Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of compact in design, bearing capacity strong, can transmit high-power, mechanical efficiency is high and many rectangular axis of installation form hardened face gear speed reducer.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of rectangular axis hardened face gear speed reducer, comprise casing, input shaft, gear shaft, gear and output shaft, it is characterized in that: described input shaft is a bevel gear shaft, an end that is described input shaft is the awl toothing, be equipped with by dynamic bevel gear on the described gear shaft, on the described output shaft gear is installed, the awl tooth and the described driven gear of described input shaft are connected with a joggle, described gear shaft is connected described input shaft with gear engagement on being installed in output shaft, gear shaft and output shaft are installed on the casing.
The utility model can also adopt following technological scheme:
Described gear shaft comprises one-level gear shaft and secondary gear axle, described gear comprises one-level gear and secondary gear, describedly be installed on the one-level gear shaft by dynamic bevel gear, described one-level gear is installed on the secondary gear axle, and one-level gear and one-level gear shaft are connected with a joggle, described secondary gear is installed on the output shaft, and secondary gear and secondary gear axle are connected with a joggle.
Described input shaft, gear shaft, output shaft and gear all adopt the low-carbon alloy steel to make.
The material of described casing is a cast iron.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technological scheme, the input shaft that is described deceleration is a bevel gear shaft, the awl toothing of one end be installed in being meshed on the gear shaft, described gear shaft and the gear engagement that is installed on the output shaft by dynamic bevel gear.The speed reducer of said structure is compared existing parallel axes or turbine orthogonal formula speed reducer, and not only compact structure be convenient to install, and bearing capacity is strong, can pass on high-power.
Critical components such as reducer gear are selected high-quality low-carbon alloy steel for use, belong to the hard flank of tooth.The force intensity that is subjected to of material improves greatly, thereby has bigger bearing capacity.Because gears at different levels have guaranteed stable working through high-precision roll flute processing, noise is low, mechanical efficiency height, and long service life, reliability height.Casing adopts high strength cast iron, guarantees that product is in use safe and reliable.
