Abstract

The utility model discloses a kind of gear of replaceable teeth portion, comprise circular gear mass, wheel hub and the gear teeth, described gear mass is circumferentially evenly equipped with jack, the Topland of the gear teeth inserts from the jack on the inner headed face of gear mass and stretches out periphery, described jack external frame with to be plugged among it and consistent with the external frame of the gear tooth portions of its laminating, wheel hub mates with the inner circle of gear mass, is provided with flat key between the tooth bottom surface of described wheel hub and the gear teeth.Gear of the present utility model can be changed for the gear teeth of wearing and tearing, provides cost savings.

Description

A kind of gear of replaceable teeth portion
Technical field
The utility model relates to a kind of gear, is specifically related to a kind of gear of replaceable teeth portion.
Background technique
During gear transmission, the flank of tooth and the flank of tooth, can produce and roll between the flank of tooth and tooth root, this damage causes gear to lose accurate transmission, and need change whole gear and just can deal with problems, maintenance cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of gear of replaceable teeth portion.
For solving the problems of the technologies described above, the technical solution of the gear of the replaceable teeth portion of the utility model is:
Comprise circular gear mass, wheel hub and the gear teeth, described gear mass is circumferentially evenly equipped with jack, the Topland of the gear teeth inserts from the jack on the inner headed face of gear mass and stretches out periphery, described jack external frame with to be plugged among it and consistent with the external frame of the gear tooth portions of its laminating, wheel hub mates with the inner circle of gear mass, is provided with flat key between the tooth bottom surface of described wheel hub and the gear teeth.
The tooth root of the described gear teeth is extended with boss to both sides.
The inner headed face of described gear mass is provided with jump-ring slot with the matched position of the bi-side of wheel hub, and jump ring is located in jump-ring slot.
The technique effect that the utility model can reach is:
The gear teeth of gear of the present utility model are replaceable structure, gear teeth generation wearing and tearing cause cannot accurately transmission time, wheel hub can be extracted, to wearing and tearing the gear teeth change.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of gear of replaceable teeth portion, comprise circular gear mass 1, wheel hub 3 and the gear teeth 2, described gear mass 1 is circumferentially evenly equipped with jack 6, the Topland 5 of the gear teeth 2 inserts from the jack 6 on the inner headed face of gear mass 1 and stretches out periphery, described jack 6 external frame with to be plugged among it and consistent with the external frame of the gear tooth portions of its laminating, wheel hub 3 mates with the inner circle of gear mass 1, is provided with flat key 4 between described wheel hub 3 and the tooth bottom surface 7 of the gear teeth 2.
The tooth root of the described gear teeth 2 is extended with boss 9 to both sides.
The inner headed face of described gear mass 1 is provided with jump-ring slot 8 with the matched position of the bi-side of wheel hub 3.In jump-ring slot 8, be provided with jump ring, jump ring ensures that wheel hub 3 can not come off in gear operation vibrations process.
Installation method of the present utility model:
The Topland 5 of the gear teeth 2 passes jack 6 from inside to outside on gear mass 1, tooth root to the gear teeth 2 is embedded in jack 6, tooth bottom surface 7 matches with the inner headed face of gear mass 1, then on inner headed face, wheel hub 3 is put into, and the keyway on wheel hub 3 need match with the keyway on the gear teeth 2 tooth bottom surface 7, then inserts flat key 4 on keyway, finally, in jump-ring slot 8, put jump ring, screens is in the both sides of wheel hub 3.
