Description
Technical field
The utility model belongs to mechanical transmission device technical field, relates to a kind of gear, the driving gear particularly in a kind of automotive transmission.
Background technique
Gear wheel rim has tooth and can engage the mechanical component transmitting motion and power continuously, there is the advantages such as transmission efficiency is high, velocity ratio is accurate, power range is large, gear can also by with other mechanical parts engagement driving, realize change rotating speed and moment of torsion, change moving direction and change the functions such as forms of motion; Gear shaft is the cogged transmission shaft of band; The extensive use in industrial products of gear associated mechanisms, its design and manufaction level directly has influence on the quality of industrial products.
Speed changer is the important spare part of automobile, and it can change the velocity ratio of motor car engine Power output, expands the excursion of driving wheel torque and rotational speed, to adapt to the driving conditions of often change, motor is worked under favourable operating mode; In the constant situation of hand engine rotation, automobile can be fallen back traveling; Utilize neutral, interrupt transmission of power, can to start, speed change with motor, and be convenient to shifting of transmission or carry out Power output, its function is mainly realized by multiple different gears meshing.
China's patent (notification number: CN201606459U; Publication date: 2010-10-13) disclose a kind of single middle-shaft multi-gear automobile speed changer, it is made up of interconnective major and minor speed changer, basic trnasmission comprises an axle, two axles, two axles are provided with comprise one, multiple main tank synchronizer of reverse gear synchronizer and forward gear and reverse gear, be in parallelly provided with a jack shaft; Auxiliary transmission comprises odd-side main shaft, odd-side main shaft reduction gear is meshed with the axle tooth be arranged on odd-side jack shaft, driving gear on odd-side jack shaft is meshed with the odd-side actuation gear on two axles, is provided with auxiliary box synchronizer between odd-side actuation gear and odd-side main shaft reduction gear; The main tank top cover with two H operating mechanism and auxiliary box cylinder interlock is passed through between major and minor speed changer.
Because driving gear is meshed from different gears in the process of transmitting torque, need to bear different power, and gear can produce friction in intermeshing process, seems particularly important to the protection of driving gear.Can greatly reduce friction factor between gear by the lubrication of lubricant oil in prior art, reduce wear.In speed changer disclosed in above-mentioned patent like the prior art, in casing, inject Lubricant on Gear tooth bar place lubricate, but lubricant oil can be lossy in Long-Time Service usually, when the quantity not sufficient of lubricant oil is to cover all gear structures, be positioned at gears meshing to be topmost difficult to ensure effectively lubricating, thus occur wearing and tearing.
Summary of the invention
The problems referred to above that the utility model exists for existing technology, provide the driving gear in a kind of automotive transmission, technical problem to be solved in the utility model is: the lubrication how realizing driving gear more fully.
The utility model object realizes by following technical proposal:
Driving gear in a kind of automotive transmission, described gear comprises the body of column, along body shaft to offering the mounting hole run through in the middle part of described body, the uniform some teeth of described body edges, it is characterized in that, teeth groove is formed between two adjacent teeth, described body two ends all have the baffle plate that can seal described teeth groove end, teeth between adjacent two teeth groove offer the through hole of connection two teeth groove, described through hole be positioned at described teeth bottom and and the bottom land of described teeth groove there is interval.
Its principle is as follows: in the technical program, driving gear is used for the moment of torsion transmission in speed changer, driving gear is arranged in casing, the machine oil that oilgear is used is marked with in usual casing, when after machine oil loss, all gears can not be covered completely, this driving gear is by arranging baffle plate in teeth groove end, teeth groove is made to form the shoe cream room that can hold machine oil, teeth are when rotating around body axis, teeth groove can from lower position by the machine oil in casing stored in teeth groove, and bring to high position, then teeth are given by the through hole of connection two teeth groove that teeth are offered by machine oil, thus strengthen machine oil to the lubrication effect of teeth, reduce wear.
In driving gear in above-mentioned automotive transmission, the quantity of described through hole is at least two and through hole on adjacent two tooth bars is all dislocatedly distributed.Through hole has two at least, and be convenient to after machine oil takes eminence to, can flow to smoothly in other teeth groove and teeth, realize lubrication, through hole is dislocatedly distributed simultaneously is to prevent machine oil from directly passing from adjacent teeth through hole, and can not realize stopping lubrication.
In driving gear in above-mentioned automotive transmission, described baffle plate between adjacent two teeth and the exterior edge face of described baffle plate between calibration circumference and tooth root circumference, the center of described through hole is lower than the exterior edge face of described baffle plate.The excessive height of baffle plate, can affect engaging each other between gear, and the height of baffle plate is too low, then machine oil is easy to run off, and is convenient to deposit and moves to high-order teeth place.
In driving gear in above-mentioned automotive transmission, the side lower of described teeth both sides has rounding with the diapire place of combining of described teeth groove.Machine oil enters the rotation along with body after teeth groove, and can flow in another teeth groove by through hole, in this process, rounding not only can increase teeth groove volume, and is convenient to the smooth outflow of machine oil, makes machine oil lubricate teeth comprehensively.
In driving gear in above-mentioned automotive transmission, the outer surface of described teeth is plane, and the bi-side of described teeth are cambered surface and are less than the thickness in the middle part of described teeth with the thickness of downside on the upside of described teeth.The side of teeth is the sidewall of teeth groove, and the two side of such teeth groove is recessed to form larger shoe cream room to both sides, can hold a large amount of machine oil and lubricate it in teeth groove, reduces the wearing and tearing of teeth.
Compared with prior art, the driving gear in the utility model has the following advantages:
1, in the technical program teeth groove can from lower position by the machine oil in casing stored in teeth groove, and bring to high position, then give teeth by the through hole of connection two teeth groove that teeth are offered by machine oil, thus strengthen machine oil to the lubrication effect of teeth, reduce wear.
2, in the technical program by arranging the shape of teeth, make the two side of teeth groove be recessed to form larger shoe cream room to both sides, a large amount of machine oil can be held in teeth groove it is lubricated, reduce the wearing and tearing of teeth.
