Abstract
The utility model provides a high performance planetary reducer, which comprises a housin, be equipped with the planet carrier in the casing, the casing with be connected with the sealing washer between the planet carrier, shells inner wall is equipped with the draw-in groove, the sealing washer includes interconnect's joint piece and sealed piece, the joint piece with the draw-in groove joint, sealed piece is equipped with the air cavity. The clamping groove is clamped with the clamping block to realize the fixation of the sealing ring; the air cavity is filled with air, when the sealing ring is connected with the planet carrier, the sealing block is compressed, the volume of the air cavity is reduced, the air pressure is increased, and the sealing block and the planet carrier are in a pressing state, so that the sealing property is improved; even if the sealing block is abraded, the sealing block and the planet carrier can be kept in a pressing state under the action of air pressure in the air cavity, so that the service life of the sealing ring is prolonged, and the replacement frequency is reduced.
Description
Technical Field
The utility model relates to a speed reducer technical field specifically is a high performance planetary reducer.
Background
The planetary reducer is an industrial product with wide application, and can reduce the rotating speed of a motor and increase the output torque. An inner gear ring is tightly combined on a gear box shell, a sun gear driven by external power is arranged in the center of a ring gear, and a planetary gear set formed by three gears which are equally divided and combined on a tray is arranged between the inner gear ring and the ring gear; when the power on the input side drives the sun gear, the planetary reducer can drive the planetary gear to rotate and revolve along the center of the inner gear ring, and the planetary gear rotates to drive the output shaft to output power. There is a planetary reducer, realizes sealedly through the mode of being connected the sealing washer between planet carrier and the casing, and the sealing washer is worn and torn easily, need unpack apart the box and just can change, and the process is loaded down with trivial details, consumes time long.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problems that a traditional planet speed reducer sealing ring is easy to wear, the replacing process is complex, and time consumption is long are solved.
The utility model provides a high performance planetary reducer, which comprises a housin, be equipped with the planet carrier in the casing, the casing with be connected with the sealing washer between the planet carrier, shells inner wall is equipped with the draw-in groove, the sealing washer includes interconnect's joint piece and sealed piece, the joint piece with the draw-in groove joint, sealed piece is equipped with the air cavity.
The clamping groove is clamped with the clamping block to realize the fixation of the sealing ring; the air cavity is filled with air, when the sealing ring is connected with the planet carrier, the sealing block is compressed, the volume of the air cavity is reduced, the air pressure is increased, and the sealing block and the planet carrier are in a pressing state, so that the sealing property is improved; even if the sealing block is abraded, the sealing block and the planet carrier can be kept in a pressing state under the action of air pressure in the air cavity, so that the service life of the sealing ring is prolonged, and the replacement frequency is reduced.
Furthermore, the clamping groove is T-shaped, and the clamping block is of a T-shaped structure. By the design, the sealing ring is clamped more firmly and is not easy to fall off and shift.
Furthermore, the end face of the sealing block connected with the planet carrier is arc-shaped. Due to the design, the sealing block is easier to deform, and the sealing performance of the sealing block and the planet carrier is improved.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is an enlarged view at A in FIG. 1;
in the figure: 1. a housing; 2. a planet carrier; 3. a seal ring; 11. a card slot; 31. a clamping block; 32. a sealing block; 33. an air cavity.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to a high-performance planetary reducer, including casing 1, be equipped with planet carrier 2 in the casing 1, be connected with sealing washer 3 between casing 1 and the planet carrier 2, as shown in fig. 2, the casing 1 inner wall is equipped with T-shaped draw-in groove 11, sealing washer 3 includes joint piece 31 and the sealing block 32 of interconnect, joint piece 31 is the T-shaped structure and with draw-in groove 11 joint to make the joint of sealing washer 3 more firm, be difficult for droing, shifting; the sealing block 32 is provided with the air cavity 33, and the end face of the sealing block 32 connected with the planet carrier 2 is arc-shaped, so that the sealing block 32 is more easily deformed, and the sealing performance of the sealing block 32 and the planet carrier 2 is improved.
The clamping groove 11 is clamped with the clamping block 31 to fix the sealing ring 3; the air cavity 33 is filled with air, when the sealing ring 3 is connected with the planet carrier 2, the sealing block 32 is compressed, the volume of the air cavity 33 is reduced, the air pressure is increased, and the sealing block 32 and the planet carrier 2 are in a pressing state, so that the sealing property is improved; even if the sealing block 32 is abraded, the sealing block 32 and the planet carrier 2 can still keep a pressing state under the action of air pressure in the air cavity 33, so that the service life of the sealing ring 3 is prolonged, and the replacement frequency is reduced.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
