Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly, it is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As Figure 1-Figure 5：A kind of heat dissipation gear being conveniently replaceable, including gear 1, axis mounting bracket 2, the gear teeth 3 are cold
But sink 6, water injection hole 5, heat dissipation channel 7, microporous layers 4, T-shaped keyway 10, elastic element 11 and buffer board 12, the axis mounting bracket
2 include axle sleeve 13 and mounting blocks 15, and axis hole 14 is equipped in the axle sleeve 13, set that there are two the T-shaped keys of opposition on the axis hole 14
Slot 10, the T-shaped keyway 10 is interior to be connected with buffer board 12 by elastic element 11.The outside of the axle sleeve 13 is uniformly provided with several
Mounting blocks 15 are provided with installation cavity 16 in the mounting blocks 15, and screw 17 is equipped in the installation cavity 16 by mounting blocks 15 and tooth
The inside of wheel body 1 is connected.The bosh 6 shape and inside the gear 1 in a ring, the bosh 6 with
Water injection hole 5 connects, and the water injection hole is four, and is distributed in around the center of gear in 90 ° on gear face, the note
Water hole 5 is equipped with sealing cover 9.1 periphery of gear is equipped with several gear teeth 3, and heat dissipation channel 7 is equipped in the gear teeth 3,
While heat dissipation channel 7 is along its length in wavy, the heat dissipation channel 7 and 6 through connection of bosh, the bosh
6 and heat dissipation channel 7 in be equipped with separation layer 8, the separation layer 8 for heat dissipation silicon rubber, can effectively prevent coolant by gear sheet
Body 1 corrodes, and ensures gear long service life.The gear face of 6 side of bosh is equipped with microporous layers 4, described micro-
The setting of aperture layer 4 can ensure that bosh is communicated with the outside, and play the effect actually to cool down.
Axis mounting bracket 2 can be individually replaced when gear shaft holes 16 are worn, can be individually replaced when the gear teeth 3 are damaged
Gear 1, replacement process is identical, is back-outed from installation cavity 18 screw 19 using spanner, installs gear 1 and axis
Replacement can be realized in the separation of frame 2, need not carry out integral replacing, with strong points, replacement cost is small, while can be according to different
Occasion carries out dismounting restructuring to gear, meets the different ratio of 3 quantity of size and the gear teeth of gear shaft holes 16, it is various to meet enterprise
The production requirement of change.In the gear operation course of work, the region of engagement temperature between two gears is high.7 surface of heat dissipation channel is along length
Direction is in wavy, improves the intensity and resistance capacity to deformation of heat dissipation channel 7, when heat dissipation channel 7 is subject to slight external force, no
It can deform, improve the bulk life time of gear；The heat dissipation area of heat dissipation channel 7 is improved simultaneously, improves heat-sinking capability.
Four water injection holes 5 cause the replacement efficiency of coolant faster.When gear is mounted on an axle, the key on axis is pasted with buffer board 12
