Abstract
The utility model discloses an over twisting protection structure for a vertical transmission device. The over twisting protection structure comprises a tertiary reducer, a speed reduce support, and a main shaft from the top to the bottom, wherein an upper coupler , a lower coupler, a bearing cap, a single-row radial ball bearing, a bearing seat, an oil cup, and a single-row ball thrust bearing are arranged in the speed reduce support from the top to the bottom; the upper coupler and the lower coupler are connected with each other through a safety pin which penetrates from the top to the bottom. The over twisting protection structure has the benefits that the safety pin structure in transition fit is adopted, the safety pin is cut off once overloading occurs, and the upper coupler and the lower coupler are detached from each other, so that the equipment is prevented from being damaged without requiring any electrical control devices; the over twisting protection structure is reasonable in structure and stable in performance, and is safe and effective.
Description
Technical field
The utility model relates to a kind of mistake and turns round protection structure, and more specifically, it relates to a kind of vertical driving device and crosses and turn round protection structure.
Background technology
Sewage treatment plant builds more and more at present, and the concentration basin of each sewage treatment plant, all needs to use lifting center drive mud-scraper.Rare when dense during due to sludge concentration, the strength and stiffness of mud scraper are difficult to correct control, so it is blocked up to run into mud, mud scraper is overload operation usually, even destroyed.
Existing for lifting center drive mud-scraper torque overload protection new technique: torque value control measurement device, adopt Programmable Logic Controller and torque sensor, realize in theory Automatic Control.But sewage disposal plant is all outdoor installing and using, especially this main equipment of inconocenter transmission mud scraper, is all mounted in outdoor, the sun that drenches with rain shines, applying working condition is very poor, and torque sensor is difficult to correct reading, so that the accuracy of Automatic Control has is to be tested.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, stable performance, and vertical driving device is crossed and is turned round protection structure safely and effectively.
This vertical driving device is crossed and is turned round protection structure, comprises from top to bottom: triple reduction gear, reductor bearing and main shaft; In described reductor bearing, be provided with upper coupling, lower coupler, bearing cap, single-row radial ball bearing, supporting base, lubricating cup and single-row thrust ball bearing from top to bottom; Described upper coupling is connected by the safety pin running through up and down with lower coupler.
As preferably: described main shaft is connected with transmission output by lateral pin.
As preferably: described bearing cap and supporting base are provided with tank filler sleeve.
As preferably: the safety pin that described upper coupling is connected with lower coupler is uniform several.
The beneficial effects of the utility model are: adopt the safety pin structure of a set of interference fits, once load overload, safety pin is just cut off, and upper and lower disconnect coupling, avoids equipment destroyed.Without any electric control gear, rational in infrastructure, stable performance, safe and effective.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Reference numeral: triple reduction gear 1, safety pin 2, lower coupler 3, reductor bearing 4, single-row radial ball bearing 5, supporting base 6, main shaft 7, lateral pin 8, upper coupling 9, bolt 10, bearing cap 11, lubricating cup 12, single-row thrust ball bearing 13.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
This vertical driving device is crossed and is turned round protection structure, comprises from top to bottom: triple reduction gear 1, reductor bearing 4 and main shaft 7; In described reductor bearing 4, be provided with upper coupling 9, lower coupler 3, bearing cap 11, single-row radial ball bearing 5, supporting base 6, lubricating cup 12 and single-row thrust ball bearing 13 from top to bottom; Described upper coupling 9 is connected by the safety pin 2 running through up and down with lower coupler 3.Described main shaft 7 is connected with transmission output by lateral pin 8.Described bearing cap 11 and supporting base 6 are provided with tank filler sleeve.Safety pin that described upper coupling 9 is connected with lower coupler 32 is uniform several.
Before design, need according to maximum load allowable correct computationally secure pin smallest cross-sectional.Ensure that this complete equipment normally moves, and needs reasonable disposition rolling bearing.In order better to bear axial load, device adopts single-row thrust ball bearing 13, is arranged on supporting base 6; In order to bear radial load, device adopts single-row radial ball bearing 5, is arranged on supporting base 6.System, for better operation, needs lubricated and sealing, adopts the oil gun of simple possible to refuel, on bearing cap 11, supporting base 6, and the tank filler sleeve of design M10, convenient oiling.Adopt the sealing means that felt is installed on dovetail groove simultaneously, be unlikely to outflow of lubrication oil, also do not allow rainwater flow into rolling bearing, guarantee equipment normally moves.
