Abstract
The invention relates to a driving chain sprocket used for a rotary grating. The driving chain sprocket comprises an inner pipe body and an outer circular ring body. The excircle of the inner pipe body and the inner circle of the outer circular ring body are welded into a whole, and a tooth profile is processed on the excircle of the outer circular ring body. According to the driving chain sprocket used for the rotary grating provided by the invention, while the strength and rigidity requirements are met, the production cycle is shortened, the material cost is reduced, the material utilization rate is increased, and the weight of the driving chain sprocket is reduced.
Description
Technical field
The present invention relates to a kind of sprocket wheel, especially a kind of rotary type grid driving chain sprocket.
Background technique
At present; rotary type grid predominant use is solid-liquid screening; be applicable to municipal wastewater treatment plant technique for pretreating; water inlet as municipal wastewater treatment plant and residential quarters sewage treatment facility and town channel; also can carry out foreign material with power plant cooling water inlet for waterworks and separate the protection water pump vane; alleviate the processing load of subsequent handling, plant width is generally 1 meter to 6 meters, is a kind of domestic advanced person's solid-liquid sieving device.After the torque force that the driving chain sprocket of rotary type grid passes in the system of being activated, drive the strength member of the tooth harrow rotation motion on tooth harrow chain and chain.And the general preparation process of driving chain sprocket is first to use die casting, machining forms again, its shortcoming is a mold a kind of driving chain sprocket specification of can only casting, when needs amplify or reduce relative dimensions, just must again open a mold, could utilize cast steel to water and outpour the driving chain sprocket met the demands, exist the manufacture cycle long, the shortcomings such as waste of material is large, and own wt is large.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of easy to process, stock utilization is high, lightweight rotary type grid driving chain sprocket.
According to technological scheme provided by the invention, described rotary type grid driving chain sprocket, it comprises interior tube body and cylindrical ring body, the inner circle of the cylindrical of interior tube body and cylindrical ring body is welded, is processed with profile of tooth on toric cylindrical outside.
Evenly offer outside lightening hole on cirque body.
When the present invention has met intensity and stiffness requirement, shortened the manufacture cycle, saved cost of material, improved stock utilization, and alleviated own wt.
The accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Fig. 2 is left view of the present invention.
Fig. 3 is the plan view of prior art.
Fig. 4 is the left view of prior art.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This rotary type grid driving chain sprocket, it comprises interior tube body 1 and cylindrical ring body 2, the inner circle of the cylindrical of interior tube body 1 and cylindrical ring body 2 is welded, is processed with profile of tooth 3 on the cylindrical of cirque body 2 outside.
Evenly offer lightening hole 4 on cirque body 2 outside.
The present invention, when making, first cuts out the cylindrical of a cylindrical ring body 2 as driving chain sprocket with steel plate, separately uses one section round steel as interior tube body 1, then cylindrical ring body 2 and interior tube body 1 welding are made to blank, finally is machined to required size.
Rotary type grid of the present invention has shortened the process-cycle with driving chain sprocket, can meet the requirement of strength and stiffness, and processing cost of the present invention is low, applied widely.
Claims (2)
