Description

一种调节汽车座椅靠背的电机齿轮减速机构
技术领域
本实用新型涉及一种减速机构，特别涉及一种调节汽车座椅靠背的电机齿轮减速机构。
背景技术
普通的用于调节汽车座椅靠背的电机齿轮减速机构，由于为了适应在调节汽车座椅靠背的角度时，旋转轻柔、舒适，所以要求电机齿轮减速机构的减速比较大，因此齿轮容易损坏。
目前，一般采用双齿轮或加大齿轮的方法来达到加强齿轮强度的目的，对于双齿轮结构，参见图1，由一根涡杆1两侧分别带动两个涡轮2向同一方向旋转，两个涡轮2上分别同轴固定一个塑料输入齿轮3，两输入齿轮3共同带动一个输出齿轮4，这样的涡轮2需要有两段方向不同的螺纹，因此加工难度较大，对模具的要求很高，所以成本较高，且所占空间较大；对于加大齿轮的结构，又会增加座椅的安装难度，且会降低乘车的舒适性。可见，以上解决办法均存在自身无法克服的缺陷。
发明内容
本实用新型克服了现有技术的缺点，提供了一种强度高，加工难度小，结构紧凑的调节汽车座椅靠背的电机齿轮减速机构。
本实用新型的一种调节汽车座椅靠背的电机齿轮减速机构，电机输出端连接一个涡杆，涡杆与涡轮相啮合，与所述涡轮同轴固定一个输入齿轮，所述输入齿轮与输出齿轮相啮合。
本实用新型的一种调节汽车座椅靠背的电机齿轮减速机构，在不改变总速比的情况下，采用了两级减速，加强了输入齿轮的强度，且更便于加工、安装，整体齿轮减速机构结构紧凑，体积较小，同时满足了对电机齿轮减速机构强度和寿命的要求。
附图说明
图1表示双齿轮结构的示意图；
图2表示本实用新型实施例的结构示意图。
具体实施方式
参照附图2，将详细叙述本实用新型的具体实施方式。
本实用新型的一种调节汽车座椅靠背的电机齿轮减速机构，电机输出端连接一个涡杆1，涡杆1与涡轮2相啮合，与所述涡轮2同轴固定一个输入齿轮3，所述输入齿轮3与输出齿轮4相啮合，所述输出齿轮4输出端与汽车座椅靠背相连接，带动汽车座椅靠背转动。
为了加强所述齿轮减速机构的强度，所以输入齿轮3也可以采用金属材料，而涡轮2和/或输出齿轮4可以采用塑料材料。
本实用新型的齿轮减速机构通过两级减速，可以将电机的输出转速3000±800转/分钟，减为22±2转/分钟，第一级涡杆，涡轮减速器的减速比为25-45∶1，优选37∶1，第二级齿轮减速器的减速比为34-43∶8-12，优选37∶9。
当然，按照以上所述的齿轮等强度传动机构的结构，本领域的技术人员很容易根据已知的输入、输出的转速比，计算并设计出相应的两级减速机构。
这样的结构，可以达到在相同速比和强度下，更便于加工、安装，同时满足了对电机齿轮减速机构强度和寿命的要求。
