Description

Hardened gear face helical speed reduction gear
Technical field
The utility model relates to a kind of retarding device, particularly a kind of Hardened gear face helical speed reduction gear.
Background technique
Speed reducer plays the effect of coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and it is a kind of comparatively accurate machinery, and it installs object for reducing rotating speed, increases torque.Mainly apply in automobile, processing, building or metallurgical equipment.
Traditional cycloid speed reducer only has an output terminal, and as in process equipment, namely only can implement to slow down for a device or drive part, efficiency is lower, and fragile, maintenance difficult.
Summary of the invention
For the deficiency that prior art exists, the utility model provides the Hardened gear face helical speed reduction gear that a kind of transmission efficiency is high, easy to maintenance, bearing capacity is large.
For achieving the above object, the utility model provides following technological scheme: a kind of Hardened gear face helical speed reduction gear, include motor and the reducing gear with motor linkage, described reducing gear includes shell, be located in shell and the input shaft assembly of motor linkage and the output shaft by gear train transmission, it is characterized in that: described shell is added to be provided with two and to be set up in side by side on shell and the output shaft of synchronous operation, described input shaft assembly includes and the input shaft of motor linkage and the transmission shaft that links with input shaft, linked by primary speed-down gear train between input shaft and transmission shaft, this primary speed-down gear train includes the primary speed-down small gear that is sheathed on input shaft and is sheathed on the primary speed-down gearwheel engaged on transmission shaft and with primary speed-down small gear, described gear train includes the double reduction small gear be sheathed on transmission shaft and the double reduction gearwheel be sheathed on respectively on output shaft.
Adopt technique scheme, by establishing two to be set up in parallel and the output shaft of synchronous operation shell is added, the transmission efficiency of this speed reducer is improved, can simultaneously to two devices or the mechanism for implementing interlock of process equipment, and the set-up mode of gear train is reasonable, slowing effect is good.
The utility model is set to further: output shaft is in outside the side face in shell and is arranged with full-complement cylinder roller bearing, and its axial the other end is arranged with selfaligning roller bearing.
Adopt technique scheme, selfaligning roller bearing can the error of compensating shaft bore misalignment, and full-complement cylinder roller bearing adopts inner ring without the structure of rib, can be convenient to the adjustment of output shaft axial position, solves the problem of the bearing dieback that processing and assembly error cause.Full-complement cylinder roller bearing is more more than general roller bearing roller simultaneously, and bearing capacity is larger.Make the applying working condition that deceleration functional adaptation is more severe.
The utility model is further set to: shell is provided with the fitting seat that power supply machine is installed, and motor is fixedly arranged on shell by this fitting seat.
Adopt technique scheme, arrange like this and motor and shell are combined as a whole, structure is more compact, the risk lost efficacy of cutting down the number of intermediate links.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of the utility model embodiment.
Embodiment
As Fig. 1, a kind of Hardened gear face helical speed reduction gear shown in Fig. 2, the reducing gear 2 including motor 1 and link with motor 1, reducing gear 2 includes shell 21, be located at the input shaft assembly 22 that links with motor 1 in shell 21 and the output shaft 24 by gear train 23 transmission, shell 21 is added to be provided with two and to be set up in side by side on shell 21 and the output shaft 24 of synchronous operation, input shaft assembly 22 includes the input shaft 221 linked with motor 1 and the transmission shaft 222 linked with input shaft 221, linked by primary speed-down gear train between input shaft 221 and transmission shaft 222, this primary speed-down gear train includes the primary speed-down small gear 223 that is sheathed on input shaft 221 and is sheathed on the primary speed-down gearwheel 224 engaged on transmission shaft 222 and with primary speed-down small gear 223, gear train 23 includes the double reduction small gear 231 be sheathed on transmission shaft 222 and the double reduction gearwheel 241 be sheathed on respectively on output shaft 24.In such scheme, be set up in parallel and the output shaft 24 of synchronous operation by setting up two on shell 21, the transmission efficiency of this speed reducer is improved, can simultaneously to two devices or the mechanism for implementing interlock of process equipment, and the set-up mode of gear train is reasonable, slowing effect is good.
In the utility model embodiment, output shaft 24 is in outside the side face in shell 21 and is arranged with full-complement cylinder roller bearing 3, and its axial the other end is arranged with selfaligning roller bearing 4.Selfaligning roller bearing 4 can the error of compensating shaft bore misalignment, and full-complement cylinder roller bearing 3 adopts inner ring without the structure of rib, can be convenient to the adjustment of output shaft 24 axial position, solves the problem of the bearing dieback that processing and assembly error cause.Full-complement cylinder roller axle 3 holds more more than general roller bearing roller simultaneously, and bearing capacity is larger.Make the applying working condition that deceleration functional adaptation is more severe.
In order to make the linkage structure between motor 1 and shell 21 more compact, shell 21 is provided with the fitting seat 211 that power supply machine 1 is installed, and motor 1 is fixedly arranged on shell 21 by this fitting seat 211.And the output of motor 1 can adopt anti-impurity sealing configuration, motor 1 oil sealing can be protected well, prevent the output of motor 1 from occurring leaking oil condition.
