Abstract
The utility model relates to a speed reducer used in the hoisting of a hoist. The speed reducer comprises a casing and is characterized in that a mounting cover plate is fastened on the side surface of the casing; a motor output shaft is mounted at the lower part of the casing in a penetrating manner; a pinion of the motor output shaft is mounted on the motor output shaft in a penetrating manner; a secondary pinion is mounted at the middle part of the casing in a penetrating manner; external teeth are formed at one end of the shaft of the secondary pinion, and a primary gearwheel is mounted at the other end of the shaft in a penetrating manner; the primary gearwheel meshes with the pinion of the motor output shaft; an output shaft of the speed reducer is mounted at the lower part of the casing in a penetrating manner; a secondary transmission gearwheel meshing with external teeth is mounted on the output shaft of the speed reducer in a penetrating manner; and a pinion meshing with the annular gear of a winding drum is processed at the part of the output shaft of the speed reducer positioned outside the casing. The utility model can reduce the speed reducing stage of the speed reducer to be two, enable the motor and the winding drum not to be mounted on the same axis, and enable the axial length of an electric hoist to be greatly reduced, thereby reducing blind areas in the operation and transportation process and increasing effective operation space. Besides, the mounting cover plate can be opened aside, which can avoid oil leakage and penetration and enables the speed reducer to be suitable for places with high requirement for sanitation.
Description
Technical field
The utility model belongs to the hoisting crane technical field, particularly relates to a kind of cucurbit retarder that hoists.
Background technology
At present, the retarder that hoists in the known technology is in the same place the coaxial connection of electrical motor and reel, and this structure is compact inadequately; Especially its axial length is longer, easily forms bigger work blind area in the course of the work, and working environment is had relatively high expectations, and is not suitable for using in less operation interval the operation easier when also having increased simultaneously work; Existing retarder shell is many to be made of casing and case lid two parts, because gapped between casing and the case lid, sealing effectiveness is relatively poor, causes this structure that oil leakage phenomenon in use takes place easily; Existing reductor afterbody reducing gear external diameter is bigger, causes the cabinet size of reductor bigger, and the overall volume of the lifting mechanism of formation is huge, and overall weight is heavier, must select heavy-duty motor for use, and energy resource consumption is bigger.
Summary of the invention
The utility model provides the cucurbit of a kind of compact conformation, the good sealing effect retarder that hoists for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
The cucurbit retarder that hoists, comprise housing, it is characterized in that: the bottom installs motor output shaft in the housing, be installed with the motor output shaft miniature gears on the motor output shaft, the side of housing is fastened with the installation cover plate by fastener, and the housing middle part is coated with second stage pinion shaft, pinion shaft one end in the second stage is processed with external tooth, the other end is coated with first order big gear wheel, first order big gear wheel and motor output shaft pinion, and housing top is coated with the reducer output shaft that is parallel to each other with motor output shaft; Be coated with transmission big gear wheel in the second stage on the reducer output shaft, transmission big gear wheel in the second stage is meshed with external tooth on the pinion shaft of the second stage, reducer output shaft be positioned at the internally toothed annulus pinion in mesh that is processed with on the outer part of housing with reel.
Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, can make the retarder retarding stage be reduced to two-stage.This retarder can make electrical motor and reel not be installed on the same axis, and the electric block axial length is shortened greatly, thereby the blind area in the work transportation is reduced, and effective working space increases.Open because the cover plate side is installed, thereby avoided leakage of oil, oil impregnate phenomenon, be applicable to the place higher the hygienic conditions conditional request.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is that the K of Fig. 3 is to view.
Among the figure: 1, housing; 2, first order big gear wheel; 3, second stage pinion shaft; 3-1, external tooth; 4, reducer output shaft; 5, second stage big gear wheel; 6, miniature gears; 7, seal ring; 8, cover plate is installed; 9, motor output shaft; 10, motor output shaft miniature gears.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 4, a kind of cucurbit retarder that hoists, comprise housing 1, the bottom is installed with motor output shaft 9 in the housing 1, is coated with motor output shaft miniature gears 10 on the motor output shaft, and the side of housing 1 is fastened with by fastener cover plate 8 is installed, housing 1 middle part is coated with second stage pinion shaft 3, pinion shaft one end in the second stage is processed with external tooth 3-1, and the other end is installed with first order big gear wheel 2, first order big gear wheel 2 and 10 engagements of motor output shaft miniature gears.Housing 1 top is coated with the reducer output shaft 4 that is parallel to each other with motor output shaft 9, be coated with second stage transmission big gear wheel 5 on the reducer output shaft 4, second stage transmission big gear wheel 5 is meshed with external tooth 3-1 on the pinion shaft of the second stage, reducer output shaft 4 be positioned at the internally toothed annulus pinion in mesh 6 that is processed with on the outer part of housing 1 with reel.
Because motor output shaft 9 is meshed with the first order big gear wheel 2 of retarder, and the reducer output shaft end is equipped with a miniature gears 6, this miniature gears is meshed with the coaxial internally toothed annulus that is packed on the reel.This kind project organization also can make the retarder retarding stage be reduced to two-stage.This retarder can make electrical motor and reel not be installed on the same axis, and then the electric block axial length is shortened greatly, reduces the blind area in the work transportation, increases effective working space.In addition, the cover plate side is installed opens, can avoid leakage of oil, oil impregnate phenomenon, therefore be specially adapted to the place higher the hygienic conditions conditional request.
