Therefore, need easily there is the problems such as worm-gear toothing surface wear, spring tooth, screw shaft fracture and casing explosion for the reductor of Chipless cutting machine, reductor is improved.
Utility model content
The purpose of this utility model is exactly the problem existing in order to solve prior art, and a kind of circle-arc tooth Bevel Gear Transmission reductor for Chipless cutting machine is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of circle-arc tooth Bevel Gear Transmission reductor for chipless cutting, comprise casing, it is characterized in that, on described casing, by bearing, bevel gear power shaft is installed, bevel gear is also installed on casing, and described bevel gear power shaft engages with bevel gear, and described bevel gear has connected output hollow shaft, described output hollow shaft has connected a metallic sheath, is provided with the screw rod that is mated rotation in described metallic sheath.
Further, described circle-arc tooth Bevel Gear Transmission reductor is also provided with input axle sleeve.
The utility model is provided with power shaft cover and is used for fixing the centralized positioning of axle and bearing and does not allow it because vibrations and being shifted when running.
Further, the bevel gear on described bevel gear and bevel gear power shaft is circular-arc bevel gear.
High, the bearing capacity of circular-arc bevel gear contact strength of tooth surface that the utility model adopts is large, can bear large axial force, and it can make transmission steady, contributes to reduce noise.
Further, the described circular-arc bevel gear number of teeth is to avoid making gear to produce the minimum number of teeth of Undercutting Phenomenon.
The circular-arc bevel gear number of teeth of the present utility model, meeting the desirable minimum number of teeth in gearratio requirement situation, obtains reduction box volume and spatial design a little bit smaller, saves space and material, reduces production costs.In addition, reduction box can adopt quality material casting, increases wall thickness dimension, makes its intensity large.
Further, described bevel gear power shaft and output hollow shaft are 90 degree vertical relations.
Further, described metallic sheath is threaded engagement with coordinating of screw rod.
Further, described bevel gear and output hollow shaft are connected to screw attachment.
Further, described output hollow shaft and metallic sheath be connected to screw attachment.
Further, described bevel gear power shaft is arranged on casing by taper roll bearing.
Further, described output hollow shaft is arranged on casing by taper roll bearing.
The taper roll bearing that the utility model adopts can bear radial and axial load simultaneously, and assurance power is steadily exported.
Further, described screw rod end is provided with fixing tool rest, and described fixing tool rest is provided with cutting tool.
The cutting tool that the utility model screw rod end arranges, with screw rod rectilinear motion, is realized incising pipes.
Compared with prior art, the beneficial effect the utlity model has is:
The utility model adopts the gear teeth of circular-arc bevel gear transmission, and contact strength of tooth surface is high, and bearing capacity is large, and stable drive prevents that the phenomenon such as worm-gear toothing surface wear, spring tooth from occurring, contributes to reduce noise; In addition, the number of teeth of circular-arc bevel gear is to avoid the minimum number of teeth that makes gear produce Undercutting Phenomenon to make reduction box size decreases, has saved material and space, reduces production costs.
