Abstract
The utility model relates to an improvement of novel impeller nut, which comprises an impeller nut body threadedly connected with end part of a transmission shaft; the center of the lower part of the impeller nut body is upwardly provided with a thread blind hole having fit with the transmission shaft correspondingly; the center of the upper part of the nut body is downwardly provided with a fixed hole penetrating to the blind hole; the aperture of the blind hole is greater than that of the fixed hole; the center of the end surface of the transmission shaft is provided with a mounting hole corresponding to the fixed hole; the end part of the transmission shaft is sleeved in the blind hole of the nut body and is butted therewith by screw threads; and a screw is fixed in the mounting hole on the transmission shaft after passing through the fixed hole of the nut body. The improvement of novel impeller nut has the advantages that: structure of the impeller nut is optimized and mounting difficulty of the impeller nut is lowered; meanwhile, weight of the impeller nut is reduced, processing technology is simplified, operation is simpler, more convenient and faster, and cost is saved.
Description
Technical field
The utility model relates to impeller nut, particularly a kind of improvement of novel impeller nut.
Background technique
Among Fig. 1, conventional water pump because the space is limited, tends to collide with the blade of impeller or have only very little distance when the mounted impeller nut when mounted, causes blade that wearing and tearing are arranged.And in limited space, nut does not just have the activity space of spanner, and soundness is bad, influences the hydraulic performance of impeller greatly.So, be badly in need of a kind of novel impeller nut and the mounting structure of transmission shaft.
Summary of the invention
The purpose of the utility model is to solve the aforementioned problems in the prior, and a kind of improvement of novel impeller nut is provided.
The utility model relates to the improvement of novel impeller nut; Comprise: the impeller nut body that is connected with the transmission shaft end thread; It is characterized in that: the lower central place of said impeller nut body upwards is provided with the tapped blind hole with the transmission shaft corresponding matching; The central upper portion place of nut body is to having the fixed hole that is through to blind hole, and the aperture of blind hole is provided with the mounting hole corresponding with fixed hole greater than the aperture of fixed hole in the end face center of transmission shaft; The end of transmission shaft is sheathed on the interior and screw thread butt joint of blind hole of nut body, and the fixed hole that a screw passes nut body is fixed in the mounting hole on the transmission shaft.
Being centered close on the straight line of said blind hole, fixed hole, mounting hole.
The utility model has the advantages that: optimized the structure of impeller nut, reduced the installation difficulty of impeller nut, alleviated the weight of impeller nut simultaneously, simplified processing technology, made operation more simple and convenient quick, practiced thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the use schematic representation of the utility model.
Fig. 3 is the structural representation of impeller nut in the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Among the figure; The improvement of novel impeller nut; Comprise: the impeller nut body 3 with transmission shaft 1 end thread is connected is characterized in that: the lower central place of said impeller nut body upwards is provided with the tapped blind hole 31 with the transmission shaft corresponding matching, and the central upper portion place of nut body is to having the fixed hole 32 that is through to blind hole; The aperture of blind hole is provided with the mounting hole corresponding with fixed hole greater than the aperture of fixed hole in the end face center of transmission shaft; The end of transmission shaft is sheathed on the interior and screw thread butt joint of blind hole of nut body, and the fixed hole that one 4 screws pass nut body is fixed in the mounting hole on the transmission shaft.
Being centered close on the straight line of said blind hole, fixed hole, mounting hole.
This creation has following characteristics: the first, and convenient during the mounted impeller nut, the space is bigger, can not contact with impeller blade, the impeller hydraulic performance is impacted because of the wearing and tearing impeller blade with regard to bad meeting like this; The second, need not tighten impeller nut with spanner, just connect with screw at the impeller nut tail end, it is more simple and convenient to operate.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The utility model has the advantages that: optimized the structure of impeller nut, reduced the installation difficulty of impeller nut, alleviated the weight of impeller nut simultaneously, simplified processing technology, made operation more simple and convenient quick, practiced thrift cost.
Claims (2)
