Description
Technical field
This utility model relates to a kind of sprocket wheel, is specifically designed a kind of sprocket wheel carrying spoil disposal function.
Background technology
Sprocket wheel is the wheel of band sprocket, for engaging with transmitting movement with chain, is widely used in vehicle, chemical industry, weaving
The machine driving etc. of the industries such as machinery, food processing, instrument, oil.Sprocket tooth form must assure that chain is energy-conservation the most freely
Ground enters and exits engagement, the impact of chain link when minimizing is engaged as far as possible and contact stress, and to be prone to processing.
Sprocket wheel can accumulate the foreign material such as dust, silt, increasing friction force at chain between cog after a long time use, hinders sprocket wheel
Steadily entrance the most freely and exit engagement, accelerates the loss of sprocket wheel, shortens service life.
Utility model content
For defect of the prior art, this utility model provides a kind of from spoil disposal sprocket wheel, during engagement can automatic mud removing,
Increase the service life.
The one that this utility model provides is from spoil disposal sprocket wheel, including: body be arranged on described the multiple of body cylindrical and take turns
Tooth, is provided with the mud drainage slot running through face, body rear and front end, and described mud drainage slot bottom the roller seating space between two gear teeth of arbitrary neighborhood
Cross-sectional area be gradually increased along the most unidirectional of described body.
Further, the cross-sectional area of described mud drainage slot along described body axial from centre forwards, backwards two ends two-way gradually
Increase.
Further, described mud drainage slot is arc transition with the connecting portion of described roller seating space.
Further, two interior angles bottom described mud drainage slot are arc transition.
Further, the end face of described body is provided with and described body concentric cannelure, and described cannelure is with described
The bottom connection of mud drainage slot.
Further, before and after described body, two end faces are both provided with described cannelure.
Further, the axis hole of described body is provided with the pin-and-hole of indent.
Further, described body is provided with multiple fixing hole.
Further, described body is provided with multiple lightening hole.
Further, the described Facing material from spoil disposal sprocket wheel is trivalent chromium coloured silk zinc.
The mud drainage slot being provided with variable cross-section from spoil disposal sprocket wheel bottom roller seating space of the present utility model, area of section is single vertically
To being gradually increased.During work, owing to area of section is different, the pressure that silt is born in each cross section is different from, and with cross section
Increasing, pressure reduces, and spoil disposal resistance is also gradually reduced, and effectively prevents cross section phase simultaneously as silting or run into bigger
Stone, blocks mud drainage slot, affects sludge discharge effects, so variable cross-section mud drainage slot spoil disposal of the present utility model is more smooth and easy, it is to avoid mud
The husky alluvial at root portion, thus effectively extend the service life of sprocket wheel.

Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of technical solutions of the utility model is described in detail.Following example are only
For the technical solution of the utility model is clearly described, therefore it is only used as example, and this practicality can not be limited with this
Novel protection domain.
It should be noted that except as otherwise noted, technical term used in this application or scientific terminology should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
Referring to figs. 1 through Fig. 3, embodiment one provide from spoil disposal sprocket wheel, including: body 100 be arranged on described body 100
Multiple gear teeth 200 of cylindrical, are provided with bottom the roller seating space between two gear teeth 200 of arbitrary neighborhood and run through face, body 100 rear and front end
Mud drainage slot 201, and the cross-sectional area of described mud drainage slot 201 along described body 100 axial, from centre, two ends are gradually forwards, backwards
Increase.Being additionally provided with an axis hole 101 on body 100, axis hole 101 is provided with pin-and-hole 104.Four fixing holes it are additionally provided with on body 100
102, and four lightening holes 103.
The mud drainage slot 201 being provided with variable cross-section from spoil disposal sprocket wheel bottom roller seating space of the present embodiment, area of section is from centre
It is gradually increased to two ends.During work, owing to area of section is different, the pressure that silt is born in each cross section is different from, and with
Cross section increases, and pressure reduces, and spoil disposal resistance is also gradually reduced, and effectively prevents cross section phase simultaneously as silting or run into relatively
Big stone, blocks mud drainage slot 201, affects sludge discharge effects, so variable cross-section mud drainage slot 201 spoil disposal of the present utility model is more suitable
Freely, it is to avoid silt is in the alluvial of root portion, thus effectively extends the service life of sprocket wheel.
With reference to Fig. 4, in embodiment two, the cross-sectional area of described mud drainage slot 201 the most in the past arriving along described body 100
After be gradually increased, when area of section is gradually increased the most from front to back, owing to silt can flow to pressure from the big direction of pressure
The direction that power is little, also can effectively dredge spoil disposal direction, according to assembling mode, selects the direction of spoil disposal, makes silt mostly arrange to not
Affect the direction of operating mechanism, prevent spoil disposal from other mechanisms being caused damage, thus the service life of extending mechanism.
In order to improve sludge discharge effects, it is to avoid dead angle accumulation silt, two interior angles of described mud drainage slot 201, and with described
The connecting portion of roller seating space is arc transition.
The Facing material from spoil disposal sprocket wheel of the present embodiment is environmental protection trivalent chromium coloured silk zinc, meets outlet developed country quality inspection mark
Standard, and surface passivation ability is strong, being difficult to get rusty is difficult to scratch.
In order to improve sludge discharge effects further, described mud drainage slot 201 is the most a plurality of, and is also disposed with on the gear teeth 200
Mud drainage slot 201.Multiple mud drainage slots 201 also can be crisscross arranged, and interpenetrates, and prevents the wherein mud drainage slot 201 from blocking, impact row
Mud effect.
With reference to Fig. 5 to Fig. 7, in embodiment three, the end face of described body 100 is provided with concentric with described body 100
Cannelure 202, described cannelure 202 connects with the bottom of described mud drainage slot 201.When the silt in described mud drainage slot 201 flows
During to cannelure 202, fall from cannelure 202 under the influence of gravity, accelerate spoil disposal, thus improve the spoil disposal of mud drainage slot 201
