Abstract
The utility model relates to a circumferential location roller gear, including the wheel body and locating a plurality of driving cogs on the wheel body outer peripheral face, the axial middle part of wheel body is equipped with the mounting hole, and the circumference equipartition has a plurality of keyways on the inner wall of mounting hole, and equal fixed mounting has the shell fragment on each inner wall of keyway, and a plurality of shell fragments are evenly arranged on the inner wall of keyway. The utility model discloses a circumferential location roller gear, through the bow -shaped shell fragment of fixed mounting on each face of keyway, after being connected between the transmission shaft passes through key piece and wheel body, bow -shaped shell fragment is because the elastic reaction is inconsistent with the key piece all the time, when all going out the freshly ground damage on each face of bow -shaped shell fragment contact on key piece and keyway, the key piece receives bow spring's conflict, make and still mobilizable clearance can not appear between impaired key piece and the keyway, thereby the compactedness be connected has been guaranteed between wheel body and the axis of rotation, moreover, the steam generator is simple in structure, machining is convenient.
Description
Technical field
The utility model is related to roller gear technical field, especially relates to a kind of circumferentially positioned roller gear.
Background technology
Roller gear is the gear that a kind of reference surface is cylinder, and its purposes is wider, can be used for aviation in mechanical field
Machinery, mining machinery, can be used for wrist-watch, in electric fan in daily life.Traditional roller gear is by wheel body, located at wheel body outer peripheral face
Upper some driving cog compositions, the middle part of wheel body axial direction is provided with installing hole, and traditional installation in the hole is typically provided with keyway, by key block
Implement to be connected with power transmission shaft.However, after a protracted use, key block is in keyway can be worn and torn accordingly, make
Gap is produced, roller gear operationally then can wave between key block and keyway, thus cannot stable and ex-ternal transmission
Engagement implemented by gear, has influence on transmission effect.The method of traditional this problem of solution is to open up blind hole in the bottom of keyway,
Spring is installed to prop up key block in blind hole, realizes the compactedness being connected between wheel body and rotary shaft, but open in the bottom of keyway
If blind hole reduces the overall rigidity of roller gear, shorten the service life of roller gear；The abrasion of key block is to occur in key
On each face that block is contacted with keyway, only flexible member is set in the bottom of keyway, the stability of key block is not high.
Utility model content
The technical problems to be solved in the utility model is：In order to solve because key block abrasion make between key block and keyway produce between
Gap, roller gear operationally waves, thus cannot be stable engage with the enforcement of ex-ternal transmission gear, has influence on transmission effect
Really, the method for traditional this problem of solution is to open up blind hole in the bottom of keyway, installs spring to prop up key block in blind hole,
Realize the compactedness being connected between wheel body and rotary shaft, but open up blind hole in the bottom of keyway and reduce roller gear entirety
Rigidity, has shortened the service life of roller gear；The abrasion of key block is to occur, on each face that key block is contacted with keyway, only to exist
The bottom setting flexible member of keyway, the not high problem of stability of key block, a kind of circumferentially positioned roller gear is provided.
The utility model solves its technical problem and be employed technical scheme comprise that：A kind of circumferentially positioned roller gear, including
Wheel body and some driving cogs on wheel body outer peripheral face, the middle part of described wheel body axial direction is provided with installing hole, described installing hole
Some keyways are evenly distributed on inwall, each inwall of described keyway are all installed with shell fragment, some shell fragments are in keyway
Inwall on uniformly arrange.
Further, described shell fragment is bow-shaped shrapnel.
For the ease of being welded and fixed shell fragment, the two ends of described bow-shaped shrapnel are equipped with welding location hole.
The beneficial effects of the utility model are:Circumferentially positioned roller gear of the present utility model, by keyway each
On face fixedly mount bow-shaped shrapnel, when power transmission shaft pass through key block and wheel body between be connected after, bow-shaped shrapnel due to elastic reaction beginning
Inconsistent with key block eventually, when all abrasion on each face that key block is contacted with bow-shaped shrapnel on keyway, key block is subject to arch
The conflict of spring, making between impaired key block and keyway is not in still mobilizable gap, thus ensure that wheel body and turning
The compactedness connecting between moving axis, structure is simple, easy to process.
Brief description
With reference to the accompanying drawings and examples the utility model is further illustrated.
Fig. 1 is schematic three dimensional views of the present utility model；
Fig. 2 is the enlarged drawing at A in the utility model Fig. 1；
Fig. 3 is front view of the present utility model；
Fig. 4 is the schematic three dimensional views of bow-shaped shrapnel in the utility model.
In figure：1. wheel body, 2. driving cog, 3. installing hole, 4. keyway, 5. bow-shaped shrapnel, 6. welds location hole.
Specific embodiment
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with the utility model.
A kind of circumferentially positioned roller gear as shown in figures 1 and 3, if including wheel body 1 with wheel body 1 outer peripheral face
Dry driving cog 2, the middle part of described wheel body 1 axial direction is provided with installing hole 3, and the inwall of described installing hole 3 is evenly distributed in some keys
Groove 4, each inwall of described keyway 4 is all welded and fixed and is provided with bow-shaped shrapnel 5 as shown in Figure 4, and some bow-shaped shrapnels 5 exist
Uniformly arrange on the inwall of keyway 4, as shown in Figure 2.For the ease of being welded and fixed shell fragment, the two ends of described bow-shaped shrapnel 5 are all provided with
There is welding location hole 6.
By bow-shaped shrapnel 5 is fixedly mounted on each face of keyway 4, when power transmission shaft passes through to connect between key block and wheel body 1
After connecing, bow-shaped shrapnel 5 is inconsistent with key block all the time due to elastic reaction, contact with bow-shaped shrapnel 5 on keyway 4 when key block each
When all abrasion on face, key block is conflicted by semielliptic spring, and making between impaired key block and keyway 4 is not in still can
The gap of activity, thus ensure that the compactedness being connected between wheel body 1 and rotary shaft, structure is simple, easy to process.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited on specification with new technical scope it is necessary to determine its technology according to right
Property scope.
