Abstract
The invention discloses a speed reducer of a novel transmission structure. The speed reducer comprises a planetary driving frame, a carrying bearing, a box, an output shaft and an elastic buffering pad mounted inside the output shaft. Taking bearing capability and the transmission structure of the speed reducer into consideration, movement and power transmission can be realized better by utilizing the structure, the transmission structure is adjusted, radial size of a bearing (rotating member) can be increased as much as possible, and bearing capability of parts of the speed reducer is improved; the transmission structure is simplified, the number of the parts is reduced, processing techniques of the parts are simplified, and manufacturing cost is saved.
Description
Technical field
The invention belongs to the drive mechanism technology of speed reducer, be specifically related to a kind of new gear drive mechanism and bearing mounting structure.
Background technique
Along with the development of modern city and towns, concrete mixing and transporting car becomes the requisite a kind of haulage device that stirs of city-building as a kind of movable prefabricated concrete-agitating transport equipment.And concrete mixing and transporting car to drive one of critical component of tank body running be planetary speed reducer, the planetary reduction gear box body output terminal of traditional sense is made into support that indent aperture is less than Φ 200 for crucial load bearing element bearing is installed.Selecting of bearing is subject to size restrictions, can only select undersized bearing, and its bearing capacity is lower, cannot select and can meet the bearing that generous amount (being greater than 12 sides) concrete mixing and transporting car uses, and limited the development of concrete mixing and transporting car.Traditional housing structure manufacturing process complexity, manufacturing expense is comparatively expensive.And the planetary speed reducer of traditional sense, the motion between its planetary drive frame and output shaft and power need to transmit by other part, and transmission efficiency is low.For solving an above difficult problem, the present invention has designed a kind of novel structure, the planetary speed reducer that bearing capacity is larger.
Summary of the invention
The object of this invention is to provide a kind of novel drive structure of speed reducer, can effectively solve the problem that bearing capacity is limited, transmission efficiency is low that conventional construction form produces.
For reaching above-mentioned purpose, the invention provides a kind of novel drive structure of speed reducer, comprise carrier bearing, the output shaft of planetary drive frame, output stage and be arranged on the elastic buffering pad of output shaft inside.Its special way is, secondary drive frame engages with output shaft, and its spline changes new structure in carrier bearing inner side by conventional construction in carrier bearing outside, and the motivation transfer motion part of this drive mechanism does not need to connect gear and connects, carrier bearing and output shaft simple in structure, bearing capacity is large.
The invention has the beneficial effects as follows: carrier bearing can increase radial dimension, improve bearing capacity, bring abundant space to the layout of other parts simultaneously; Carrier bearing outer ring is arranged on the inside projection of casing by conventional construction, changes into and being directly installed on box body wall; Carrier bearing and its mounting flange can be parts of entirety, can be also that multiple parts combine.Output shaft is hollow-core construction, and the crowned teeth spline joint on internal spline and planetary drive frame is made in axle inside; Axle is outside to be connected with carrier bearing inner ring, and output shaft radial dimension increases, and inside is made hollow, has both improved the bearing capacity of output shaft, has alleviated again weight.Save the connection gear in traditional drive mechanism, reduced part number, saved cost, reduced rate of fault.Elastic buffering pad is installed on output shaft inside, and the planetary drive frame in quick condition is had to axial buffer protective action.Elastic buffering pad and planetary drive frame surface of contact are cambered surface, have axially, automatic capturing positioning action radially.
Brief description of the drawings
Below with reference to accompanying drawing, the present invention is described in further details.
Fig. 1 is the structural representation of new structure speed reducer involved in the present invention.
Fig. 2 is the structural representation of conventional construction speed reducer.
In figure: 1, protecgulum 2, one-level sun gear 3, one-level planet wheel 4, one-level bogie 5, secondary solar gear 6, secondary planet wheel 7, secondary drive frame 8, connection gear 9, carrier bearing 10, casing 11, output shaft 12, elastic buffering pad.
Embodiment
As shown in Figure 1, new structure carrier bearing inner ring is installed on output shaft, and carrier bearing outer ring is directly installed on box body wall, and the radial dimension of carrier bearing (9) increases, and bearing capacity improves.Carrier bearing outer ring and its mounting flange are one-piece parts, and can be also has more than one multiple part combination simultaneously.
As shown in Figure 1, secondary drive frame (7) axial end portion external process becomes crowned spline, and secondary drive frame (7) can be a part with its crowned spline, can be also that more than one multiple part combines.
More than enumerating is only to illustrate of the present invention, does not form the restriction to protection scope of the present invention, within the every and same or analogous design of the present invention all belongs to protection scope of the present invention.
