Description
Technical field
The utility model belongs to transmission assembly field, specifically, particularly relates to a kind of main drive gear of second gear electric vehicle transmission assembly.
Background technique
Existing electric vehicle transmission assembly only has a gear, namely can not speed change, its output speed and moment of torsion constant, can not adjust accordingly according to road conditions condition, so just cause its road conditions adaptive capacity poor.
In order to improve the road conditions adaptive capacity of speed changer, need now to redesign a electric vehicle transmission assembly with two gears.Meanwhile, in the design process, need a kind of main drive gear of respective design, it is firm that this main drive gear is not only wanted to install, but also need can reliably transferring power, goes back Structure of need in addition compact, lightweight.
Model utility content
Technical problem to be solved in the utility model is the main drive gear providing a kind of second gear electric vehicle transmission assembly, and it is firm that this main drive gear can not only be installed, and can also reliably transferring power, and structure is also compact in addition, lightweight.
The technical solution of the utility model is as follows: a kind of main drive gear of second gear electric vehicle transmission assembly, it is characterized in that: the thickness of the body (1) of this main drive gear is 22mm, and the aperture of body (1) center hole is 95mm, and the outward edge of body (1) is a circle profile of tooth; The center of described body (1) left side has the first lightening grooves (1a), and the diameter of this first lightening grooves is 147mm, and the degree of depth of the first lightening grooves (1a) is 14mm; The center of described body (1) right side has the second lightening grooves (1b), and the diameter of this second lightening grooves is 147mm, and the degree of depth of the second lightening grooves (1b) is 2mm; Described body (1) circumferentially evenly has 8 bolts and via hole (1c) is installed, the aperture that via hole installed by this bolt is 11mm, the bottom land of first and second lightening grooves (1a, 1b) and pay wages respectively in the two ends of bolt installation via hole (1c).
During assembling, this main drive gear is sleeved on transmission shaft by center hole, and the bolt installed in via hole (1c) by being located in 8 bolts is fixedly connected with, by the profile of tooth transferring power of outer circular edge during transmission, and reliable transmission.In addition, the utility model is designed with first and second lightening grooves, and the parameter designing of these two lightening grooves is reasonable, can loss of weight effectively under the prerequisite ensureing structural strength, thus reduces weight of the present utility model.
As optimal design, the arc section smooth transition respectively by R5mm between the cell wall of described first and second lightening grooves (1a, 1b) and bottom land, so just can under the prerequisite ensureing structural strength, loss of weight effectively.
As preferably, the material of described body (1) is 20CrMnTiH, and shaping by forging.The hardness of this gear, intensity and wear resistance so just can be made all relatively good, and forge shaping technical maturity, be convenient to manufacture.
Beneficial effect: this main drive gear is sleeved on transmission shaft by center hole, and the bolt installed in via hole by being located in 8 bolts is fixedly connected with, by the profile of tooth transferring power of outer circular edge during transmission, reliable transmission; In addition, the utility model is designed with first and second lightening grooves, and the parameter designing of these two lightening grooves is reasonable, can loss of weight effectively under the prerequisite ensureing structural strength, thus reduce weight of the present utility model, and hardness of the present utility model, intensity and wear resistance are all relatively good, easy to manufacture.
