Description

Compact transmission gear box

Technical Field

The utility model belongs to the technical field of drive gear box, concretely relates to compact drive gear box.

Background

The heat dissipation of the gearbox is generally realized by the convection of air and the surface of the gearbox body. In order to realize that the smaller gear box volume can optimize and improve the structure of the gear box by using a more compact structure, when the compact gear box transmits high power, the temperature of lubricating oil of the gear box is influenced because the self heat dissipation area inside the gear box is limited, good heat conduction cannot be realized, and a good heat dissipation effect cannot be realized, and the gear and the bearing cannot be guaranteed to have good lubrication and cooling, so that the gear and the bearing are easily damaged and failed by gluing, overheating, transitional wear and the like.

SUMMERY OF THE UTILITY MODEL

The utility model belongs to a compact transmission gear case, transmission gear case's the box outside is equipped with heat radiation structure, heat radiation structure including heat dissipation bottom plate, side heat dissipation muscle and bearing heat dissipation platform, the one end outside of box be equipped with the pump case, through install heat radiation structure additional in the outside of gear box, both can carry out the efficient conduction to the heat of box inside through outstanding outer arris, thereby carry out the heat exchange to the air through the heat radiation structure in the outside again with heat conduction to the outside of box and improve the radiating effect to heat radiation structure has still played the effect of strengthening box structural strength, prevents because outside pressure collision or inside fast-speed rotation produce irreversible influence to the box.

The box shape is vertical upper and lower both ends open-ended rectangle casing, and the upper portion of box is equipped with the drawing die of the inboard that makes progress, and the front and back two sides of box all are equipped with the bearing mounting hole, the outside of bearing mounting hole all be equipped with bearing heat dissipation platform, box below both sides all be equipped with the side heat dissipation muscle, the bottom of box is equipped with the heat dissipation bottom plate, through the bearing mounting hole and the bearing heat dissipation platform that the box outside set up, with the independent setting of bearing in the outside of box, both can make the bearing separate with the inside main part that generates heat of box, make the bearing can carry out independent heat transfer, can also strengthen the front and back intensity of box to it is further firm to make holistic box intensity.

The shape of heat dissipation bottom plate is the rectangular plate, and the bottom of heat dissipation bottom plate is fore-and-aft is equipped with a plurality of heat dissipation arriss, and the both sides of heat dissipation bottom plate are passed through the bolt and are linked to each other with the bottom of box, dispel the heat to the box inside from the bottom through the heat dissipation bottom plate, and the bottom sealing effect of box still is played to the bottom of heat dissipation bottom plate simultaneously.

The side heat dissipation muscle is the bar muscle, and the lower part in the box side is established to the horizontal equidistance of side heat dissipation muscle, and the vertical side heat dissipation muscle that is equipped with on the central line of horizontal side heat dissipation muscle dispels the heat to the side of box through the side heat dissipation muscle, thereby the outside of effectual improvement box and the area of air contact improve the radiating effect to can also consolidate the side of box.

Has the advantages that:

the utility model discloses an install heat radiation structure additional in the outside of gear box, both can carry out the efficient conduction to the inside heat of box through outstanding outer arris, carry out the heat exchange to the air through the heat radiation structure in the outside again with heat conduction to the outside of box thereby improve the radiating effect, and heat radiation structure has still played the effect of strengthening box structural strength, prevent to produce irreversible influence to the box because outside pressure collision or inside fast-speed rotation, bearing mounting hole and bearing heat dissipation platform through the box outside setting, with the independent setting of bearing in the outside of box, both can make the bearing separate with the inside main part that generates heat of box, make the bearing can carry out independent heat transfer, can also strengthen the front and back intensity of box, thereby make further firm of holistic box intensity, dispel the heat to the box inside from the bottom through the radiating bottom plate, the radiating bottom plate still plays the bottom sealing effect of box simultaneously, dispel the heat to the side of box through the side heat dissipation muscle, thereby the outside of effectual improvement radiating effect is improved with the area of air contact, and can also carry out the reinforcement to the side of box.
