Problems solved by technology
The gears on the crankshaft and the balance shaft of the existing balance shaft device are all steel gears, and there is a transmission mode in which both sides of the gear are meshed with the gears at the same time. Bearings and needle roller bearings are paired for support, steel gear meshing hard friction is easy to accelerate damage, which will cause sharp and harsh noises from the gears, deep groove ball bearings and needle roller bearings are inconvenient to install and take up a lot of space, which will increase the size of the balance shaft device accordingly and weight

The invention discloses an automobile engine balance shaft device which comprises a base body and at least two balance shafts. The balance shafts are provided with balancing weights, one balance shaftis used as a driven balance shaft, the other balance shafts are used as transmission balance shafts, each transmission balance shaft is sleeved with an input gear and a output gear, the driven balance shaft is sleeved with a driven gear, the driven gear and the output gear are engaged in pairs, the transmission balance shafts are in one-to-one engaged transmission through the output gear and theinput gear, the transmission balance shafts are in engaged transmission with a gear on an engine crankshaft through the input gear, wheel teeth of the driven gear and the input gear are injected and molded to resin wheel teeth, and the transmission balance shafts and the driven balance shaft are supported and installed on the base body through self-lubricating bearings.
Description
technical field [0001] The invention belongs to the field of automobile engine accessory devices, and in particular relates to an automobile engine balance shaft device. Background technique [0002] The balance shaft device used in automobile engines is used to reduce engine vibration, reduce engine noise and prolong the life of the engine. The main structure of the balance shaft device is a balance shaft with a follow-up rotating weight. Incomplete upward setting can form an unbalanced centrifugal force, and paired meshing gears are respectively set on the balance shaft and the crankshaft. The gears on the crankshaft and the balance shaft of the existing balance shaft device are all steel gears, and there is a transmission mode in which both sides of the gear are meshed with the gears at the same time. Bearings and needle roller bearings are paired for support, steel gear meshing hard friction is easy to accelerate damage, which will cause sharp and harsh noises from the ...
