Description
Technical Field
The utility model relates to a reduction gear technical field especially relates to a bevel gear drive mechanism.
Background
Bevel gear transmission is widely applied to industrial transmission equipment, vehicle differentials, locomotive ships and other equipment as a common power transmission device. The traditional bevel gear transmission mechanism is characterized in that a driving wheel large gear drives a driven wheel small gear to transmit in a secondary transmission device so as to ensure high precision, but the traditional bevel gear transmission mechanism has great limitation on transmission ratio. Or the driving wheel pinion drives the driven wheel bull gear, but the transmission precision can not be ensured.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned technique, and provide a bevel gear drive mechanism.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a bevel gear transmission, characterized in that: the worm gear mechanism comprises a worm, a worm gear shaft, a first bevel gear, a second bevel gear, a bevel gear shaft and a box body; the worm wheel is meshed with the worm, two ends of the worm are connected with the box body through bearings, the worm wheel is fixed on a worm wheel shaft, two ends of the worm wheel shaft are connected with the box body through bearings, the first bevel gear is fixed on the worm wheel shaft, the first bevel gear is meshed with the second bevel gear, the second bevel gear is fixed at one end of the bevel gear shaft, and the bevel gear shaft is connected with the box body through bearings.
Preferably, a case cover is fixed to an upper portion of the case body.
The utility model has the advantages that the mechanism can realize heavy load and high precision transmission of the speed reducer. The torque and the speed are greatly reduced mainly through the meshing of the worm gear and the worm, and the high-precision transmission is realized through the meshing transmission of the bevel gear set. The structure of the bevel gear shaft is improved, so that the secondary transmission device is prevented from vibrating in meshing transmission after heavy load, and the transmission precision is influenced.

Detailed Description
Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in fig. 1, a bevel gear transmission mechanism includes a worm 1, a worm wheel 2, a worm wheel shaft 3, a first bevel gear 4, a second bevel gear 5, a bevel gear shaft 6, and a case 7; the worm gear is engaged with the worm, and the worm is fixed in the box body through a tapered roller bearing 32906 at two ends and used as a support. The worm gear and the worm form a primary speed reducer by meshing.
The worm wheel is fixed on the worm wheel shaft, two ends of the worm wheel shaft are connected with the box body through bearings, the first bevel gear is fixed on the worm wheel shaft and meshed with the second bevel gear to form a secondary speed reducer, the second bevel gear is fixed at one end of the bevel gear shaft, and the bevel gear shaft is connected with the box body through bearings. A box cover is fixed on the upper part of the box body.
The worm wheel, the worm, the transmission shaft, the bevel gear and the bevel gear shaft are made of No. 45 materials, and after the normalizing treatment and the processing, the surface is carburized and quenched. The box body and the box cover are made of HT200, and after normalizing processing, quenching and tempering are carried out, and finally surface carburizing and quenching are carried out.
The working steps and the principle are as follows: the motor inputs power through the input worm, and the worm realizes by a wide margin one-level deceleration through the meshing with the worm wheel, and the worm wheel drives transmission shaft and subassembly and rotates, thereby the bevel gear on the transmission shaft realizes the second grade through meshing with output shaft bevel gear axle and carries out the output of power.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
