaft is simple and convenient.

Control phase speed reducer continuously of the present utility model can realize that the phase relationship of input shaft and output shaft is adjustable continuously under the situation of not taking apart, regulate simple and convenient.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation.

Embodiment

The explanation of Fig. 1 mark: input shaft 1, output shaft 2, input bevel gear 3, output bevel gear 4, bevel planet gear 5, bevel planet gear retainer 6, speed reducer casing 7, worm gear 8, worm screw 9.

Referring to Fig. 1, the embodiment of control phase speed reducer continuously of the present utility model comprises input shaft 1, output shaft 2, input bevel gear 3, output bevel gear 4, bevel planet gear 5, bevel planet gear retainer 6, speed reducer casing 7, worm gear 8 and worm screw 9.

Worm screw 9 is installed on the speed reducer casing 7, worm gear 8 is fixed on the bevel planet gear retainer 6, worm gear 8 and worm screw 9 engagements, bevel gear 3 is installed on the input shaft 1 in input, input bevel gear 3 is to flexibly connect with bevel planet gear 5 engagements, bevel planet gear 5 with bevel planet gear retainer 6, bevel planet gear 5 and 4 engagements of output bevel gear, output bevel gear 4 is fixedlyed connected with output shaft 2, and bevel planet gear retainer 6 is slidingly connected with speed reducer casing 7.

Worm gear 8 and worm screw 9 are a pair of worm and gear transmission, and in an embodiment, its velocity ratio is 30.

In an embodiment, input bevel gear 3, output bevel gear 4 and bevel planet gear 5 all are straight bevel gear, and bevel planet gear 5 is two.
