Abstract
The utility model relates to an assembled impeller structure for a single screw compressor, which is mainly composed of a main shaft, detachable vanes, an impeller body, a check ring and a press plate, wherein, the check ring and the press plate respectively press down the upper and the lower surfaces of vane roots. A working face of the vanes can be a single material structure or a composite material structure in which a base material adheres with a layer of working material. The detachable vanes can be singly processed and assembled, so that the mesh gap of the product compressor is reduced to approximate zero. Thus, the utility model with the advantages of application to batch production and convenient processing, replacement and maintenance for the vanes can reduce operation leakage, raise volumetric efficiency, raise manufacturing quality and reduce product cost.
Description
The utility model relates to a kind of blade wheel structure of gas compressor.
At present, proceed to by traditional reciprocating structure in the trend of advanced rotary structure at gas compressor, single screw compressor is to come out to have the rotary compressor of new generation of premium properties soon, and its working principle is actually the once ingenious application to the double enveloping worm transmission.But the impeller of present single screw compressor is the integrated type blade wheel structure.Theory analysis shows, by existing integrated type blade wheel structure, owing to be subjected to the restriction of flank interference, realize mounting or dismounting, must leave certain interval in the engaging tooth shape both sides, and this just causes the decline of volumetric efficiency in the work.In addition, the integrated type impeller also brings the difficulty of processing and maintenance.
The purpose of this utility model is: a kind of assembly type blade wheel structure of single screw compressor is provided, it can be assembled in addition in the joggleword district, reduce gap and leakage, the assembling maintenance is easy, simplified manufacturing process, and improve workmanship.
The purpose of this utility model is achieved in that wheel blade is dismountable wheel blade, also has back-up ring and pressing plate in a kind of single screw compressor assembly type blade wheel structure of mainly being made up of main shaft, wheel blade and wheel body.The top seam of wheel blade blade root inserts in the endoporus of ring washer, fastens mutually.Pressing plate be contained in wheel blade and wheel body assembled part blade root below, contact with the lower surface of blade root.On the inclined-plane that the contact segment of pressing plate and blade root respectively has a same slope, pressing mutually.
Because adopt technique scheme, wheel blade is dismountable, can process separately and assemble.After installing, the heart changes the meshing zone under the situation over to and just no longer has difficulties at work.Correctly machining the worm screw working flank, reaching the theoretical profile of tooth of hindley worm, and having under the sufficiently high helix precision conditions, the back lash of product compressor is narrowed down near zero, making to leak in the work to reduce, volumetric efficiency improves greatly.Owing to have back-up ring and pressing plate, push down the upper and lower surface of wheel blade blade root respectively, not only play positioning action, also can make the blade installation of assembly type impeller firm, running is reliable.Simultaneously,, compare with the integrated type blade wheel structure owing to be detachable wheel blade, easy to process, can improve workmanship, change and keep in repair easily, be suitable for producing in batches, reduce product cost.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the erection drawing of the utility model assembly type blade wheel structure
Fig. 2 is the plan view of Fig. 1
Among the figure, 1. main shaft 2. back-up rings 3. wheel blades 4. pressing plates
The utility model assembly type blade wheel structure illustrated in figures 1 and 2 is made up of main shaft 1, dismountable wheel blade 3 and wheel body, also has back-up ring 2 and pressing plate 4.The top seam of wheel blade 3 blade roots is inserted in the endoporus of back-up ring 2, fastens mutually.Pressing plate 4 is contained in below the blade root, contacts with the lower surface of blade root, and on the inclined-plane that contact segment respectively has a same slope, pressing mutually.Basic meshing parameter in the present embodiment is: screw head is counted Z1=6, impeller tooth number Z 2=11, distance of shaft centers A=120mm, screw rod outside diameter d 1=150mm, impeller tip diameter d2=150mm, impeller facewidth b=20mm.
The working surface of wheel blade 3 can be the homogenous material structure, also can be the composite structure that is adhered to one deck work materials by body material.When adopting composite teeth flooring structure, also can suitably reduce requirement, improve the mechanical efficiency of engagement machining accuracy.In the present embodiment, wheel blade 3 end faces are pasted one deck ptfe sheet, and thickness is 4mm, in order to improve the engages and seals performance.The material of thin slice and thickness can appropriate changes, for example also can consider to adopt fluorine rubber, polyurethane etc.Additional two tingles of hiding are the deficiencies for additional bonding force, enough also shouldn't tingle as bonding force.Wheel blade also can be made by homogenous material, as adopting duralumin, hard alumin ium alloy, engineering plastics etc.
The assembly process of present embodiment assembly type blade wheel structure is as follows: main shaft 1 can be encased on the working position in advance, and wheel blade 3 rotates into the joggleword district again and just becomes and have no difficulty after non-joggleword district assembles one by one.Back-up ring 2 has been sleeved on one heart earlier the shoulder of main shaft 1 during assembling, two parallel end faces of back-up ring 2 are all vertical with the axle center.Wheel blade 3 relies on blade root to be bumped in the straight trough of main shaft 1, up to abutting against on the main shaft cylindrical.And on the main shaft 1 11 uniform straight troughs be designed to groove be intended to be convenient to processing.To push away on the wheel blade 3 then, make the top seam of its blade root enter back-up ring 2 endoporus and be adjacent to, add spring washer with screw again pressing plate 4 is installed on the working position with its end face.The inclined-plane of pressing plate 4 is pressed on the inclined-plane of wheel blade 3 blade root bottoms, and wheel blade 3 is remained on the correct working position.
Claims (2)
