Abstract
The utility model relates to a transmission assembly applied in a driving device of an underwater pollution discharge pump, and the structure is characterized in that both ends of a transmission shaft fix pin elastomer couplings, and at the inner sides of the two pin elastomer couplings, two rolling bearing are fixed on the transmission shaft; an upper end is a fixed end bearing, and a lower end is a free end bearing; an inner ring of the upper rolling bearing is fixed on the transmission shaft through a collar, and an outer ring is tightly fixed to a top chuck position of a connecting frame by a bearing gland through a screw bolt; an inner ring of the lower end roller bearing is fixed on the transmission shaft through the collar, and an outer ring slides at a bottom chuck position of the connecting frame; the transmission assembly is flexibly connected with a pump assembly by the pin elastomer couplings, and the transmission assembly is flexibly connected with a motor by the pin elastomer couplings. When the utility model is used, multi-stage assemblies can be connected to use, and the utility model has quantitative compensation diaxon relativity shift and general vibration reduction and buffering performance. The utility model causes a pump to smoothly operate with no vibration and low noise, and the depth under liquid can be completely produced according to the requirements of users. The utility model has the advantages of convenient production and management, convenient machine work, and convenient assembly.
Description
Technical field
The utility model is the transmitting assemblies that is applied in the liquid following formula pollution discharge pump transmission device, particularly to the improvement of its structure.
Background technique
Existing liquid following formula pollution discharge pump, no matter how dark under the liquid, its transmission device all adopts the structural type of a transmission shaft, and is middle with sliding bearing support, transmission.Because the structure of its transmission shaft is very limited pump aspect the degree of depth under liquid; This structure is because the influence of the diameter of axle, limited the degree of depth under the liquid of pump.The degree of depth is dark more under the liquid, and the operation of pump is just unstable more, and not only noise is big, more is easy to generate resonance; Bring very big inconvenience also for simultaneously machining, assembling and production management, and increased the manufacture cost of product.More and more be subjected to today that people pay close attention in environmental problem, the occasion that liquid following formula pollution discharge pump uses is more and more, and demand is increasing, and it is imperative to solve above-mentioned defective.
Summary of the invention
This practical follow-on purpose provides a kind of can reducing cost, and can make again to manufacture conveniently, more can widen the transmitting assemblies of the liquid following formula pollution discharge pump transmission device of use occasion.The purpose of this utility model is achieved in that under the certain condition of the diameter of axle, axle is designed to stiff shaft, change the quantity of transmitting assemblies 3 along with the change of the degree of depth under the liquid, transmitting assemblies 3 is generally 1 meter 1 joint, and transmitting assemblies 3 comprises: transmission shaft 31, link press span 32, rolling bearing 33, elastic dowel pin shaft coupling 34, bearing gland 35, collar 36, bolt 37.Transmission shaft 31 is designed to stiff shaft, two fixing elastic dowel pin shaft couplings 34 of end of transmission shaft 31, and in two elastic dowel pin shaft couplings, 34 inboards, the longer the better under the situation of space permission to fix the spacing of two rolling bearing 33, two rolling bearings 33 on the transmission shaft 31; The rolling bearing of the upper end of transmitting assemblies 3 is the fixed end bearing, and rolling bearing 33 inner rings are fixed on the transmission shaft 31 by collar, the outer ring with bearing gland 35 by bolton at link press span 32 upper bearing bracket positions; The rolling bearing of the lower end of transmitting assemblies 3 is the free end bearing.Rolling bearing 33 inner rings are fixed on the transmission shaft 31 by collar, move about at link press span 32 step positions in the outer ring; Static seal seals with O-ring seals 6.
The utility model is applied in the liquid following formula pollution discharge pump transmission device, can connect use by multistage transmitting assemblies, transmitting assemblies 3 and pump assembly 4, transmitting assemblies 3 and motor 5, transmitting assemblies 3 and transmitting assemblies 34 flexible connections of 3 usefulness elastic dowel pin shaft couplings have quantitative compensation diaxon relativity shift and general vibration damping, shock-absorbing capacity.The utility model can make pump running steadily, and friction, noise are low, and the degree of depth fully can be according to user's requirement production under the liquid.Production management, machining, assembling are all very convenient, are suitable for producing in batches.
